Flange Gasket

PTFE Teflon Gasket

PTFE Teflon Gasket has strong corrosion resistance and friction-resistance,By adding filler such as glass fiber,carbon fiber,copper powder,graphite,asbestos,MOS2,AL2O3,carbon powder,ceramic fiber,metal powder,polyamide,PS,the hardness,compression strength and abrasion resistance of the products is improved ,in addition,it will have good heat conductivity and low heat expansion coefficient.

PTFE Teflon Gasket

Features:

  1. PTFE gasket is manufactured by molding method with suspended PTFE resin.
  2. PTFE compared with other plastics, has superior properties against chemicals and temperature
  3. Excellent properties, PTFE has a wide application as a sealing material.
  4. it will take 5-8days to finished the sample .at that time we will show the sample picture to you first .
  5. Now molds can be made according to customers requirements

Filling Material

Glass Fiber: Increases compressive strength, rigidity and wear.
Reduces creep and cold flow
Minimal effect on chemical and electrical properties
Carbon: Increases compressive strength, hardness, wear, and load properties.
Good chemical resistance
Various types and amounts of carbon can be added to alter conductivity
Graphite: Reduces coefficient of friction
Reduces initial wear
Increases strength
Molybdenum Disulfide: Increases hardness, stiffness, and wear
Minimal effect on chemical and electrical properties
Bronze: Increases hardness and wear resistance
Increases dimensional stability and compressive strength
Not suitable for corrosive or electrical applications
