Foamed silicone, as a material with outstanding performance, has been widely used in numerous fields. It is made by thoroughly mixing silicone raw materials and curing agents in a ratio of 1:1. Through chemical foaming and vulcanization of pure silicone materials, a soft material is finally formed. It features fine and uniform pore sizes and belongs to environmentally friendly polymer materials. The silicone products produced are not only non-toxic, odorless, safe and hygienic, but also soft, lightweight, and have a good hand feel. Moreover, there are no restrictions on the thickness of the products during the manufacturing process, and the operation is simple and convenient.

Foamed silicone can be divided into two types according to its form, namely solid and liquid. Among them, liquid foamed silicone has unique characteristics. It has a relatively low viscosity and can flow freely under normal temperature or heating conditions. This characteristic gives it great advantages in processes that require high precision in molding or fine filling. For example, it is widely used in fields such as electronics and medical treatment. When preparing liquid foamed silicone, it is necessary to accurately adjust the proportions of various components in the formula and add specific additives to achieve the desired liquid form and excellent fluidity.
The application range of foamed silicone is extremely wide. It can be seen in soft silicone products such as anti-slip mats, silicone breast pads, silicone foam boards, and silicone shoulder pads. It also has high practical value in silicone foam insulation pipes, impact-resistant silicone foam boards, silicone foam sealing strips, silicone foam rolls, printer shaft sponge tubes, and copier transfer roller shaft sponge tubes. Whether it is for shock-absorbing and cushioning accessories or the filling of rubber-coated products, foamed silicone can play a significant role.
When using liquid silicone, special attention should be paid. It should not be in contact with other condensation-type silicone raw materials, otherwise it will cause problems such as non-curing and foaming of the silicone. Meanwhile, organotin catalysts containing sulfur, phosphorus, and nitrogen elements, as well as impurities such as acids and alkalis, will also have an adverse impact on the curing of silicone. During the use process, it is necessary to avoid the mixing or contact of these substances.
