20mm E-glass Sound Insulation Fiberglass Needle Mat For Muffler And Silencers

Process of e-glass fiber glass needled mat is mechanically needling bonding glass fibers. Chopping in 3cm to 8cm glass fibers by cutting machine. And then puffed, carded and continuously needled by thousands of special needles. It is produced from a well-controlled types of long textile fiber glass to ensure mechanical bonding with no other binders. The needle mat has great insulation application for exposure under high temperatures. It also can be used for thermal insulatio, soumd insulation, filtration applications. Besides, this needle mat can be used as fireproof wadding materials, moto mufflers, gun mufflers and elevator sound insulation materials.

Density of fiber glass needle mat can be 100-300kg/m3. Available thickness is 3mm-25mm. Width can be 240cm max. So 100cm, 120cm, 240cm are very common width with more economical price and less delivery time. The working temperature of this e-glass fiber glass needle mat is below 800℃(1472℉).

Data Sheet Of Mat

Heat InsulationNoise Isolation



Noise Isolation Coefficien (kal/mhr°C)



Noise Isolation Coefficient

Excellent noise isolation capacity;

Absorbs noise and also vibration.




1. Thermal Insulation

E-glass needle mat can withstand high temperature of 700, 850 and 1000 degree Celsius

2. Specification

Needle mat can be cut into different thickness (3mm~25mm) according to the requirements of customers.

2. Fire Resistance Material

The main element of glass fiber is non-combustible and will not shrink under high temperature

3. Excellent Sound Insulation

When the sound wave enters the glass fiber mat, its energy will be absorbed by the mat because of the friction between glass fibers and different sizes of air space. The sound absorbing coefficient of the glass fiber mat is higher than 90%.

4. Corrosion Resistance

Glass fiber materials are chemical resistant. It can resist corrosion of strong acid and alkali.

5. Light weight and Soft Material

Compared with the other heat insulation materials, fiberglass fabric and fiberglass mat are the lightest and softest material. If installed on machinery, the needle mat can help reduce the burden of weight and vibration.
