Made from extremely fine E-type glass fibers and needle-punched by a special needle-rolling machine, the fiber mat forms countless tiny cavities. It is a non-toxic and harmless inorganic material. Compared to traditional centrifugal glass wool and asbestos products, it excels in heat resistance, tensile strength, toughness, fire resistance, and corrosion resistance. Its heat resistance can reach up to 700℃, and it has excellent electrical insulation properties. Its unique flexibility facilitates cutting and trimming, making it a distinctive new eco-friendly product among various existing insulation and sound-absorbing materials.
