< : >Polytetrafluoroethylene sandwich gaskets are composed of soft gaskets such as asbestos rubber sheets or non-asbestos boards and polytetrafluoroethylene coating sheets, type (cut type ) PTFE sandwich gaskets are machined from PTFE plates. Type (folding type) PTFE sandwich gaskets are made of PTFE tapes that are wrapped and then heated and bonded. They have both excellent corrosion resistance and good The compression rebound rate is widely used in the sealing of various strong acids, strong alkali, strong oxidizing chlorine gas and media that are not allowed to pollute. Usually suitable for medium and low pressure parts.
