Fireproof Fiberglass Cloth Low Fuzz E-Glass Fabric For Composite Reinforcement

Product Introduction
Fiberglass cloth (glass fiber fabric) is a high-performance woven reinforcement material made of continuous E-glass filament yarn through precise weaving process. With stable structure, uniform mesh, less fuzz, good permeability to resin, it is the most widely used industrial base material for insulation and composite industry.

Core Advantages

• Raw material: 100% Alkali-free E-glass fiber, stable dimension, low thermal expansion
• Excellent dielectric property, perfect insulation for electronics, transformer, motor winding
• High temperature resistance, flame retardant, non-combustible
• Strong tensile strength, anti-aging, acid & alkali resistant, long service life in harsh environment
• Good soaking performance, easy to exhaust bubbles when laminating with epoxy/polyester resin
• Plain weave & twill weave in stock, width 1000mm/1200mm/customized, roll length 50m/100m

Main Applications
1. Electrical industry: Insulation wrapping for transformer, motor, cable, mica tape substrate
2. FRP composite: Boat, yacht, surfboard, tank, pipeline, FRP panel reinforcement & repair
3. Thermal insulation: Steam pipe wrapping, high temperature pipeline anti-corrosion & heat preservation
4. Construction: Wall crack resistance, roof reinforcement, mold making
5. Auto & machinery: Exhaust heat shield, engine insulation lining
