Classification of liquid silicone rubber types

Liquid silicone rubber can be divided into two categories, condensation type silicone rubber and addition type silicone rubber. Condensed silicone rubber belongs to industrial grade silicone rubber, and addition molded silicone rubber belongs to food grade silicone rubber. These two major categories can be divided into different sub categories. How are the two types of liquid silicone rubber divided?

Condensed silicone rubber can be subdivided into many small categories. We have specialized in developing different types of silicone rubber for different industries to provide better and more suitable liquid silicone rubber. The common condensation type silicone in the market mainly includes RTV-2 mold silicone rubber, RTV-2 hand board model design silicone rubber, RTV-2 pad printing silicone rubber, RTV-2 shoe mold silicone rubber, RTV-2 electronic potting adhesive, etc. Among them, mold silicone rubber, hand mold silicone rubber, and shoe mold silicone rubber are mainly used for mold design and model manufacturing, while pad printing silicone rubber is mainly used for making pad printing adhesive heads, while potting adhesive is mainly applicable to the insulation, moisture-proof, waterproof, and fixation of electronic accessories, and is widely used for potting general electrical modules and as a protective material for external potting of LED displays.

Addition molding silicone, a common addition molding liquid silicone in the market, mainly includes human silicone rubber, clothing label silicone rubber, injection molding silicone rubber, and other human silicone rubber products. It can mainly be used to produce flexible silicone rubber products such as sexual products, human organs, human body shape, chest pads, shoulder pads, patches, anti-slip pads, and other flexible silicone rubber products. Clothing label silicone rubber, with this product can be made into a separate trademark, and can also be made into a trademark using methods such as cloth pressing and leather pressing. Generally used for the production of trademarks for various products such as jeans, shoes, toys, etc.

Condensation type silicone and addition type silicone are both two component liquid silicone. The main ratio of condensation type silicone A adhesive and B curing agent is 100:2-5, and some special products are 10:1. The main proportion of addition molded silicone A and B adhesives is 1:1, and the proportion of some special products is 10:1 and 9:1.

From the above classification, both types of silicone rubber have the same goal in different ways, but the application of the two types of silicone rubber is different. When choosing, don't make a mistake. If you don't know how to choose, if necessary, you can consult us for professional advice and suggestions.
