Glass insulation material, alkali free fiberglass needle felt, fiberglass cotton

Glass fiber needle felt can be used for sound insulation, absorption, shock absorption, flame retardancy, etc. in the automotive industry, mainly used in the filtration field of industry; High temperature flue gas filtration; Glass fiber needle felt is widely used in various bag filters for flue gas purification and dust recovery in industries such as carbon black, steel, non-ferrous metals, chemical industry, and incineration.

1、 Excellent characteristics

1. Good heat insulation: According to physical principles, gas has a low thermal conductivity, and excellent heat insulation materials have many air pockets inside. And glass fiber needle punched cotton has countless small gases, and the fibers are irregularly arranged, making it an excellent insulation material with a thermal conductivity coefficient of 0.2~0.040kcal/mhr. Between c;

2. The main component of non combustible glass fiber is silicide (accounting for more than 50%), which has non flammability, no deformation, no embrittlement, and high temperature resistance up to 7000C;

3. Good sound absorption rate: When sound waves invade glass fiber cotton, a large amount of energy is absorbed due to friction with fibers and air pockets 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 temperatures, has good mechanical properties, and high chemical stability, making it the best insulation material;

5. High corrosion resistance: Glass fiber is not afraid of strong acids or alkalis, and its functional characteristics will not be reduced for a long time;

6. Good resilience: Glass fiber contains numerous fixed air pockets, providing excellent resilience. Not afraid of any impact or vibration, with a tensile strength of over 1.0kg.

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

8. Lightweight: Compared with other insulation materials, fiberglass needle felt has the lightest and most flexible mass. If installed on machinery, it can reduce its weight and vibration load.

9. Easy construction: The size can be cut according to the customer's preferences.
