Product Description

Soft seats/RPTFE seal are generally made of thermoplastic materials like PTFE. They're great for applications where chemical compatibility is important, and where the tightest seal is key.Based on different application,it can be added some fillers for PTFE,which not only keeps the original properties,but also enhanced the rigidity,anti-abrasion,anti-deformation,thermal conductivity,etc.,and thus improved the overall performance of PTFE.Commonly used fillers are :Glass fiber,graphite,carbon fiber,molybdenum disulfide,copper powder,Ekonol(polyphenyl ester,PEEK etc.
