The peek pipe produced by continuous extrusion process solves the technical problems of limited product height in molding process and easy internal shrinkage hole in injection molding process. At the same time, it reduces material loss and machining cost. It can be processed into ring parts such as sealing ring, piston ring, wear-resistant shaft sleeve and valve seat. It is widely used in petrochemical, electronic semiconductor and other industries.

Parts with long-term service temperature above 300 ℃ and short-term service temperature of 400 ~ 450 ℃.
