Flame-retardant sealing strips are flame-retardant rubber products and are used in building fireproof and waterproof sealing materials, fireproof door and window sealing, pipe sealing, curtain wall seams, mechanical equipment sealing, cabinet sealing, automobile door and window strips, etc. The requirement for flame-retardant sealing strips is fire resistance. The requirement for fire resistance is that after a fire occurs, our flame-retardant sealing strips must maintain a certain strength after burning, which can block early smoke and reduce toxic gases Heat is harmful to the human body, and the flame-retardant sealing strip can prevent the fire from spreading.
The flame-retardant sealing strip has been developed through many rubber product mix tests and actual process assessments by rubber product manufacturers and has developed a rubber sealing strip with high flame-retardant performance. The microwave continuous vulcanization method is used to make this flame-retardant sealing strip product have It has good resilience, flexibility, and chemical stability, is not easy to burn when exposed to open flames, no bubbles and pores on the surface, high strength, long use time, not afraid of compression, and good appearance quality.
The flame-retardant sealing strip product is environmentally friendly and easy to construct. It is not only flame-retardant, but also anti-seepage, leak-proof, aging-resistant, acid-resistant, alkali-resistant, and water-stopping. The use environment of the flame-retardant sealing strip can also be determined according to the market. Customized production according to the needs of the situation, flame-retardant sealing strips are now divided into three flame-retardant grades (levels a, b, and c). Class A flame-retardant sealing strips are flame-retardant, with an oxygen index of 32%, meeting the b1 standard of the national building design code; Class B flame-retardant sealing strips are flame-retardant, with an oxygen index of 26%, meeting the b2 standard of the national standard design code; C Grade 1 flame retardant sealing strip is a commonly used sealing material, and its temperature resistance is not less than 120°C.
Before ordering flame-retardant sealing strips, please confirm the necessary dimensions/parameters with the salesperson of the rubber sealing strip manufacturer to avoid purchasing the wrong product and being unable to use it; Guangdong Zhongxiang New Materials Co., Ltd. supports customized flame-retardant seals based on drawings and samples.
