As a high-performance liquid elastomer, liquid fluorosilicone rubber has excellent processing performance and can be automatically produced through various methods such as injection, extrusion, and molding, greatly shortening the production cycle and reducing the scrap rate.

Its solidification mainly relies on two different chemical mechanisms, namely condensation type and addition type. The sulfurizing group of condensed liquid fluorosilicone rubber is hydroxyl, which can usually be made into single component or two-component products. Single component products can be cured by absorbing moisture from the air, making them very convenient to use.

However, this type of material releases small molecule by-products during the curing process, resulting in a relatively large volume shrinkage rate, which to some extent limits its application in high-temperature sealed fields. In contrast, the sulfurizing group of the addition formed liquid fluorosilicone rubber is vinyl, and its curing process is achieved through the addition reaction between silicone vinyl and silicon hydrogen bonds.

The biggest advantage of this reaction mechanism is that it does not produce any by-products, resulting in minimal material shrinkage and the ability to achieve deep and uniform vulcanization. With these technological advantages, additive liquid fluorosilicone rubber has become a higher grade and more widely used variety in the current market, especially suitable for manufacturing industrial components with complex structures and extremely high dimensional precision requirements.
