The manufacturing process of HTV silicone rubber involves compounding high-molecular-weight polysiloxanes with reinforcing agents such as silica (SiO2) and various additives like vulcanizing agents, structural control agents, and modifiers. The compounded rubber is then heated and vulcanized in a mold under a certain pressure and high temperature, followed by demolding and secondary vulcanization in an oven.

One of the notable characteristics of HTV silicone rubber is its highly stable siloxane bond structure, which provides it with heat resistance, electrical insulation, and chemical stability. Additionally, its helical structure gives it good elasticity, stretchability, and cold resistance. HTV silicone rubber also exhibits unique surface properties such as water repellency and mold release, making it excellent for various applications.

Depending on the side groups, HTV silicone rubber can be classified into different types such as methyl silicone rubber, dimethylvinyl silicone rubber, and methylvinylphenyl silicone rubber. These different types of HTV silicone rubber have varying properties and applications, such as low-temperature resistance, radiation resistance, and flame retardancy.
