Fiberglass Yarn – Superior Flexibility, Anti-Friction
Fiberglass yarn is made of glass spheres which are melted at high temperature in platinum-rhodium bushing and cooled rapidly. Finished products are available in continuous filaments and chopped strands for various fiberglass fabric or other GRP reinforced products. Continuous fiberglass filaments can be divided into texturized yarn, direct roving yarn, piled yarn, single yarn, twisted yarns.
Fiberglass yarn is such a versatile material for industry, construction, water treatment, communal facilities, electric power industry, fire proofing system and so on. Whether for reinforcement, filtration or insulation, it is affordable since its excellent resistance to pressure and extreme conditions. Sometimes, it is alternative to asbestos products.


What make the product sell well?
- Close winding and convenient unwinding.
- Light weight, high tensile strength.
- Smooth finishing and uniform color.
- Low thermal conductivity coefficient.
- Fireproof, mouldproof and mothproof.
- Good electrical insulation.
- Low static, excellent mechanical properties.
