How to classify silicone rubber sheets?

The silicone rubber sheet is made of high-purity thin-layer chromatography silica gel, and then transferred into a certain amount of binder, and the surface of the board is also called a thin-layer chromatography silicone rubber sheet, which has high sensitivity and short separation time. It has a good separation effect and clear spots. It is widely used in the identification of pesticides, medicines, foods, herbs and trace impurities and ingredients. There are many classifications of silicone rubber sheets, which can be classified according to specifications, coating thickness, or according to the molding process. Today, we will give you a detailed introduction.

Silicone rubber sheets are classified according to the thickness of the coating, and there are preparation plates and analysis plates; according to the specifications, there are silica gel G, silica gel H, silica gel GF254, silica gel HF254, etc., the models are different, and the amount of gypsum contained therein is different, mainly in the form of silica gel. The viscosity is different, and the higher the gypsum content, the more viscous. Generally, the viscosity of silica gel H is relatively loose, and silica gel G is relatively moderate. According to the molding process, the silicone rubber sheets on the market are mainly divided into two types, a molded silicone rubber sheet and an extruded silicone rubber sheet.

1. Molded silicone rubber sheet
Molded silicone rubber sheet has a fixed length and width and is fixed in size. It is a silica gel sheet formed by high temperature vulcanization and silica gel molding, and its area is limited. The advantages are good quality of raw materials, stable production, uniform size, good control of hardness, color and raw material grade; disadvantages are uneven thickness and high cost, 2-3 times of extruded silica gel plate, and low yield.

2. extrusion silicone rubber sheet
Extrusion Silicone rubber sheets can be cut to length or rounded together. The extruded silicone sheet is made of an extrusion molding machine like a ribbon. The advantages are high output, uniform thickness, high maneuverability and production speed, and low cost; the disadvantage is that the die needs to be matched later to cut a specific shape.

How to classify silicone rubber sheets? Through the above description, everyone has a certain understanding, the raw material of silicone rubber sheet is mainly high-quality thin-layer chromatography silica gel, which has the specified specific surface, pore volume and pore distribution, which has been widely used, and everyone can Choose your own silicone rubber sheet for your own needs.
