Modified PTFE Gasket Sheet, it is a structured PTFE gasket sheet. Some inorganic elements can modify creep disadvantages of pure PTFE.
Because of filler characteristic, we often recomend material as following working condition.
Hollow-Glass-Micro-Spheres with PTFE, often designing joint sealing for fragile or glass lined flanges, replacing PTFE envelope gaskets. It is not recommended for either strong or hot caustic service.
Barium Sulphate with PTFE, it is suitable for strong caustic fluids, including concentrated acids and general chemical media
Synthetic Silica with PTFE, it is suitable for highly concentrated acids service. Is also used for a general gasket service because it can handle a wide range of applications including mild caustic sealing solutions
