Product Description
Expanded PTFE Joint Sealant Tape – Versatile, Self‑Adhesive Sealing for Any Flange
Kaxite Sealing is a leading China-based manufacturer and supplier of expanded PTFE joint sealant tape (Model KXT 1810) – a 100% pure expanded PTFE gasket material with a self‑adhesive backing for quick and reliable installation. Through a unique manufacturing process, PTFE is converted into a micro‑porous, fibrous structure that delivers an unmatched combination of chemical inertness, high compressibility, and excellent sealing performance. This tape conforms to irregular, damaged, or out‑of‑parallel flange faces, making it the ideal sealing solution for glass‑lined equipment, plastic flanges, heat exchangers, pumps, and compressors – even where traditional gaskets fail.
As a trusted factory direct supplier in China, Kaxite offers custom widths and thicknesses, FDA‑compliant grades, and competitive wholesale pricing. Request your price list and free sample →
