Basic Info

Uses

2,4,6,8-Tetramethyl-2,4,6,8-Tetravinylcyclotetrasiloxane is an important intermediate for the synthesis of various organosilicon materials. It can be added to other polymer materials as a modifier to improve the surface properties of the materials. It is used as a crosslinking agent in the vulcanization process of organosilicon rubber. The vinyl functional group can react with hydrogenated silicone oil and other substances to form a crosslinked structure between rubber molecular chains, improve the strength, elasticity and heat resistance of rubber, and enable it to meet the performance requirements of rubber products in different industrial fields.

Safety Information

2,4,6,8-Tetramethyl-2,4,6,8-Tetravinylcyclotetrasiloxane may be flammable. It may cause combustion and explosion when exposed to open flames, high heat or contact with oxidants. Its vapor and air can form explosive mixtures. In a fire, heated containers are at risk of explosion. Inhalation, ingestion or absorption through the skin may be harmful to the body. It is irritating to the eyes, skin and respiratory tract. Contact may cause discomfort symptoms such as redness and pain of the eyes, itching and swelling of the skin. Long-term or large-scale contact may cause damage to the respiratory system, nervous system, etc. During use, appropriate protective equipment should be worn and the operation should be carried out in a well-ventilated environment. It is best to use it in a place with ventilation equipment to prevent vapor accumulation.
