① Dosage of curing agent. The larger the amount, the faster the vulcanization speed, and the higher the degree of vulcanization that can be achieved. The solubility of vulcanizing agents in silicone rubber is limited. Excessive vulcanizing agents will be precipitated from the rubber surface, commonly known as "sulfur spray". In order to reduce the sulfur injection phenomenon and achieve the vulcanization effect, it is necessary to strictly control the amount of vulcanizing agent.

② curing temperature. If the temperature is 10 ° C higher, the curing time is shortened by about half. Because rubber is a poor thermal conductor, the vulcanization process of the product is different due to the temperature difference of its various parts. In order to ensure a relatively uniform vulcanization degree, thick rubber products are generally vulcanized by gradually increasing temperature and low temperature for a long time.

③ curing time. This is an important part of the vulcanization process. The time is too short, and the degree of vulcanization is insufficient (also called undersulfur). Too long time, too high degree of vulcanization (commonly known as over sulfur). Only the appropriate degree of vulcanization (commonly known as normal vulcanization) can ensure the best comprehensive performance.
