Ceramic fire-resistant silicone rubber is a special silicone rubber refractory made of silicon rubber as a base material, adding ceramic-forming additives and functional fillers, after a certain processing process. Ceramic fire-resistant silicone rubber has the general properties of ordinary silicone rubber materials under normal conditions. It can be quickly sintered into a hard "caramelized" case at a temperature of 600 ° C and above, thereby giving the material excellent fire resistance and heat insulation, Thermal shock resistance and other characteristics.
Compared with inorganic refractory materials, ceramic fire-resistant silicone rubber has the advantages of simple and diverse mounding processes, waterproof and moisture-proof, non-toxic and harmless, environmental protection, and other advantages. It is not inferior in terms of fire resistance and has better thermal insulation effect.
Characteristic: Leading professional and technical level Has dozens of independent intellectual property rights, has international advanced formula design capabilities and domestic leading production technology level
Excellent mechanical and electrical properties Low density, no water absorption, no moisture absorption, good flexibility and elasticity under normal conditions, excellent mechanical and electrical properties, good high and low-temperature resistance, normal use temperature -60 ° C ~ + 200 ° C.
Excellent environmental performance Low-smoke, halogen-free, phosphorus-nitrogen-free, non-heavy metal, and smoke toxicity safety level reaches the highest safety level ZA of polymer materials, which will not cause secondary harm to the human body, and its environmental protection performance complies with the EU RoHS directive.
Excellent refractory performance Under the high temperature or flame of 600 ° C to 3000 ° C, it can be quickly burned into a complete and hard ceramic-like shell. The ceramic shell does not melt, shrink, or drip at high temperatures, and has excellent fire insulation Thermal effect.
Good processability Ceramicized silicone rubber has the same processing technology as ordinary silicone rubber, and is suitable for extrusion, moldings, calendaring and other processes, without the need to change the process and additional equipment.
High fire-resistance rating Fire-resistant and fire-resistant cable produced by ceramicized fire-resistant and fire-resistant silicone rubber have excellent fire resistance and the fire resistance level can meet the following standards: (1) CWZ maximum fire-resistance rating of BS 6387 and BS 8491 (2) IEC 60331 standard (3) GB / T 19216 standard (4) GA 306.2 fire resistance class A standard
Applications: Ceramic fire-resistant silicone rubber is widely used in fire-resistant wire and cable, fire auxiliary materials, power battery safety protection, aerospace, and other fields due to its excellent fire resistance characteristics. The application range of medium and low voltage refractory wires and cables produced using this material is very wide, such as hospitals, theatres, commercial buildings, subways, tunnels, railways, airports, stations, large public sports, entertainment venues, large supermarkets, hotels and other densely populated places; TV stations, nuclear power plants and other areas with strict requirements for power and communication facilities; coal, chemicals, medicine, steel, metallurgy, ships and other areas with harsh external environments.
