PTFE Coated Kevlar (Aramid) Fabric
1. Product Overview
PTFE coated Kevlar (aramid) fabric is an advanced industrial composite engineered from a high-tensile woven aramid (Kevlar) substrate impregnated and sintered with polytetrafluoroethylene (PTFE) dispersion. Combining the exceptional mechanical strength, puncture resistance, and flex-fatigue endurance of aramid fibers with the non-stick, low-friction, and chemical-inert properties of fluoropolymers, this material provides superior durability under severe mechanical stress and thermal cycling compared to standard fiberglass-based fabrics.
