High-temperature vulcanized silicone rubber (HTV) has a wide range of applications and China’s production capacity is expanding rapidly

There are many types of silicone rubber. According to different vulcanization mechanisms, it can be divided into two categories: high-temperature vulcanized silicone rubber and room temperature vulcanized silicone rubber. High temperature vulcanized silicone rubber (HTV) refers to an elastomer made from high molar mass linear polydimethylsiloxane as the base polymer, mixed with reinforcing fillers and vulcanizing agents, and vulcanized. High-temperature vulcanized silicone rubber has the advantages of good weather resistance, high/low temperature resistance, and high precision. It is widely used in many fields such as medical and health care, national defense industry, petrochemical industry, building materials, and household appliances.

According to different chemical compositions, high-temperature vulcanized silicone rubber can be divided into methyl vinyl silicone rubber (VMQ), dimethyl silicone rubber (MQ), methyl vinyl phenyl silicone rubber (PVMQ), nitrile silicone rubber (NVMQ), Fluorosilicone rubber (FVMQ), etc. Methyl vinyl silicone rubber is a representative product of high-temperature vulcanized silicone rubber and can be used to manufacture various seals. With the growth of market demand for segmented products, the prosperity of the high-temperature vulcanized silicone rubber industry will further increase.
