Glass fiber felt is the glass fiber cut into a certain length, through the division of silk, velvet, needles and other processes made of insulation, heat insulation, fire protection, noise reduction, air purification and other properties of the senior felt.

Features of glass fiber felt:

1. Good heat break: according to the physical principle, there are many air holes in the interior of excellent heat break materials with small heat conduction rate of gas.The glass fiber needled cotton has numerous fine gases and the fibers are irregularly arranged. It is an excellent thermal insulation material with a thermal conductivity coefficient of 0.2-0.040 kcal/ MHR.

2. No combustion: the main component of glass fiber is silicified (more than 50%), with non-combustibility, no deformation, no brittlement, and high temperature resistance up to 7000C;

3. Good sound absorption rate: when sound waves enter the glass fiber cotton, the phase energy will be inhaled in large quantity due to the friction with the fiber and different air holes of different sizes.Generally speaking, the sound absorption rate is over 90%, which is a good talent for preventing noise interference.

4. High insulation: glass fiber can withstand high temperature, good mechanical properties and high chemical stability. It is the best insulating material.

5. High corrosion resistance: glass fiber is not afraid of strong acid and alkali, and will not reduce its functional characteristics for a long time.

6. Good recovery: the glass fiber contains numerous fixed air holes and has excellent recovery.Not afraid of any shock, the tensile strength is more than 1.0kg.

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

8. Light weight and soft: compared with other heat insulation materials, the glass fiber needle felt has the lightest and softest quality. If installed on the machine, its weight and vibration load can be reduced.

9. Simple construction: the size can be cut according to the customer.

Glass fiber felt USES:

1. Heat preservation of various heat source (coal, electricity, oil and gas) high temperature equipment and central air-conditioning pipeline;

2. Used for various heat insulation and fire prevention materials;

3. Sealing, sound absorption, filtering and insulation materials for special places;

4. Heat preservation of various heat transfer and heat storage devices;

5. Sound insulation, insulation and heat resistance for vehicles, ships and aircraft;

6. Sound insulation for the inner core of auto and motorcycle muffler and noise elimination of engine;

7. Heat insulation between sandwich layers of colored steel plates and wooden buildings;

8. Thermal and chemical pipeline insulation, thermal insulation better than general insulation materials;

9. Heat insulation and insulation of wall panels of household appliances in air conditioners, refrigerators, microwave ovens and dishwashers;

10. Other places that need heat preservation, heat insulation, fire prevention, sound absorption and insulation.
