What is the difference between silicone gel and silicone rubber?

A lot of friends know that silicone rubber products have a certain strength category. Although it looks soft, it can not reach the standard beyond certain hardness and softness. For example, too hard or too soft goods will be replaced by natural rubber and other synthetic rubber. Hardness is too soft and may be replaced by different materials, such as silicone gel is one of them. As a hot material in recent years, how is it different from silicone rubber?

Silicone rubber products belong to solid-state molding processing, which is mainly composed of polymethylvinyl siloxane. The raw materials are combined with various compounds such as silica, siloxane and silicone resin as auxiliary materials. The finished products have good softness, hardness and softness between 20-80 degrees.

Silicone gel is also one of the silica gel, and it is mainly liquid molding to achieve -40 degree of softness, high purity and strong elasticity. It is semi solidified after forming and solidifying. It is used as a basic sealing material for many kinds of auxiliary seals. It has good sealing performance and high temperature resistance. Fixed state, and fixed after the formation of solidified body, fixed in the process of no reaction changes!

It is different from silicone products. It cares about processing methods and commercial materials. Silicone gel has higher quality of adaptability and environment, and is applied in any substance. Silicone rubber can be automatically healed by force extrusion, and it can be moisture-proof and waterproof. Therefore, it is used for waterproof, moisture-proof and gas pollution of precision electronic components, backlight and electrical modules. Coating, pouring and potting protection, etc.

Silicone gel can be divided into many types of use, and our common medical materials and other materials will use medical grade silicone gel material. Because it has zero degree of softness and has automatic healing conditions, it can contact the skin and human body for a long time.
