Characteristics of Glass Fiber Needle felt:

1.Heat Resistance and Specification
It can resist high temperature of 700, 850 and 1000 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/mhr

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, refractory and sound absorbing engineering or products.

11. Temperature can this filter working continuous 220C Degree, instant 260C Degree.
12. Heat shrink rate less than 0.5% at working temperature, rate less than 1% at temperature 300C Degree.
13. Good character of wear and tear resistance.
14. Easy usage when clear the dust with its slippery surface.
15. High air permeability: Its filter material is a smooth cylinder, the volume is small, dust removing easy and tearing resistance excellent. All these characters make its high filter efficiency, and can be for reverse blowing, revolving back blowing, and pulse dust removal.

Application:
1. Building: for roofing, flooring and walls thermal and acoustical insulation, guarantee the building object be the energy-saving type.
2. Ship and automobiles: replace the structure and shell body of the metal and pure plastic wooden materials, reduce the needed driving force, save energy, extend the life.
3. Heat insulation for industry equipment, parts and duct and household electrical appliances
4. Aviation and space flight: thermal and acoustic insulation for thin panel and nail-board by fire-proofing fabrics, used for the thermal insulation and sound absorption of engine system, Absorbing noises and purifies the tail gas.
5. Traffic: widely used in railway, highway, sports ground, water construction, environment-protection project, would shorten the construction period, extend the using life.
