Foamed silica gel is an important material in the industry. Its products have good water resistance, ozone resistance, weathering resistance, corrosion resistance and a wide range of applications, but many newcomers do not know some of his descriptions and reference indicators. Take everyone to see his descriptions and indicators today.


     Foamed silica gel is also called addition molding silica gel, and two-component addition molding silica gel. It consists of two parts: the A component is silica gel and the B component is a curing agent; the two components are mixed in a ratio of 1:1. This product is a soft elastic material after white vulcanization.


The foamed silica gel product is a pure organic silicon material which is chemically foamed, and has a small pore size and a fine uniformity after foaming. Foamed silica gel is an environmentally friendly material, and the products produced are non-toxic and tasteless, safe and hygienic.
