This product uses inorganic E-type glass fiber, which is mainly composed of silica and alumina. All products have undergone strict comprehensive inspection and systematic quality control to ensure consistent product performance and provide customers with safe and continuous production assurance. This product is made of extremely fine E-type glass fibers and then needle punched by a special needle rolling machine, resulting in countless small holes in the fiber felt, giving it extremely high heat insulation and sound absorption characteristics. It is a non-toxic and harmless inorganic material. Compared with the traditional centrifugal Glass wool and asbestos products, it does not contain any adhesive, will not give off any flavor, and does not contain any Carcinogen. It has excellent heat resistance, tensile strength, toughness, fire resistance, corrosion resistance, etc., especially the heat resistance is four times higher than the centrifugal Glass wool, up to 750 degrees. The electrical insulation is particularly good. The unique flexibility facilitates cutting and cutting, making it a more distinctive new environmentally friendly product among various existing insulation and sound-absorbing materials.

Main uses: 1. The characteristics of using fiberglass needle felt in the inner core of a muffler are: high porosity, high sound absorption rate, and low thermal conductivity. In addition, glass fiber itself has characteristics such as high heat resistance, good strength and toughness, and corrosion resistance, making it widely used in the field of automotive and motorcycle silencers in major automobile production countries. Firstly, utilizing its excellent sound absorption performance to achieve noise reduction effects; Secondly, utilizing its high insulation and heat resistance performance, the mixed gas undergoes sufficient chemical reactions in the high-temperature environment of the exhaust pipeline, thereby achieving low emissions of exhaust gas. 2. The surface of the glass fiber needle felt is bonded with aluminum foil, plastic cloth, glass fiber cloth, etc. After processing and cutting into strips, it is used for insulation and protection of cold and hot pipelines as well as underground pipelines; The insulation and sound insulation of the generator set can also be used for the insulation and sound insulation of colored steel tiles, with excellent results. 3. After immersing the fiberglass needle felt into resin and processing it into a plate shape, it can be used as insulation and sound insulation material for building and air conditioning machine liners.
