Silica gel

Organic silica gel is a kind of organic silicon compounds, refers to contain Si - C keys, and at least one organic group is directly linked to the silicon atoms compounds, habits are often those with oxygen, sulfur, nitrogen, etc organic base connected to the silicon atoms compounds as organic silicon compounds. Among them, polysiloxane, which is composed of silicon oxygen bond (-si-o-si -), is the largest and most widely used one in organic silicon compounds, accounting for more than 90% of the total amount.

Extruded silica gel is more common, such as the household electric rice cooker on the sealing ring, called the electric rice cooker silicone seal ring.

The moulded silica gel is a bit more complicated, with irregular shape, including silica gel bowl, silica gel ice cube, silica gel cake mold, etc.
