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. PTFE is a tough fluorocarbon coating, rendering it resistant to hot and cold corrosive chemicals and high temperatures. It also offers strong electricity insulation and doesn’t absorb water.

At Hylite, we have the infrastructure, resources, and manpower to help you get suitable PTFE coatings done on all kinds of applications. Regards of the industry, PTFE coatings are required everywhere. Whether it be in the automotive sector, power and energy, healthcare and pharmaceuticals, engineering, etc, PTFE coatings can infuse life and improved functionality and performance in pipes, valves, cabling materials, and much more.

It is because of PTFE’s many properties that it has been around and continues to a trending practice across industries. No wonder then that PTFE coating services are one of the most in-demand services on our menu..Our PTFE coating services are widely recognized in Mumbai and nationwide

Fun fact: History tells us that PTFE was discovered in the 1930s but it did not get patented before 1941 after which it transformed into a trademark as Teflon® in 1945.

XYLAN INDUSTRIAL

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.

Xylan

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.

CoF as low as 0.02

Weather resistance: against sunlight, salt water and road chemicals

Wide color range: color-code your product

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

Wear resistance

even under extreme pressures

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

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

Corrosion and chemical resistance in most environments

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

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

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

WE BUILD THINGS DIFFERENTLY

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 & there are many advantages associated with PTFE coating. We give a glimpse of some of them that will convince you about PTFE coatings usefulness and popularity:

A PTFE coating on an object or appliance inherently give it a non-stick quality. As a result, no hot or cold substances will be able to ‘stick around’ thus offering you ease in cleaning and maintenance. Now, you know why most modern kitchenware is equipped with PTFE coatings. Not just that, even automotive, aerospace, packaging, etc, are some of the industries where PTFE coatings are a way of life.
Surfaces coated with PTFE will resistant to wetness and it is a trait that aids in the cleaning process. Because of the PTFE coating, surfaces become hydrophobic and oleophobic.
Surfaces with PTFE coatings experience high resistance to extreme temperatures – hold and cost. Appliances can remain stable at advanced temperatures of up to 260°C and -270°C.
PTFE coatings cause surfaces and applications to develop a high threshold against friction and abrasion.
Anti-corrosion and chemical resistance properties.
Has high improved electrical strengths including a low dissipation factor, high surface resistivity, insulation, and high dielectric strength.

Pharmaceuticals

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.

Automotive

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.

Cryogenic

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.

After we get some information from you, we’ll set up a time to discuss your project in further detail.
