Fiberglass Needle Blanket

Fiberglass Needle Blanket

1.SiO2≥96% 2.Soft point nearly 1700℃, long-period service at 900℃ 3.Low thermal conductivity 4.Good chemical stability 5.Good electrical insulation 6.Low thermal shrinkage 7.Non-asbestos product without pollution 8.Good process performance

Fiberglass needle blanket

High Silica Fiberglass Needle Mat is made from high silica fiberglass chopped strands through carding and needling process. The silica fibers randomly distribute and wind together during needling process. Silica fiberglass needle mat possesses 3D structure and highly pore structure with high void content.

Silica Fiberglass Needle Mats with low thermal conductivity, high heat resistance and good acoustic resistance are excellent high temperature insulators. It can be used over long periods without losing the properties and without melting and vaporising at temperatures of up to 1000ºC, and short-time exposure up to 1300°C.


1. Filtration material: high temperature gas and liquid metallurgy industry

2. Thermal resistance material: aircraft and aerospace industries, and other electro- and chemical industries industry

3. Acoustic material: thermal and acoustic insulation applications in automotive and exhaust systems.

Product Features:

Health safety: no toxic gases emit, no carcinogenic fiber

Low thermal conductivity, high electrical insulation properties at elevated temperature

High heat resistance as high as 1000℃
