How PCM Protects Equipment in Harsh Chemical Environments

No facility’s processes can be fully efficient if the equipment isn’t well maintained and in optimal condition. Yet when using harsh or unstable chemicals, facilities often risk damage and premature failure of their equipment.

Today’s pharmaceutical and biotechnology plants, for instance, must be able to produce numerous products while meeting both traditional and advanced needs for product purity, cleanability, durability and, of course, low maintenance costs. If a stainless steel vessel reacts with a chemical, the entire batch of medicine or other product being produced must be tossed – wasting both time and money. In environments like this, traditional stainless steel and glass don’t necessarily deliver the best results.

With unmatched chemical resistance, fluoropolymer coatings can protect a facility’s capital investments in machinery and equipment, not to mention time.

Compatible with most pharmaceutical or biochemical processes, fluoropolymer coatings are non-reactive, so there are no corrosion byproducts to contaminate processes. Teflon® coatings are extremely pure, and unlike untreated stainless steel or glass, they were made specifically to resist the absorption of chemicals.

Teflon® also provides smooth non-wetting hydrophobic surfaces that resist bio-film buildup, and can be used with extremely strong cleaning solutions and steam-in-place processes.

Finally, unlike stainless steel, chemically resistant Teflon® doesn’t require costly passivation or electropolishing, nor does it crack like glass, meaning that maintenance costs will be lower.

At PCM, we’re proud to offer DuPont™ Teflon® industrial coatings that, with almost total chemical inertness, provide extreme chemical protection.


Inside the Teflon® Family

In previous blogs, we have spoken at length about the wonders of DuPont’s Teflon®.  There is no doubt that Teflon® has demonstrated versatility unmatched by any other engineering material. However Teflon® is not just one product but in fact an amazing group of different technologies under one famous umbrella. Let’s take a look at some of the different technologies that make up the Teflon® family.


Polytetrafluoroethylene (PTFE) is a fluorocarbon solid that is hydrophobic, which means that it can’t be made wet. Because of its strong carbon-fluorine bonds, it is extremely non-reactive. It can also be used as a lubricant to reduce friction and wear. Typical applications include heat exchangers, molds, cruise control parts, filters, and carburetor shafts.


Fluorinated ethylene propylene (FEP) is what is referred to as a copolymer. It is a combination of hexafluroropropylene and tetrafluroethylene. It is similar to PTFE, but is softer and thus more easily formable. Therefore, it is utilized in chemical equipment like impellers, mixing tanks, valves, and pumps.


Perfluoroalkoxy (PFA) is yet another fluoropolymer that is a lot like PTFE. The difference being that, much like FEP, it is easily formable. Also PFA melts at 305°C while FEP does so at 260°C. PFA is great for chemical equipment but also Silicone wafer manufacturing equipment and molds.


Ethylene terafluoroethylene (ETFE) is a fluorine-based plastic polymer which is extremely corrosion-resistant. In many ways it is physically the strongest of the four technologies. It has a very high melting temperature and can bear 400x its own weight. It is used for heavy duty chemical equipment and polystyrene molds.

PCM and the changing world of printing

Printing press and TeflonThere was a time in this country when major cities had tens of different newspapers.  In the 1940s New York City had as many as 11 daily newspapers fighting for readers. At the time, of course, there was no internet or CNN, so if you wanted to learn the latest news the paper was the best way to get it. Times have certainly changed.  To put it in perspective, we have the same number of newspapers in the US as we did in 1890. Of course, we also have 243 million more people living in eight more states so that number is a good example of the newspaper’s downfall.

But guess what – no matter how many papers or magazines go online, people will still demand the printed word. From books to magazines to local supermarket sales flyers, the country and the world will be printing things on paper for a long time to come. At PCM, our Product-22, Teflon®, and other coatings are perfect for keeping inks, adhesives, and even paints off machinery. These amazing materials make wash-ups and clean-ups a snap, all while helping reduce downtime and labor costs. Our coatings are perfect for ink pans, mandrels, splashguards, cooling cans, ink fountains, rollers, and many other crucial pieces in the printing process.

If you need to get out the morning edition on time, you can’t afford downtime, especially in today’s more difficult business climate. As long as there is printing, PCM will continue to provide the highest quality and most advanced coatings to anyone who needs them.

Teflon®: More Than Just Teflon®

It is hard to go a day without hearing or reading the word “Teflon.” It has become so ingrained in our modern verbiage that it’s one of those trademark names, like Kleenex® or Post-It®, that gets used to cover a much broader range than it actually means. Teflon® is a little different though: while it may occasionally be used to refer to other non-stick coatings, the real difference is that there are so many different formulations that fall under the Teflon® umbrella, that the single name is now used to talk about 60 or 70 different chemistries.

