What is PTFE Coating

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. Being hydrophobic, non-wetting, high density and resistant to high temperatures, PTFE is an incredibly versatile material with a wide variety of applications, though it’s perhaps best-known for its non-stick properties.



The first brand offered by Whitford, Xylan® is the benchmark of our line of industrial coatings; used to identify our low-friction, wear-resistant composites of fluoropolymers and reinforcing binder resins. The Xylan industrial family of coatings (Xylan, Xylan XLR and Xylan XLR HB) are extreme performance coatings – working under heavy loads, at high temperatures, in chemical and corrosive environments.



First and foremost, Xylan coatings are dry-film lubricants combined in a matrix with high-temperature organic polymers resulting in “plastic alloys” formulated to provide unique and desirable properties.

Low friction:
CoF as low as 0.02

Wear resistance
even under extreme pressures

Corrosion and chemical resistance in most environments

Weather resistance: against sunlight, salt water and road chemicals

Wide temperature operating range: from -420°F to +550°F (-250°C to 285°C)

Flexible curing schedule: ambient to 750°F (400°C)

Wide color range: color-code your product

Pliability: Many Xylan coatings will bend freely and repeatedly without breaking

Machinability: apply multiple coats of Xylan coating (most formulations) and mill to specification

Excellent adhesion: to most metals, plastics, ceramics, wood, even to itself (most formulations)

Xylan XLR (Xtra-Long Release)

Developed specifically to provide dry-film release with exceptional resistance to permeation, Xylan XLR is a heat-resistant coating offering greatly increased release-life as well as a reduced tendency for formed parts to stick to the mold.

A two-coat, waterborne system
A unique, super-high release topcoat with a lightly reinforced primer suitable for a variety of substrates including carbon steel.
A more heavily reinforced primer is available for applications where a lot of abrasion resistance is required
Is food-safe and can be used at temperatures up to 500°F/260°C
Improved hardness
Superior smoothness/higher gloss
Dramatic cost-savings due to reduced need to re-coat

Xylan XLR HB (High-Build)

Better, longer-lasting release specifically for use on industrial bakeware. Xylan XLR HB combines two of Whitford’s proprietary technologies: Eterna (XLR) and Hi-Build Liquid (HB).

Doubles the film thickness of Xylan XLR – achieving 50-70 microns
Outstanding high-release liquid coating matching the typical DFT of powder coating in one cure cycle.
Improved longevity of release in bakeware applications – additional value for the end user
In some applications replaces two topcoats of XLR – additional value for the applicator

Applications – Benefits of
PTFE and where it is used

There are numerous ways PTFE can be used. Here are some of the most common industries that use this type of material:


PTFE coatings are important in the pharmaceutical industry because they provide over braid seals and strength and ease when cleaning and purging the system. The pharmaceutical industry has very high standards for all materials used within it, and PTFE meets or exceeds these high standards.


Many vehicles use PTFE components, especially in air brake systems in which constructions made of over-braided hoses are needed. PTFE can stand up to some extremely high temperatures, which makes it perfect for use on the outside edge of air compressors. Also PTFE works to reduce deposits of carbon particles, so it’s extremely helpful in all types of automotive applications.


In addition to being able to withstand extremely high temperatures, it can also withstand the very low temperatures used within the cryogenics industry. This material is perfect for use in hydraulic hoses, piston rings, fuel lines, or liquid air systems.

Chemical industry

You’ll often find PTFE in hoses that are used to transfer chemicals, connectors, and lines for product interchange. Refrigeration systems and steam lines also contain PTFE. The material typically replaces corrugated, stainless steel hoses.

Aerospace industry

Within this industry, PTFE is commonly used for tubing hoses, hydraulic hoses, and fuel hoses. It’s often braided in with Kevlar for added protection. Also PTFE is commonly used in applications that require the tempering of heat, especially in water and alcohol, oil, and fuel. PTFE is commonly found in pneumatic and hydraulic systems that are commonly used within this industry.

How is PTFE Xylan Coating Applied

As you can see, PTFE is a very versatile material that can be used in numerous types of industries. If you think it will work for your project, you should check with a professional to learn more about the fine details and characteristics of this material.
