PTFE Bronze 40%

Overview of PTFE Bronze 40%

PTFE bronze 40% material is a type of Polytetrafluoroethylene. The PTFE itself stands for Polytetrafluoroethylene. However, the PTFE bronze 40% material slightly differs from the standard or virgin Polytetrafluoroethylene in composition. It consists of 40% bronze with 60% of virgin Polytetrafluoroethylene. PTFE bronze is used for the production of industrial sealing solutions due to its properties like high dimensional stability, comprehensive strength, hardness, etc. This engineered thermoplastic is chosen over virgin Polytetrafluoroethylene whenever durable application of industrial components like seals, gaskets, etc at high temperature is demanded. SSP Seals offers seals and gaskets made from PTFE bronze 40%.

Benefits of PTFE Bronze 40% Seals

We regularly produce bronze filled PTFE seals for our clients across industries. The following benefits of PTFE bronze 40% have made this thermoplastic highly popular.

  • Bronze filled PTFE is inert in nature, therefore these PTFE bronze seals can be used in chemical-exposed applications. These seals are beneficial for applications including oils, lubricants, chemicals, etc.
  • These seals can tolerate both cryogenic and extreme temperatures. The operating temperature range for these seals is -200°C to +260°C.
  • These seals offer a low coefficient of friction, therefore they minimize frictional damage. This results in the reduction of frictional wear and enhances the life expectancy of these seals.
  • Bronze filled PTFE is absolutely non-toxic, and is safe for users and the environment.
  • The material offers great deformation strength therefore the dimensional stability of these seals is excellent.
  • These seals offer good thermal conductivity, therefore thermal distribution is optimum in these seals.