These formulations include Teflon® PTFE, FEP, ETFE, PFA, and many more. Each of these amazing and groundbreaking formulations has different and often unique characteristics. Teflon® offers coatings that are non-stick, heat resistant, chemical resistant, water resistant, just to name a few. With all these choices, it is easy to get confused. Many of our customers know that they need Teflon® coatings for their machinery, however with 70 to choose from, they don’t always know exactly which formulation is perfect for their needs. That’s why PCM is here. We know everything there is to know about the Teflon® family of coating systems. If someone in the pharmaceutical industry calls us, we know that Teflon® ETFE and PFA are perfect to protect their equipment from harsh chemicals. When commercial bakers need coatings systems, we know that SBS-Teflon® is the right choice for them. It really doesn’t matter the industry, the experts at PCM have the perfect Teflon® coating system solution.

So don’t rely on just anyone when it comes to supplying you with the wonders of Teflon®. Because in the end, Teflon® really is more than just Teflon®.

Gardening with PCM

Gardening shears and scissors with Teflon®-SNothing is lovelier than a beautiful garden. The smells, the colors, it’s all so wonderful and calming. That is if you don’t have to tend to one! Despite the hard work, bug bites, and sunburns, Americans love to garden, and they love to spend money on it as well. U.S. households spent $29.1 billion on their lawns and gardens in 2011 – about $351 per household each year.  Some of those billions go to things like shears and scissors. These implements are great for pruning flowers, cutting grass, and even trimming hedges in cool shapes.  Companies like Fiskars, Klein, and even Martha Stewart make shears and scissors in wide variety of sizes and shapes.

As it turns out, the blades of some of the higher end models are coated with Teflon®. To be more exact, many of these companies use Teflon®-S. This unique Teflon formulation is a self-priming on-coat blend of Fluoropolymer, and we’ve noticed that these companies especially favor the 958 series. Teflon®-S is also perfect for sprinkler ball valves, fan blades, automotive fasteners, boat propellers, and saw blades.

When it comes to gardening, if you combine a high quality metal with Teflon®-S, you get a great pair of shears or scissors. So get out there and start pruning and cutting before the seasons change! Moreover, if you want to learn more about the miracle that is Teflon®-S, contact an expert at PCM today.


Teflon and Golf BallsNothing says summer like a nice round of golf! Experts believe that 24 million people in the United States play golf on a regular basis. Out of those 24 million only 8,000 are professionals, so that leaves many golfers who may lose a golf ball or two (or 12) every time they play a round. It is one of the main reasons that companies like Nike, Titleist, Pinnacle, and Callaway manufacture and ship over 850 million golf balls each year.  Most golf balls come in three varieties: two-piece, three-piece, and dimple-covered shell. Two-piece are the most common and account for about 70% of all sales. The other two are made for better golfers, thus their lower popularity.

The ball itself is made of a combination of plastic and rubber. Most have a solid rubber core with a durable thermoplastic cover. In order to form the cover for the ball injection or compression molding is used. The core is placed in the middle of the mold and then the plastic is injecting into the mold to form the ball. This is where Teflon® coating comes into play. Once the plastic cools and hardens it has to be removed from the mold for painting and coating. As you might imagine, if you have to make a few million balls a year, you can’t risk having them stick in the molds. Teflon® to the rescue! Non-stick coatings allow the manufacturing process to remain fluid and therefore profitable by guaranteeing that every ball will be released from the mold in the proper fashion.  It’s just another great reason why Teflon® and PCM, make your life easier and in this case a lot more fun.

PCM Helps Keep Your Pharmaceuticals Safe

non-stick and chemical resistant coatings for pharmaceutical manufacturingIt seems like everywhere you look you see an ad for the latest prescription drug. From hair loss to heart disease, there is a drug out there to help you live a better, longer, happier life. In 2010 alone, the top 50 pharmaceutical companies sold $539.3 billion in prescription drugs. Industry giants like Novartis, Merck, and Pfizer make big profits, but they also spend unbelievable amounts of money to research, test, and manufacture the drugs that save lives every day.  For every blockbuster drug like Lipitor that can bring in billions of dollars, there are those that never make it despite having millions poured into their development.  So clearly this is an industry that can’t afford mistakes, both for the sake of profits and most importantly, the safety of those they serve.

At PCM, we feel like our non-stick and chemical resistant coatings play a big role in making sure the pharmaceutical companies have one less thing to worry about.

Today’s pharmaceutical and biotechnology plants have to able to produce many different types of products without sacrificing purity, cleanability, durability, and low maintenance costs. PCM helps the biggest names in the business to meet their demands by providing coatings made of fluoropolymers.

Flouropolymer coatings are non-reactive, thus they leave no corrosion byproducts to contaminate processes. Coatings such as Teflon® are extremely pure, and unlike untreated stainless steel or glass, they were made to resist the absorption of chemicals.

