PTFE Coated Fiberglass Sewing Thread is primarily used as a perfect sewing material for detachable thermal covers and any other special-shaped wraps where protection against heat and moisture is necessary. Made of 100% ultra fine fiberglass rings and coated with non-adhesive PTFE, our Fiberglass Sewing Thread provides excellent heat resistant, insulating, fireproof and anti-aging performance.
Good thermal insulation and abrasion resistant performance make PTFE Coated Fiberglass Sewing Thread withstand continuous exposure to 280℃(536℉) and instantaneous exposure to 600℃(1100℉) that is excellent for automotive, industrial, and marine applications.
