Characteristics of Glass Fiber Needle Felt:
1. Heat Resistance and Specification
It can resist high temperature of 700o C, 850o C and 1000o C and be cut into different thickness (3mm~100mm) according to the requirements of customers.

2. Excellent Heat Insulation
According to physical principle, the thermal conductivity rate of gas is smaller than that of solid.? For excellent heat insulation materials, there should be many air pockets inside the materials. As an excellent heat insulation material, the glass fiber cotton has innumerable tiny air pockets, and its fibers are arranged irregularly with a thermal conductivity coefficient between 0.2~0.040 kcal/mhro C

3. Noncombustible Material
The main element of glass fiber is silicide (over 50%) which is noncombustible and will not deform or embrittle even under high temperature for 3 consecutive hours.

4. Good Sound Absorption
When the sound wave enters the glass fiber cotton, its energy will be absorbed by the cotton due to the friction between fibers and different sizes of air pockets.? Generally speaking, the sound absorbing coefficient of the glass fiber cotton is higher than 90%. Therefore, it is a good material for preventing the interference of noise.

5. High Insulation
Glass fiber is the best insulation material because it is able to resist high temperature and has good mechanical property and high chemical stability.

6. Anticorrosion
Glass fiber can resist corrosion of strong acid and alkali. Its functions will not be diminished after long-term use.

7. Good Restoring Force
Glass fiber contains countless air pockets, so it has excellent restoring force to resist any impact and vibration with a tensile strength over 1.0 kg.

8. Low Moisture Absorption Rate
Its moisture absorption rate is usually close to zero.

9. Lightweight and Soft Material
In comparison with the other heat insulation materials, glass fiber products are the lightest and softest material.? If installed on machinery, it can help reduce the burden of weight and vibration.

10. Simple and Easy Construction
It is simple and easy to use glass fiber for all kinds of thermal insulation, heat insulation, r
