Properties of PTFE Coated Fiberglass Fabric

Introduction

In many industrial applications, materials must endure high temperatures, resist chemical attack, and provide a non-stick surface. Standard fabrics often degrade under such conditions, leading to frequent replacements and production delays.

PTFE Coated Fiberglass Fabric solves these challenges. It combines the mechanical strength of woven fiberglass with the non-stick, chemical-resistant, and high-temperature properties of PTFE. This versatile material is widely used in food processing, packaging, aerospace, electronics, and chemical manufacturing for conveyor belts, release sheets, insulation wraps, and sealing applications.

1. Key Features

Excellent Non-Stick Surface – PTFE coating prevents adhesion of resins, adhesives, and food products.

High-Temperature Resistance – Continuous service up to 260°C, short-term up to 300°C.

Outstanding Chemical Resistance – Resists almost all chemicals, including acids, alkalis, and solvents.

High Mechanical Strength – Fiberglass substrate provides excellent tensile and tear strength.

Low Coefficient of Friction – Smooth surface (0.05–0.10) improves material flow.

Excellent Electrical Insulation – High dielectric strength for electrical applications.
