concrete fiberglass E-glass chopped strands

Glass Fiber chopped strands for concrete can improve the permeability, impact with resistance and toughness and endurance of concrete. It (glass yarn) (Fiber Glass)  (Fiberglass cloth)  is mainly used in cement, gypsum board, plastics, composite products, etc, and other construction projects ,and so on.

1. Good thermal insulation: According to physical principles, the thermal conductivity of gas is small, and there are many air pockets inside excellent thermal insulation materials. Glass fiber 

needle-punched cotton has countless fine gases and the fibers are irregularly arranged. It is an excellent thermal insulation material with a thermal conductivity with  coefficient of 0.2 to 0.040kcal/mhr. between c;

2. Will not burn: The main component of glass fiber(chopped fibres,chopped fiberglass,chopped fiber composites) is silicide (accounting for more than 50%), which is non-flammable, has no deformation, no embrittlement, and can withstand high temperatures up to 700°C;

4. High insulation: Glass fiber can bear high temperatures, and has high chemical of stability;

5. High deep etch   resistance: Glass fiber is not afraid of strong acid and alkali, and its functional properties will not be reduced for a long time;

6. Good restorability: Glass fiber contains numerous fixed air pockets and has excellent restorability. Not afraid of any impact or vibration, the tensile strength is above 1.0kg.

7. Low moisture absorption rate: The moisture absorption rate is usually close to zero.

8. Light weight and soft: Compared with other insulation materials, fiberglass needle felt is the lightest and softest. If installed on machinery, it can reduce its weight and vibration load.
