How Fluoropolymers Are Used In The Automotive Industry


Fluoropolymers play a surprising part in assisting automotive part manufacturers. They help them in meeting regulatory agencies’ requirements for modern fuel systems if you’re fascinated by cars and the nitty-gritty of how they work.

Fluoropolymers in the automotive industry enable chemical and temperature-resistant seals in the fuel systems. The use of a fluoropolymer tubing seal can shield automotive components from harmful chemicals and high temperatures, which could otherwise compromise the vehicle’s performance. It is often used by the body parts manufacturers as well as the led strip lights manufacturer if added to the vehicle. 

In this post, we will learn some important aspects of how fluoropolymers are used in the car industry.

Products Made From Fluoropolymers In Automobiles

The following fluoroplastic products by some top ptfe parts manufacturers find widespread use in the automotive industry. Their applications range from fluid delivery to coatings and sealings, temperature and level detection, and emission testing.

1. PTFE tube

As far as fluoropolymers go, PTFE tubing has the best price-to-performance ratio, with its non-stick, low friction, chemical, and electrical resistance all topping the list. More details can be found by reading up on PTFE Tubing and its uses.

2. Filled Tubing

It is possible to improve the insulation and wear resistance of fluoroplastic tubing by adding additional fillers. Fluoropolymers can be made more wear and conductivity resistant and lubricious by mixing in a filler. 

3. FEP And PTFE Heat Shrink Sleeving

For applications requiring high temperature, chemical, solvent, and UV light resistance, fluoroplastic heat shrink sleeving is the only option. It is possible to use heat shrink tubing in a wide range of applications because of its wide range of shrink ratios and working temperatures. 

4. Bags Made Of Tedlar For Gas Sampling

Tedlar gas sample bags are ideal for testing gas emissions. In addition to being durable and cost-effective, they won’t contaminate the gas sample and can easily be re-cleaned for subsequent use. Additionally, they are available in a variety of sizes and can be customized to meet specific needs. 

5. Bags Of FEP Gas Samples

FEP gas sample bags are the ideal choice for low contamination and ease of cleaning when sampling gases, odors, and emissions at parts-per-million (PPM) concentrations. They are also available in a wide range of sizes and can be tailored to meet specific needs. 

6. Thermowells And Probes With Encapsulation

Fluoropolymers provide a non-stick, chemically inert coating for encapsulating components at high temperatures. Some of the most inert materials on the planet, including FEP, PFA, and PTFE, are extremely resistant to heat. 

Fluoroplastics are ideal materials for automotive sensor protection in applications requiring temperature and level detection. 

Teflon Fluoropolymers In Automotive Industry

  • Internal shift seal rings, head gaskets, O2 sensor hermetic seals, A/C piston rings, and valve stem seals are all examples of powertrain components.
  • Oxygen sensors, throttle body injection (TBI), heated seats, brake sensors, and transmissions’ convoluted wire harnesses, radar sensors used for blind spot detection, anti-lock braking system (ABS) wires and control unit and sensor ventilation, exterior lighting venting, and automatic braking are all included in the car’s electric systems.
  • Brakes systems with ABS interconnect hoses, impulse hoses at the wheel, wear indicators for brake pads, coatings for brake shims, and clips are also products of fluoropolymers.
  • Onboard diagnostics (OBD) sensors, as well as seals and fuel lines, are included in the fuel system.
  • Everything from the power window vents to door hinge bushing sleeves to the clutch and brake pedal pivots to the protective fabrics and coated weather stripping found both inside and outside of the vehicle
  • Shock absorber piston seals,  steering assist pump piston rings, stabilizer bar bushings, steering ball joint inserts, and axle venting are included in the chassis.

Fluoroplastics’ Advantages For The Automobile Industry

PFA, FEP, and PTFE are some of the most common elements that can all be used in automotive applications because of their various special properties. Below are some of the top benefits you might not know:

  • Tensile strength and high working pressure resistance are mechanical properties.
  • Electrical conductivity, such as high dielectric strength and resistance to electric current.
  • Thermal ability to withstand extremes of temperature.
  • Resistant to chemicals and solvents in their entirety.
  • Anti-corrosive and weather-resistant, environmentally friendly. 

As a result, the following properties of PTFE, FEP, PFA, and PVDF make them ideal for automotive use:

  • Electrical, chemical, and extreme temperature insulation
  • The lifespan of components has been increased as a result
  • Increased productivity while also enhancing security
  • This product protects against weather and environmental conditions
  • Corrosion prevention measures


Ranging from pond filter system to food and drinks and the automotive industry, fluoropolymers are used everywhere. Automotive manufacturers add value to suppliers and customers by developing car components that can withstand higher temperatures and corrosion better than the competition. Cars are better protected from the inside and out with Teflon products. 

This allows drivers to enjoy a more enjoyable experience behind the wheel. Fluoropolymers have low-friction surfaces, improve efficiency and longevity, and allow car parts to withstand harsh environments.
