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℉).

Feature
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.
