Making silicone rubber sheet is a delicate process involving multiple steps, from the preparation of raw materials to the molding of the final product. First, the production of silicone rubber sheet requires the selection of high-quality silicone raw materials, which usually include silicone resin, cross-linking agent and filler. These ingredients are precisely proportioned to ensure that the silicone rubber sheet has the desired performance characteristics, such as high temperature resistance, elasticity and corrosion resistance.
During the mixing process, the silicone raw materials are mixed at high temperature in an internal mixer to ensure that the cross-linking agent and filler are evenly distributed. Next, the mixed silicone material is sent to a calender or extruder for molding. At this point, the thickness and width of the silicone rubber sheet will be adjusted according to customer needs. The molded silicone rubber sheet needs to undergo a high-temperature vulcanization process to ensure that the silicone molecules form a cross-linked structure, thereby giving it good mechanical strength and stability.
After vulcanization, the silicone rubber sheet will be cooled to room temperature and cut and trimmed to meet the final size and appearance requirements. At this time, the silicone rubber sheet has excellent properties, including excellent elasticity, wear resistance and good chemical stability.
In general, the manufacture of silicone rubber sheet is a process with high technical requirements and complex processes, and strict control of raw material ratios and production conditions is required to ensure the quality and performance of the final product.
