Shenzhen Petersburg Composite Materials Co., Ltd

This industrial-grade fiberglass sealing tube is made of high-purity glass fiber yarn. It has excellent high temperature resistance, heat insulation, fire resistance, corrosion resistance and other multiple properties. It is an ideal upgrade alternative to traditional asbestos sealing materials. It is widely used in thermal sealing and insulation of boilers, furnaces, flues, pumps, valves, heat exchangers and other equipment, effectively improving the thermal efficiency and safety protection level of industrial systems. Core advantages 1. High temperature resistant design with stable temperature resistance, suitable for extreme environments up to 550°C~1000°C. The thermal insulation effect is significant, reducing heat loss and improving energy efficiency 2. Class A fireproof material, safe and reliable non-combustible fiberglass material, meets Class A fireproof standards and maintains structural stability in high temperature and open flame environments 3. High corrosion resistance and environmental adaptability to resist erosion by acids, alkalis, oils, and chemical corrosive media. It is resistant to ultraviolet rays and ozone, suitable for outdoor or highly corrosive working conditions 4. Excellent sealing and thermal insulation performance Multi-strand glass fiber braided knot Structure, strong sealing can be used for gap filling, thermal insulation and fire partition 5. Strong durability, reusable High fatigue resistance, not easy to deform or shrink after long-term use Low maintenance cost, support long-term industrial continuous use Typical application scenarios Boiler and furnace body gap sealing: ensure the thermal efficiency of the furnace body and prevent heat leakage Chimney and flue insulation protection: enhance the thermal stability and safety of the exhaust system Valve/pump body/heat exchanger heat shield: improve the thermal management performance of core components Equipment joint and flange sealing: reduce heat loss and prevent high-temperature pressure relief Industrial fire curtain & heat shield production raw materials are environmentally friendly and safe · Asbestos-free formula This product is 100% asbestos-free, non-toxic and harmless, in line with EU ROHS, REACH and other environmental certification requirements, suitable for engineering projects with strict requirements on personnel safety and environmental protection regulations.
