Silicone foam board can be divided into different types according to different processes

The foamed silicone rubber sheet is made of high-quality thin-layer chromatography silica gel, and is prepared by coating a suitable adhesive on the glass substrate, and has certain requirements on pore volume, specific surface, and pore distribution. According to different molding processes, the foamed silicone rubber sheet is mainly classified into the following two types.

Extruded foamed silicone rubber sheet.

The extruded foamed silicone rubber sheet is extruded by an extrusion molding machine, and the extruded foamed silicone rubber sheet can be rolled and can be cut into different sizes according to installation requirements.

The extrusion molding process has the advantages of high maneuverability, low cost, high output, fast production speed, free cutting length, uniform thickness, and so on. But if you want to cut out the right size, you need to match the mold.

Molded foamed silicone rubber sheet.

Molded foamed silicone rubber sheet requires a silicone mold and a fixed-size silicone sheet that has been vulcanized at a high temperature. The molded foamed silicone rubber sheet has a limited area, fixed-length, and width.

The production process has the characteristics of stable production, good raw material quality, easy control of color, good hardness, high raw material grade, and uniform size.

However, the molded foamed silicone rubber sheet has a bottom yield, and the cost is 2-3 times that of the extruded foamed silicone rubber sheet, and the thickness is not uniform.
