Types of PTFE Gaskets We Manufacture
Goa Polymer is a leading PTFE Gasket Manufacturers in India. We are involved in the manufacturing of kinds of Gaskets-
- Pure PTFE Gaskets: They are made of pure PTFE. They are highly used in the chemical processing, pharmaceuticals, food and beverage industries, and other environments where chemicals are used. Because they are Excellent chemical resistance, excellent temperature resistance as well as non-stick properties.
- Glass-Filled PTFE-Gaskets: This gasket is enhanced by glass fibre. They have better mechanical strength, rigidity, and wear resistance as compared to standard gaskets. They are perfect to use in high-pressure and high-temperature applications. Chemical and petrochemical industries use them often. Because they have excellent mechanical strength, better wear resistance, and increased rigidity.
- Carbon-Filled PTFE-Gaskets: These gaskets are enhanced by the carbon particles. They have enhanced wear resistance, thermal conductivity, and electrical conductivity. They are highly used in the automotive, aerospace, and electronics industries. Because they have high friction, excellent wear resistance, thermal and electrical conductivity, and increased strength.
- Soft PTFE Gaskets: These gaskets are made from specially formulated PTFE. They are more pliable compared to standard PTFE. Their softness gives a better and tighter seal. They are perfect to use in sealing flanges with minor surfaces where high flexibility is required.

FAQ’s
What is a PTFE gasket?
A PTFE gasket is a sealing component made from polytetrafluoroethylene (PTFE), a fluoropolymer known for its chemical resistance, thermal stability, and low friction properties. It is used to create a tight seal between two surfaces, preventing leaks and ensuring optimal performance in various industrial applications.
Why choose PTFE gaskets over other materials?
PTFE gaskets are preferred for their exceptional chemical resistance, high-temperature tolerance, and low friction characteristics. Unlike other materials, PTFE does not react with most chemicals, maintains its integrity at high temperatures, and provides a reliable seal in extreme conditions.
What industries use PTFE gaskets?
PTFE gaskets are used in a variety of industries, including chemical processing, pharmaceuticals, food and beverage, and oil and gas. Their versatility and durability make them suitable for applications where resistance to harsh chemicals and high temperatures is required.
How are PTFE gaskets manufactured?
PTFE gaskets are typically manufactured through processes such as extrusion, compression molding, or die-cutting. The PTFE material is shaped into gaskets of various sizes and forms, depending on the specific requirements of the application and the design specifications.
Can PTFE gaskets be customized?
Yes, PTFE gaskets can be customized to meet specific requirements. Customizations can include varying sizes, shapes, thicknesses, and even material formulations to suit particular applications and operational conditions.
