Heat Memory PTFE sheet

Heat Memory PTFE sheet 1.It is suitable to be a structure part that is to be expanded by external force 2.and so on

This is a special type of molded PTFE sheet with heat-memory effect. It has a special feature of recovering a forced deformation of PTFE sheet into original dimension when being heated. It is suitable to be a structure part that is to be expanded by external force and be recovered by heat, and is used as gasket, seal ring etc. in a various kind of corrosive medium. It conforms to the enterprise standard of Q/GHAD 86-2008