With almost half of everyone in the US (48%) taking at least one prescription drug in the last month, safe and consistent fluoropolymer coatings like Teflon® are more important than ever.  As the world leader in non-stick coating and lining technology, PCM is proud that the products we provide help guarantee that each and every pharmaceutical you rely on is made as safely and cost-effectively as possible.

The History of Teflon

Teflon® nonstick coatingWhile known best as a nonstick cookware coating, Teflon® is also used in everything from cars to buildings.

We talk a lot about Teflon® and our amazing and long lasting relationship with DuPont. Yet up to this point, we have told you the fascinating story of how DuPont changed the world when they discovered and introduced the magic that is Teflon®.

The story of the Teflon® brand began on April 6, 1938, at the DuPont Jackson Laboratory in New Jersey.  A DuPont chemist, Dr. Roy J. Plunkett, was working with gases related to the company’s refrigerant products, when he discovered that a frozen, compressed sample of tetrafluoroethylene had polymerized spontaneously into a white, waxy solid to form polytetrafluoroethylene (PTFE).  Turns out Dr. Plunkett had created the world’s first fluoropolymer, which possessed not only outstanding chemical and heat resistance, but also the world’s most slippery surface qualities.

PTFE was registered under the Teflon® brand trademark in 1944 by DuPont.  Since then, DuPont has developed an expanded range of fluoropolymers that have enabled the production of hundreds of vital products that make life safer, more convenient, more affordable, and more sustainable.

Today people are using DuPont fluoropolymers in critical applications in everything from cars and aircraft to buildings and communications devices.  Still, it is for its use on cookware that the Teflon® brand has become one of the world’s most recognized consumer brands, associated with durability and nonstick performance along with convenient and healthy cooking.

Since 1962, PCM has been lucky enough to be a DuPont Licensed Industrial Applicator (LIA). Therefore, everyone at PCM just wanted to take a moment and tip our hats to Dr. Plunkett and all the amazing people at DuPont for making our lives and the world better.

PCM and the Fast Food revolution

PCM and the Fast Food revolutionHere is a number that will jump off the page: In 2011, U.S. restaurants exceeded $600 billion in sales. In 1955, American’s only spent 25% of their food dollar on dining out, but now they spend almost 50%. Along with the rest of the world, America has become a country that eats on the run. In order to keep up with these staggering numbers, the food industry has had to lean heavily on innovative companies like PCM in order to produce an ever-increasing volume of consistent and high quality foodstuffs.

No discussion of the boom in restaurants would be complete without mentioning the explosion of fast food.  In 2009 alone, the top 20 fast food restaurants registered $99 billion in sales at over 118,000 locations. Many of the restaurants rely on baked goods like hamburger buns and sandwich rolls. To keep up with this massive demand, these products have to be made in large quantities. This is where the experts at PCM come in handy.

As an eastern United States licensee of the SBS-Teflon° Non-Stick Pan coating systems, PCM supplies a vast number of different fast food chains with non-stick baking trays and pans. The chains that do use SBS systems cut costs because equipment with DuPont® Teflon lasts 12 times as many baking cycles as  regular silicone glazes. In addition, the SBS systems eliminate the need for pan oil to aid in product release and SBS-Teflon® coatings comply with the FDA and other food-contact regulatory agencies around the world.

So, the next time you have a hamburger or sub at your favorite fast food restaurant, just remember that the bread you’re enjoying most likely came out looking and tasting so great because of one of PCM’s SBS-Teflon® Non-Stick coating systems.

Making Cool things Cooler with Teflon®

Teflon Coated Guitar StringsDupont’s™ Teflon® coating is truly a miracle of modern science. Everything from baking pans to biocompatible surgical instruments are coated in Teflon to prevent sticking, friction, and wetting. However, did you know that Teflon or Polytetrafluoroethylene (PTFE) could actually make your guitar sound better?

In the last fifteen years, a number of guitar string companies including Wyres discovered that coating their strings in Teflon PFT had a number of benefits.  Originally, manufacturers started using Teflon to prevent string corrosion. Many modern guitar strings are made of highly corrosive bronze, which makes it almost impossible to keep them fresh and rust free. By using a protective polymer coating, the alloys in the strings stay oxygen free, which allows them to sound fresher, longer. As an added bonus, the coating also allows manufacturers to eliminate something called finger squeak, which as the name implies, is the terrible squeaking sound that rusted or damaged guitar strings can make when played.  This may not sound like a big deal, but if you are paying $200 an hour to record an acoustic guitar in a studio, nothing will waste time and money like squeaking strings!

While this is not a big part of what we do at PCM, it is a perfect example of how Teflon® plays a role in almost every aspect of modern life. Next time you tell a friend you work in the non-stick coating business and they start asking about frying pans and skillets, you can tell them there’s much more to it than that.
