Polytetrafluoroethylene or as it’s better known ‘PTFE’ is a popular choice in hydraulics systems and components, being a non-stick surface and a highly durable material. However, since PTFE is made up of some of the strongest bonds in organic chemistry, this type of plastic has many different uses across a variety of industries.
Hydraulic Components and Sealing
The most common use for PTFE is for parts used in seals, gaskets and steam valves that are used to handle caustic fluids. The durability of this plastic has made it popular for a variety of hydraulic fittings like these as well, especially seals used in steam and high temperature applications. The rating for continuous temperature is 500 degrees F, while maintaining physical properties. Virgin PTFE sheets and rods are also excellent materials for wear and slide machined parts found in pumps and manifolds, having a non-stick surface that won’t experience nearly as much wear and tear as other materials.
Thermal Stability for Vehicle Engines
One of the major benefits of PTFE is its high thermal stability, which has made it popular for use in fuel hose linings, gaskets, seals, and other engine components. Its exceptionally long lifespan, high heat resistance and excellent water resistance makes PTFE an excellent choice for making parts such as wiper blades and other exterior components for vehicles.
High Resistance for Chemical Production and Processing

PTFE is a highly durable and corrosion resistant material, and so it has become a popular choice of material for a variety of chemical processing applications. It does not melt or erode under the extreme conditions often found in chemical plants, and can is often used to make components that transport corrosive chemicals and other materials.
Excellent Protection for Electronics
Another industry that often takes advantage of PTFE’s benefits is in the electronics manufacturing. PTFE is commonly used for insulation, semiconductor components, and circuit boards. It offers high quality insulation properties even under harsh conditions, and its electrical conductivity can be increased using fillers such as copper. PTFE has been successfully used in a wide range of different electronics components for many applications, from automobiles to aircraft, where the more delicate electronics components need to be able to survive high temperatures or highly corrosive environments.

We have all heard the upset consumer angry about the ‘Cheap Plastic’, normally about a thin plastic bag or water bottle that just broke during normal use.
“I thought ALL Plastic Was A Just A Cheap Material?”
We do hear this question regularly. And, maybe, in years gone by Plastic was that Cheap material.
Back in the 50′s and 60′s, plastics were very inexpensive, and were very limited in types, grades and availability.
What caused this to change?
Plastics are primarily produced from Oil and several Oil by-products. As oil pricing has skyrocketed from the 50′s, so did the low end plastic material pricing.
In addition, a new generation of high tech, mechanical and engineering grades of plastic we developed. These performance plastics replace metals and other substrates in manufacturing. They out live and out perform most materials at a fraction of the cost of the material it replaces.
Isn’t Cheap better?
All materials are not designed to the same standard. This is true with plastics as well. Choosing the wrong plastic for a project can be a costly mistake. All engineering perimeters should be considered: strength, impact, sunlight, water absorption, electrical resistance, temperature range, etc. We’ve all witnessed the ‘cheap’ plastic kids toy that lasts but a couple of days, the clip or cover in your car breaks off, the inexpensive outdoor furniture and so on. These are examples of under designed or choosing a material for its resin cost, not its physical properties. Thus, no, cheaper is not better. Cost should be just one of your decision criteria. The overall ‘performance’ of the material you require will dictate the type, grade and overall cost of the material. We supply materials from very inexpensive to some that are very expensive. These price differences are based on the significant differences in many of today’s high performance plastic materials.
What Should You Do?
The answer is really quite easy. Ask.
Talk to one of our experienced ‘Plasticologists’ and tell them your requirements. You’re input, and a little time to answer some questions could save you enormous time and expense in your finished parts. All plastics are not created equal, and neither are all plastic suppliers. Give us a try, and take the guess-work out of choosing the right material for your job. Most Performance Plastic materials outlast other raw materials, even metals. Check the physical properties, and using the right material for the application, could mean your parts may last decades without needing maintenance or lubrication.
Some of our lower cost materials: HDPE, PVC, Styrene – are less expensive, but not cheap. Each with very specific strong points, and yes, weak areas as well. Contact us with any questions you may have about the best material for your project as ‘one size does not fit all’.
‘Cheap plastic’ is most likely not the best plastic for your application.

