Product Introduction:    Glass wool felt is a kind of glass fiber product, the manufacturing technique is glass and other raw material are sent into melt oven after crushing, and melted into molten glass in the temperature 1450C-1460C. Then the molten glass flow into the forehearth after clarified and homogenized, and is converted in to fine fiber, the fiber is sprayed with binder well-distributed and solidified in curing oven, finally be  cutted into different size of glass wool felt. According to customer’s request, kinds of foil can be coated directly on the production line, such as Al foil, craft, PVC, glass fiber cloth etc.

    According to customer’s different request ,glass wool felt can be made with below special properties.

High temperature: Using special high temperature binder, we can produce high temperature glass wool felt with max 600C. It is widely used in power plant flue, hot blast flue, steam pipeline etc, also can be used for insulation in pipeline with diameter over 300mm, and noise reduction for high temperature mediums such as boilers, reaction kettles, shells of tank in power plant, chemical industry, pharmacy etc.Waterproof: Adding moisture repel during producing, we can make waterproof glass wool with excellent water resistance, which overcomes the weakness of general glass wool that insulation effect is reduced after exposed to moisture. It is widely used in curtain walls, air duct, transport equipments, pipes etc.Formaldehyde-free: using environmentally friendly binder such as hot setting resin during producing, we can make formaldehyde-free glass wool felt. It meets the market demand for green, environmentally friendly material, and avoids the hazards of harmful substances for human and environment. It is widely used for thermal and sound acoustic in interlayer of  blower, oven and other equipment.Colorful: according to customer’s special request, we can produce colorful glass wool felt with different colors.

    Our glass wool products have gained ISO9001:2000 and CE certification, and have exported to Russia, Italy, Sweden, Australia, UAE, Pakistan, Philippine etc.
