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. It takes polymethylvinyl siloxane as the main body, and raw materials are combined with various compounds such as silica, siloxane and silicone resin as auxiliary materials. The finished products are produced and molded by high-temperature molding, with 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. After the modulation of raw materials, the solidification state will not appear as the silicone rubber raw materials, and the solidified body can be formed after the fixed telephones. There is no reaction change in the fixed telephones process!
It is different from silica gel products. It cares about processing methods and commercial materials. Silicone gel has higher quality adaptability and environment, and can be applied in any material. Silicone rubber can be automatically healed by force extrusion, and its density is strong enough to prevent moisture and water. Therefore, it is used for waterproofing and moisture-proof of precision electronic components, backlight and electrical modules. Coating, pouring and potting protection against gas pollution.
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.
