Classification of Liquid Silicone Rubber

Ⅰ. Classification of liquid silicone rubber

Liquid silicone rubber can be divided into one-component liquid silicone and two-component liquid silicone according to its packaging form. According to the cross-linking mechanism, it can be divided into two types: condensation type liquid silica gel and addition type liquid silica gel.

Condensed liquid silicone rubber is a small number of addition-molded liquid silicone rubber that can be vulcanized into an elastomer at room temperature, so it is also called room temperature vulcanized silicone rubber (referred to as RTV rubber).

According to the packaging form and cross-linking mechanism, liquid silica gel can be divided into one-component liquid silica gel and two-component liquid silica gel.

One-component liquid silica gel:

1. Condensed liquid silica gel-RTV:

(1) Deacetic acid type RTV

(2) Dealcoholized RTV

(3) Deketoxime type RTV

(4) Deamidated RTV

(5) Deaminated RTV

(6) Acetone-free RTV

2. Addition of liquid silicone-LTV

Two-component liquid silica gel:

1. Condensed liquid silica gel-RTV:

(1) Dealcoholized RTV

(2) Dehydrogenated RTV

(3) Deaminated RTV

(4) Dehydroxyamine RTV.

2. Addition of liquid silicone (RTV, LTV)

Ⅱ. The use of liquid silicone rubber

Liquid silicone rubber can be used for trademarks, products, pacifiers, medical supplies, coating, impregnation and perfusion, etc. For the medical treatment, there is medical grade liquid silicone, which is very safe.

It can also be used in molding molds, injection molding processes, cake molds and other silicone products for crystal glue, polyurethane, epoxy resin, etc. In the electronics industry, it is widely used as a coating and potting material for moisture-proof, consignment and insulation of electronic components, and protects electronic components and assemblies from dust, moisture, shock and insulation.
