  • Why Choose Our Fire Resistant Insulation Products & Materials

    Why Choose Our Fire Resistant Insulation Products & Materials

    Our fireproof insulation products & materials, including fire sleeves, fire blankets, and fire tapes, are manufactured with high-grade raw materials and advanced production technology. These products are closely combined with practical application scenarios, integrating excellent high-temperature resistance, flame retardancy, durability and easy installation, to provide comprehensive and reliable protection for various industrial fields and effectively solve the safety problems caused by high temperature and fire hazards.

    Our fire sleeves are mainly made of high-performance materials such as fiberglass, silica, and basalt, and are coated with high-temperature resistant silicone rubber to form a multi-layer protective structure consisting of a wear-resistant and flame-retardant layer, a heat-insulating and water-proof layer, and a fire-resistant layer. They can withstand continuous high temperatures of up to 260℃, resist short-term exposure to molten splashes of 1200

    Our fire blankets are made of high-quality fiberglass base material, impregnated with high-temperature resistant silicone rubber on both sides, and do not emit noxious gases when exposed to flame. They can withstand continuous temperatures of 260℃ and short-term high temperatures of up to 1182℃, and have excellent heat insulation performance—when a 1093℃ flame is on one side of the blanket, the ambient temperature on the other side can be reduced to 260℃ or less within 30cm, effectively blocking flame propagation and heat conduction. These fire blankets are widely used in construction sites, industrial workshops, and other places to protect floors, windows, machinery and workers from weld sparks, plasma arc and flame damage, and can also be used as fire protection barriers to buy valuable time for emergency rescue.

    Our fire tapes are made of high-purity silica fiber or heavy-duty knitted fiberglass, backed with high-grade silicone rubber, and have excellent flexibility and adhesion. They are suitable for wrapping hoses, wiring looms and pipelines of any diameter, and can be wrapped spirally without disassembling equipment, which is convenient and efficient. The fire tapes have outstanding high-temperature resistance, flame retardancy and chemical stability, can resist various corrosive media such as oil and acid-base, and are not easy to age under long-term use at 260℃, effectively preventing heat radiation and flame erosion, and enhancing the durability of protected components.

    In addition to the excellent performance of single products, our high-temperature fire protection materials also have the advantages of wide application range and strong customization, covering steel, oil & gas, mining, automotive, aerospace, chemical, railway and other industries. We can provide products of different specifications, thicknesses and finishes according to the specific needs of customers, and have a complete quality control system and after-sales service, ensuring that each product meets international standards and passes strict laboratory tests, such as ISO14001 and ISO9001  certifications.
