PTFE Coated Sewing Thread

PTFE coated sewing thread is is a high temperature sewing thread,which manufactured from continuous filament Beta fiberglass yarns,whose operating temperature is about 540℃. The sewing thread is high temperature resistance, high strength,good flexibility and chemical resistance.The thread is completely encapsulated by a uniform layer of PTFE coating which enhances the resistance to contaminates by most acids and alkalis.
