Glass fiber needle felt characteristics

2022-10-24

Glassfiber needle-punched felt is a kind of filter material with reasonable structure and good performance. It can be used for sound insulation, sound absorption, shock absorption, flame retardant, etc. in the automotive industry. Fiber needle felt has been widely used in flue gas purification in carbon black, steel, non-ferrous metals, chemical industry, incineration and other industries because of its excellent performance;

Share the characteristics of fiberglass felt below

1. Good thermal insulation

According to physical principles, the thermal conductivity of gas is small, and there are many air pockets inside the insulating material. The glass fiber needle-punched cotton has countless tiny gases, and the fibers are irregularly arranged. between c.

2. Flame retardancy

Non-combustible The main component of glass fiber is silicide (more than 50%), which is non-flammable, non-deformed, non-brittle, and resistant to high temperature up to 7000C

3. Good sound absorption rate

When the sound wave penetrates into the glass fiber wool, the energy will be inhaled in large quantities due to friction with the fibers and air pockets of different sizes. Generally speaking, the sound absorption rate is as high as 90% or more, which is a good talent to prevent noise interference.

4. High insulation

Glassfiber can withstand high temperature, has good mechanical properties, and has high chemical stability, and is an insulating material.

5. High corrosion resistance

Glassfiber is not afraid of strong acid and alkali, and its functional properties will not be reduced for a long time.

6. Good responsiveness

The fiberglass contains numerous fixed air pockets and is extremely resilient. Not afraid of any shock and vibration, the tensile strength is above 1.0kg.

7. Low moisture absorption rate

Moisture absorption is usually close to zero.

8. Light weight and soft

Compared with other thermal insulation materials, fiberglass needled felt is the lightest and most flexible. If it is installed on a machine, it can reduce its weight and vibration load.

9. Simple construction

Size can be cut according to customers.
