Many times, when we say "silicone rubber", we use the singular to refer to the same thing, but it is more correct to use the plural to refer to silicone resin and silicone rubber, because the term "silicone rubber" means silicon-based material-oxygen The chain changes depend on the type of processing and the catalyst used to stabilize them.

Through different temperatures and different polymerization methods, we can obtain various types of silicone rubber with different characteristics. Therefore, we can find different types of products on the market, the hardness of which varies between 10-90 sh.A. Based on compound formula. Due to its excellent mechanical, non-stick and elastic properties, silicone rubber is used in many different industrial and process applications, such as https://www.diecasting-mould.com/rubber-coating rubber coating and hoses, automotive parts, sealing and electrical protection. Now let us look at the different types of silicone rubber.

Types of silicone rubber
Solid Silicone Rubber (VMQ)-This type of silicone is sold on the market in solid form and must be cured through a high-temperature vulcanization process. It shows excellent performance and is widely used in various industries.

Liquid Silicone Rubber (LRS)-Unlike the previous one, this silicone rubber is liquid on the market; it is a high-temperature vulcanized rubber with low viscosity and short cycle time. It is a two-part compound that must be mixed with a catalyst for polymerization.

Room temperature vulcanization-is a two-component rubber that crosslinks at room temperature or with the help of heating. The two-component silicone rubber is silicone rubber, which can be ideal for creating liquid or soft molds.

Characteristics of silicone rubber
Despite the differences, silicone rubber has many of the same characteristics.

Not sticky. Silicone rubber molds, profiles and gaskets prevent other materials from sticking to them. This is why silicone molds are so popular in the kitchen, industry, and art. After pouring the selected material into the mold, just wait for it to solidify before taking it out. No release processing of any kind is required.

Elasticity and resistance. Silicone can stretch a lot without tearing, so it is suitable for strong mechanical stress.

The high fidelity of the model. Once the silicone is poured into the mold, you can be sure that the casting will be exactly the same as the original model. Therefore, it is easy to obtain a large number of flat rubber washers or O-rings, which are exactly the same as the mold and identical to each other.

Tolerate various temperatures. Silicone rubber can maintain its characteristics at temperatures of -150°C and +200°C and higher. Therefore, they can be used in critical climatic conditions or exposed to high or low temperatures.

The high fidelity of the color. Due to its ductility, silicone rubber maintains high fidelity to colors while maintaining brightness and covering the entire RAL range.
