Firstly, literally speaking, room temperature vulcanized silicone rubber can be vulcanized and formed under normal temperature conditions, while high-temperature vulcanized silicone rubber needs to be vulcanized and formed under high temperature conditions. This is the most obvious difference between the two, and it is also the origin of the differences in names between the two.

Secondly, room temperature vulcanized silicone rubber and high-temperature vulcanized silicone rubber also use different vulcanizing agents. The former uses base rubber, crosslinking agents, fillers, and other materials for room temperature vulcanization molding, while the latter uses double 25 vulcanizing agents for high-temperature molding or extrusion molding.

In addition, room temperature vulcanized silicone rubber is produced using 107 methyl vinyl silicone rubber, while high-temperature vulcanized silicone rubber is produced using 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 also referred to as solid silicone (mixed silicone rubber). Liquid silicone is mainly used in human silicone, printed silicone, medical silicone, mold silicone, automotive and marine silicone, military silicone, and aerospace specific silicone; Solid silicone is mainly used in industries such as silicone craft gifts, mechanical parts, automotive parts, bathroom fixtures, and adult products.

Finally, let me briefly summarize the differences between room temperature vulcanized silicone rubber and high-temperature vulcanized silicone rubber. Room temperature vulcanized silicone rubber has a liquid appearance and can be vulcanized and formed in conventional environments, while high-temperature vulcanized silicone rubber has a solid appearance and needs to be formed under high-temperature vulcanization. Because both belong to the silicone rubber series, they also have certain similarities, such as resistance to high and low temperatures, excellent electrical insulation performance, ozone resistance, weather aging resistance, hydrophobicity, moisture resistance, and good physiological inertness. Both have extensive applications in daily life and industry.
