About PTFE Natural®

The PTFE Natural® Difference

PTFE Natural® is a unique customized process and superior lubricious and robust coating in the medical device market developed by Applied Plastics to provide catheter engineers with the best performance characteristics to enable development. At Applied Plastics, we have a deep understanding of the material and how it interacts with technology solutions for customers.

Our proprietary PTFE Natural® is ideal for applications requiring heat or abrasion resistance.

With our unique ability to hold tight OD tolerances our coated mandrels are used as a critical catheter manufacturing aids ranging from tipping and welding mandrels, reflow mandrels, core wires, pull wires to lubricious coatings for stylets and guidewires for highly engineered catheter systems.

Speed is Key.

We understand the medical device markets’ need for speed and robust coatings while designing and developing products and processes. Applied Plastics holds a large volume of various diameter wire and is prepared to meet your coated OD requirements quickly. Visit our online store for more details.

PTFE Natural® is the engineers’ lubricious coating of choice when designing, developing and manufacturing advanced access, delivery and closure devices and systems.

PTFE Natural®
PTFE Natural® is a unique customized process and superior lubricious and robust coating in the medical device market developed by Applied Plastics to provide catheter engineers with the best performance characteristics to enable development and manufacturing. About PTFE Natural®.

Teflon® FEP
This nonstick coating melts and flows during baking to provide nonporous films. In addition to a low coefficient of friction, it provides excellent chemical resistance.

Teflon® PFA
Like FEP, PFA coatings melt and flow during baking to provide nonporous films. It offers the additional benefits of higher continuous temperatures (260°C, 500°F), heavier average film thickness and greater toughness.

Teflon® PTFE
This nonstick coating has the highest operating temperature of any fluoropolymer (290°C, 550°F continuous),an extremely low coefficient of friction (0.05 to 0.20), and good chemical resistance. This finish is hydrophobic and oleophobic, permitting faster and more complete clean-up.

Tefzel® ETFE
A copolymer of TFE and Ethylene that melts and flows during baking to create a nonporous film, it provides excellent chemical resistance, exceptional abrasion resistance, the highest coefficient of friction, and 3,000 v/mil dielectric strength. Standard film builds can range from 1.0 to 50+ mils, depending on product and application method.

Teflon® S
Developed for applications requiring heavy-duty service or lubrication under high pressure or velocity, this coating is formulated with special blends of fluoropolymers and other high-performance resins to improve toughness and abrasion resistance.

Halar® ECTFE
Offers superior chemical resistance, good electrical and abrasion resistance and permits heavier film builds compared to most fluorocarbon coatings.

Kynar® PVDF
Similar to ECTFE coating, PVDF exhibits a high level of mechanical strength and toughness with excellent chemical resistance over a wide temperature range.

This nonstick coating has excellent heat resistance and great cryogenic stability over a wide temperature range, is normally impervious to most chemicals, and provides high dielectric strength.

This coating provides lubrication and controlled friction, wear resistance, heat resistance, nonstick and release properties and, at the same time, can also protect from corrosion. Formulations are available to adhere to a wide range of substrates.

This nonstick coating from Chemours Teflon®‚ was specifically designed for cookware, but has also been used on rollers and for many other industrial applications.

Some of the very first thermoset powder coatings were based on epoxy resins. This group of materials offers the best chemical, corrosion and heat resistance and will not remelt when heat is applied.

This powder demonstrates an excellent mixture of impact, chemical flexibility and UV resistance and isoften considered the most universal thermoset powder chemistry.

One of the toughest plastic coatings available, it produces excellent impact and abrasion resistance. Other properties include corrosion and chemical resistance, low co-efficient of friction the the prevention of the formation of fungus.

All Substrates that can be Coated

At Applied Plastics, we can apply coatings by several methods including electrostatic spraying, electrostatic fluidized bed, conventional powder and liquid spraying, and various proprietary techniques for fine wire and hypotubes. To assure the best possible adhesion and surface finish, we employ a wide range of manual and automatic and substrate preparation techniques. From surface degreasing through final curing, our skilled technicians perform all processes at our Norwood, Massachusetts facility. And to make sure that our quality is unparalleled, we use laser micrometers that can measure thickness tolerances of ±0.0001” or better.
