  • Expanded PTFE Gasket

    Expanded PTFE Gasket

    Kaxite Seals is a China-based expanded PTFE gasket manufacturer producing gaskets from 100% virgin ePTFE sheet. The material is soft, twistable and bendable, with excellent anti-creep and cold-flow resistance — even under alternating temperature and pressure, sealing performance stays stable. It works from −268 °C to +280 °C, handles liquid pressure up to 8 MPa, and complies with FDA 21 CFR 177.1550. It is the practical choice for damaged flanges, irregular flanges and glass-ceramic flanges that a standard gasket cannot seal. Custom sizes, die-cut shapes, OEM private-label packaging and flexible MOQ are available for B2B buyers. Send your drawing, flange size, thickness and quantity for a bulk quotation.
  • PTFE Porous Membrane

    PTFE Porous Membrane

    Kaxite Seals is a China-based PTFE porous membrane manufacturer producing hydrophobic, biaxially oriented ePTFE membrane from 100% virgin PTFE resin.

  • Why is PTFE so expensive?

    Processing PTFE is difficult and expensive, and this is because of its rigid polymer chain structure.

  • What is the difference between virgin and expanded PTFE?

    Both PTFE and Expanded PTFE have good chemical resistance. Additionally, Expanded PTFE has better creep resistance and cold flow. Some of the key characteristics of PTFE are as follows: It can perform well in environments with temperatures as high as 260 Degree Celsius.

  • Are there different grades of PTFE?

    PTFE is available in many different Grades as Virgin PTFE, Chemically Modified PTFE, Carbon Filled PTFE, Glass Filed PTFE, Carbon / Coke Filled PTFE, Graphite Filled PTFE, Bronze Filled PTFE, Bronze + Molybdenum Disulphide Filled PTFE, Aluminum Oxide Filled PTFE, Calcium Fluoride Filled PTFE, Stainless Steel Filled ...

  • What is the difference between PTFE and modified PTFE?

    Modified PTFE offers many advantages over PTFE. Lower deformation under load, better fatigue performance, easier to weld, better transparency, higher elongation and higher dielectric strength. Modified PTFE, like PTFE, has excellent chemical resistance and a very low coefficient of friction.

  • Does PTFE expand when heated?

    In this example, when the part is heated from 77°F/25°C to 392°F/200°C, at the upper end of the temperature range the PTFE component will grow approximately 24 mm longer than the mating metal part.

  • What is an expanded PTFE sheet?

    The expanded PTFE sheet is made from 100 percent virgin PTFE and is exceptionally compressible. It is a food-safe product with great chemical resistance, making it a preferred sealing material in the food, beverage, and pharmaceutical sectors.
