Many friends know that silicone rubber products have a certain range of strength. Although it looks soft, the compounded rubber that exceeds a certain hardness and softness standard does not meet the standard. For example, the product is too hard or too soft. It is replaced by natural rubber and other synthetic rubber. If the hardness is too soft, it may be replaced by different materials. For example, 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 is mainly composed of polymethyl vinyl siloxane. The raw materials are combined by a variety of compounds such as white carbon black, silicone, and silicone resin. The finished product is produced by high-temperature molding and has good softness and hardness between 20-80 degrees.
Silicone gel also belongs to one of the silicone gels, and it mainly has liquid molding that can reach -40 degrees of flexibility, and has high purity and strong elasticity. It is in a semi-solid state after molding and curing. It is used as A variety of auxiliary sealing basic materials have good sealing properties, and have a certain high temperature resistance. The raw materials are prepared and the silicone rubber materials will not solidify, but they can form a solidified body after fixing. Variety!
It is not the same as silicone products. It cares about processing methods and commercial materials. Silicon gels have higher quality adaptability and environmental properties and can be used in any substance. In addition, silicone gels can automatically heal after being squeezed and damaged. Water-proof, so it is used for coating, pouring and potting protection of precision electronic components, backlights and electrical modules.
Silicone gel can be divided into various types of use, and our common medical materials and other materials will use medical grade silicone gel material, because it has sub-zero softness and automatic healing conditions, it can contact the skin for a long time As well as the human body.
