Silicone rubber can be divided into liquid silicone rubber and solid silicone rubber according to the existing types. The physical properties of the two are different due to the different shapes, and the application is also quite different.
                              
      Let's talk about solid silicone rubber first. The vulcanized silicone rubber products and silicone rubber are solid. The solid silicone rubber we are talking about here refers to silicone rubber. This kind of silicone rubber is also called high temperature silicone rubber. No matter which kind of vulcanizing agent is used, it needs to be vulcanized at high temperature to complete the vulcanization and obtain the ideal physical properties.

      After the solid silicone rubber is vulcanized, it can be made into various silicone products, which generally have good physical properties. The solid silicone rubber products can generally pass the FDA test after secondary vulcanization to achieve food-grade standards. Therefore, solid silicone rubber can be used not only for industrial products, but also for food contact.

      There are many varieties of liquid silicone rubber, but it is more liquid than the original uncured silicone material. Due to its vulcanizability, liquid silicone rubber is easier to mold, and can be easily made into molds to replicate products. This is not possible with solid silicone rubber. Liquid silicone rubber can also be used as an adhesive to bond various materials. Most liquid silicone rubbers can be vulcanized at room temperature.

      Liquid silicone rubber can be divided into condensation type liquid silicone rubber and addition type liquid silicone rubber according to reaction type. Condensed silicone rubber generally does not meet food-grade standards, while addition-molded silicone rubber generally meets food-grade standards and has very good physical properties. Therefore, it is made into liquid silicone products and used in various industries.
