Room temperature vulcanized silicone rubber can be vulcanized and formed under conventional temperature environment, while high temperature vulcanized silicone rubber needs to be vulcanized and formed under high temperature environment. This is the most obvious difference between the two. This is also the origin of their names.

Vulcanizing agents used in RTV silicone rubber and HTV silicone rubber are also different. The former uses basic rubber, crosslinking agent, filler, filler and other materials for normal temperature vulcanization, while the latter uses double 25 vulcanizing agent for high temperature molding or extrusion.

Room temperature vulcanized silicone rubber is produced from 107 methyl vinyl silicone rubber, while high temperature vulcanized silicone rubber is produced from 110 methyl vinyl silicone rubber. The surface of room temperature vulcanized silicone rubber is liquid, while the surface of high temperature vulcanized silicone rubber is solid.

Therefore, room temperature vulcanized silicone rubber is also referred to as liquid silicone, while high temperature vulcanized silicone rubber is referred to as solid silicone (mixed silicone rubber). Liquid silicone is mainly used in human silicone, printing silicone, medical silicone, mold silicone, automobile and ship silicone, military supplies silicone and aerospace silicone; Solid silica gel is mainly used in silica gel craft gifts, mechanical parts, auto parts, sanitary ware, adult products and other industries.

Briefly summarize the difference between room temperature vulcanized silicone rubber and high temperature vulcanized silicone rubber. The appearance of room temperature vulcanized silicone rubber is liquid and can be vulcanized and formed under conventional environment, while the appearance of high temperature vulcanized silicone rubber is solid and needs to be formed under high temperature vulcanization. Because they belong to the silicone rubber series, they also have some common ground. They can withstand high and low temperature, and have excellent electrical insulation performance, ozone resistance, weather aging resistance, hydrophobicity, moisture resistance, and good physiological inertia. Both of them are widely used in life and industry.
