1: The difference in form, liquid silica gel is liquid, and solid silica gel is solid. It is easy to distinguish in terms of materials. Liquid silicone can be processed into silicone products, and the processed products are solid. Products processed from solid silicone raw materials are also solid. But we note that liquid silica gel cannot be obtained by heating solid silica gel.

2: Differences in material status. Liquid silicone is generally made of silicone oil, while solid silicone is made of raw rubber.

3: Differences in components: Solid silicone gel generally has only one component, and a vulcanizing agent is added for high-temperature vulcanization; liquid silicone often has two components A/B, one of which contains platinum vulcanizing agent; there are also liquid silicone gels Silica gel puts the catalyst and the main material in the same component, and the vulcanization reaction occurs only at high temperatures or when exposed to moisture in the air.

4: Different molding methods: solid silicone requires high temperature to react with the vulcanizing agent, and processing requires certain equipment; its molding methods include molding, extrusion, and calendering; the molding temperature of liquid silicone is 80℃-120℃ , the production temperature is generally adjusted according to the structure of the product, and liquid silicone molding equipment is generally divided into vertical and horizontal injection machines. Liquid molds require auxiliary aids such as flow channels to transport water, and the precision of the molds is high. This kind of liquid silicone molding requires integrated equipment, and the molding methods include injection and pouring. Cold runners and runner injection

5: The uses of liquid products and solid products are basically the same: after solid silicone is molded, its product uses are more extensive, and its cost and processing technology are relatively mature. However, solid-state products cannot meet production conditions when produced in closed environments under high-demand conditions. At this time, the application of liquid silicone will occur randomly. When the molding process and production equipment of liquid silicone products can meet the requirements of closed production, high-demand medical silicone products, optical silicone products, etc. can be produced. When the silicone products used in your project are met, you can use the liquid silicone process or the solid silicone process according to the project needs.
