Silicone rubber compound is a new type of environmentally friendly material, non-toxic and odorless, with stable chemical properties, and resistance to high and low temperatures. It is currently widely used in industries such as craft gifts, auto parts, and mechanical equipment. The production and molding of silicone rubber blends requires placing them in a hydraulic press for high-temperature vulcanization molding, especially for some high-yield silicone products, which have extremely strict requirements for the vulcanization time of silicone rubber blends. What is the optimal vulcanization time of silicone rubber blends?

Silicone rubber blends can only be used after adding vulcanizing agents and then refining and thinning out the sheets. Generally, it is better to select "ready to use" as the preferred method. After adding vulcanizing agent, the silicone rubber compound will slowly volatilize over storage time, especially in summer, after adding sulfur, the silicone rubber compound can only be stored for about 15 days, while it can be stored for one month in spring and autumn, and can be effectively stored for 2-3 months in winter. However, sulfurized silicone rubber blends can be stored for a long time due to the gradual volatilization of the vulcanizing agent inside, resulting in difficult vulcanization. The best method is to vulcanize immediately, with the best effect.
Is it best to immediately refine the silicone rubber mixture and put it into use? Actually, it's not. The silicone rubber compound has just been refined, but the surface of the material is still hot. If it is used immediately, there will be white spots and scorched edges. "We should wait until the silica gel mixture has cooled to room temperature before using it. This is the best curing time for the silica gel mixture, with the shortest curing time and the lowest product scrap rate.". If conditions permit, the refined silicone rubber mixture can be stored in an air-conditioned room. It is best to use the materials that have been refined that day.

The best time for vulcanization of silicone rubber blends is when the raw materials are refined and cooled to room temperature before being put into use. Its vulcanization effect will gradually deteriorate over time.
