Silica gel is divided into liquid silica gel and solid silica gel, which are two different production processes, and different material production.So which is soft, silicone or liquid silicone?

    First of all, we need to have an idea of the softness, which refers to the softness of the silicone when we touch it with our hands.The international unit we usually use to measure this softness is Shore A hardness.Whether it is liquid silica gel or liquid silica gel, the hardness of silica gel itself can be adjusted according to different hardness requirements, so there is no hard which soft.But solid silica gel usually does not make products below 20 degrees of hardness, because of the defects of its own process;Solid silica gel belongs to high temperature vulcanization molding, high temperature vulcanization molding needs the help of machinery and steel film to operate, the produced silica gel products have flying edge, the softer the hardness of silica gel, then the more troublesome the treatment of flying edge, generally speaking, the basic will not silica gel factory will be connected with the hardness of 20 Shaw A below the product.Liquid silica gel does not have this limitation. 

    Liquid silica gel can be cured at room temperature or heated. It is not limited by the machine and can be manually operated, so the requirements for hardness are not so high.

    So through the above should be able to understand, if only a simple product to compare the hardness of no high and low points, solid silica gel can also make a very soft hardness, by adding materials can;If from the current majority of silicone products, most of the choice is liquid silicone.
