PTFE High-Temperature Fabric Product Introduction


PTFE high-temperature fabric is a high-performance industrial textile woven from pure polytetrafluoroethylene (PTFE) fibers, exhibiting exceptional temperature resistance and mechanical strength after special sintering treatment. As a critical material for high-temperature environments, it is widely used in demanding applications across chemical, food processing, electronics, and other industries.

Core Characteristics
· Extreme Temperature Resistance: Stable long-term use from -70℃ to +280℃, with momentary resistance up to 320℃.
· Excellent Corrosion Resistance: Withstands highly corrosive media like 98% sulfuric acid and 50% sodium hydroxide.
· Safe & Eco-Friendly: FDA food-grade certified (21 CFR 177.1550).
· Physical Stability: Thermal shrinkage < 1.5% (tested at 260℃).
