Silicone rubber is classified into three major types based on its vulcanization mechanism: heat-vulcanized, room-temperature-vulcanized, and addition-reaction-type, each with unique characteristics and applications.

Heat-Vulcanized Silicone Rubber: Utilizes organic peroxides as vulcanizing agents, which decompose under heat to create cross-links, forming vulcanized rubber. These rubbers exhibit a wide temperature range of adaptability (-60°C to 250°C) and encompass various types such as dimethyl silicone rubber, methyl vinyl silicone rubber, and phenyl silicone rubber, widely used in electrical, mechanical, automotive, and other industries.

Room-Temperature-Vulcanized Silicone Rubber: Vulcanizes at room temperature without heating, offering convenience in use. Commonly used for mold making, coatings, and sealing materials, particularly suitable for applications requiring rapid curing.

Addition-Reaction-Type Silicone Rubber: Vulcanizes through addition reactions, boasting exceptional heat and cold resistance, maintaining stable performance under extreme conditions. Widely employed in high-tech fields such as aerospace and nuclear energy.

With its diverse classifications and superior performance, silicone rubber has become an indispensable polymer material in modern industries.