PTFE is an incredibly popular type of plastic material, with widespread use and many different applications. Though its popularity has waned–and its applications changed along with how this particular material is developed–PTFE is still an excellent choice of material for industrial equipment and electronic parts.
What is PTFE?
PTFE is well-known for its non-stick properties and also known for being incredibly easy to machine and fabricate, and thus has been used extensively in industrial and electrical applications, especially for bearings, seals, valves, and fittings.
The Properties of PTFE
PTFE and the family of Fluoropolymers have many excellent physical properties that are not just for high temperature and chemical applications, but many others as well.
The basic properties of PTFE include:
Slippery and Non-stick surface regardless of rod or sheet form
Excellent Wear and Superior Chemical Resistance
Continuous Operating Temperatures up to 500oF
ITAR and RoHS compliance
At Industrial Plastic Supply, we also stock and supply a massive range of PTFE in many different sizes and shapes, including extruded rod, molded rod, thin sheet, thin and thick plate, and film. We can also mold PTFE tubing according to specific customer specifications.
The Applications of PTFE
PTFE has seen wide use in a variety of parts and equipment, especially in industrial applications, electronics, aircraft systems, chemical processing equipment, and hydraulics. Typically, this type of material is used in the making of seals, gaskets, stem valves, wear and slide-machined parts, various fixtures, manifolds and pump components, and high temperature steam seals. It’s most often the choice of material for caustic fluid handling valves and fittings.
Keeping food safe is a major concern at busy restaurants. One key is to keep the kitchen and all surfaces clean and sanitized. This includes all employees washing hands regularly, cleaning all surfaces and having food safe cutting stations. At the hub of all the food preparation is the cutting surfaces used to cut food. NSF and FDA have guidelines for keeping food preparation areas clean, and one main component is the cutting board. At home, most people cut some food for dinner and then scrub the cutting board they used before putting it away. In busy restaurants the cutting boards are used constantly throughout the day. During the slow times, kitchen staff takes time to clean. Industrial Plastic Supply, Inc. is proud to supply the premium certified HDPE materials designed for restaurant cutting surfaces.
Choose The Proper Cutting Board Material
It is critical to keep hot food safe, and to maintain a clean kitchen. We provide a wide range of sizes, shapes and can include a waste cutout to match your needs. Our most popular cutting board materials are .500 (1/2″) and 1.00″ thick certified HDPE sheet material. We stock this in smooth and textured 2 sided. We also stock the colored cutting board that some restaurants prefer; these include: Yellow (used for chicken), Red (for red meat), Green (for produce) and Tan (for cooked meats). For busy kitchens we offer a auto-replacement program, so you can receive the cutting board replacements on your schedule.

In a previous post, we explored the advantages of Sabic Ultem™, the trademarked name for a special type of high-performance plastic that is often the go-to choice for any industry in need of exceptional physical properties in a thermoplastic. With Ultem™ polyetherimide resins, this type of plastic can retain its mechanical properties even at extremely high temperatures, which is especially important in applications that require good structural integrity under harsh conditions–aerospace and automotive applications for example.
Why is ULTEM™ so popular?
This material is known for its excellent mechanical properties, dimensional stability, as well as chemical and temperature resistance. Because of these properties, Ultem™ has been used widely and with success in many different industries, such as aerospace, automotive, consumer goods, medical equipment, electronics, and industrial equipment. There are, however, a few disadvantages to keep in mind when deciding whether or not to use Ultem™ for your manufacturing project.

A few disadvantages of using ULTEM™
Also, the polyetherimide thermoplastic can be vulnerable to stress cracking if exposed to polar chlorinated solvents. This can restrict its use in certain applications.
In addition, while Ultem™ is a very high performance thermoplastic, it does tend to be more expensive compared to similar materials and can be difficult to process due to its high melting point and viscosity. For optimal results, you may need to use specialized equipment or work with someone specialized in working with this thermoplastic, which could drive up production costs even more. If the material is not properly controlled during manufacturing, Ultem™ plastic parts can experience surface defects or cracks as well as dimensional instability. If large amounts of material are removed during machining, parts should be annealed after production to prevent warp and twist. Proper quality control needs to be in place to avoid these problems.
