Product Description:
Glass wool dry felt is made of quartz sand, soda ash, borax and other chemical raw materials fused into glass liquid. In the melting state, with the help of centrifugal or flame external force, blow and shake into a flocculent microfiber glass wool. The dry microfiber glass wool felt of certain specifications is formed by subsequent fiber interweaving, hot pressing curing and then longitudinal and transverse cutting.
Product features:
1.Safe, green environmental protection: white color, no impurities and any bonding agent; The fiber diameter is ultrafine, the length is uniform and the dispersion is small. No slag ball, soft feel; No health effects on humans.
2.Excellent thermal insulation and acoustic characteristics: soft fiber, large specific surface area, sound absorption, sound insulation ability. A1 grade non-combustible material, low thermal conductivity, excellent heat resistance, heat resistance, maximum operating temperature up to 600℃.
3.Stable and reliable long-term performance: fiber interweaving, excellent anti-vibration performance; Strong chemical stability, long-term use of functional properties will not decay.
4.Convenient storage and transportation construction performance: product size is regular, evenness, tensile strength, resilience, easy cutting, convenient construction.
Typical applications:
It can be used in vacuum insulation board, home appliance insulation, light steel building, roof insulation, large commercial complex villa interior installation and acoustics, HVAC/fresh air system, ship cabin body, high-speed rail aviation sandwich and other fields.
