Introduction of ultra-low temperature resistance:
Low temperature resistant silicone rubber refers to the silicone rubber with a working temperature of -100 ° C. Its structure is different from that of room temperature silicone rubber. It is the introduction of methyl phenyl siloxane or diphenyl silicon into the molecular chain of methyl vinyl silicone rubber. derived from the oxygen chain. The introduction of a phenyl group on the side group of polysiloxane can greatly reduce the crystallization temperature of the polymer due to the destruction of the regularity of the dimethylsiloxane structure, and the working temperature of the resulting silica gel is extended to -100°C.

Features of ultra-low temperature resistant silicone rubber:
Small compression set, wide operating temperature range, oxidation resistance, weather resistance, shock resistance, moisture resistance and good electrical insulation properties, low temperature resistance, ablation resistance and radiation resistance.


Low temperature resistant silicone rubber application fields:
It is one of the important materials in the aerospace industry, cutting-edge technology and other sectors of the national economy. It can be used to make various molded and extruded products, used as cold-resistant rubber in the aviation industry and used in ablation-resistant, heat-resistant aging or radiation-resistant parts.
