Liquid silicone rubber, also known as two-component addition silicone rubber, is distinguished from mixed semi-solid silicone rubber and common room temperature vulcanizing single-component silicone rubber. It is characterized by good fluidity, fast vulcanization, higher safety, and environmental friendliness, meeting food-grade requirements. Liquid silicone rubber can be classified into remote-claw liquid rubber and non-remote-claw liquid rubber based on the position of functional groups in its molecular structure. Furthermore, it can be divided into single-component liquid silicone rubber and two-component liquid silicone rubber based on packaging form, and condensation-type liquid silicone rubber and addition-type liquid silicone rubber based on crosslinking mechanism.
In recent years, with technological advancements and increasing market demand, the research and production technology of liquid silicone rubber materials have continued to innovate. For example, Chinese enterprises have obtained multiple related patents for the preparation methods of addition-type liquid silicone rubber, including heat-resistant transparent addition-type liquid silicone rubber, halogen-free flame-retardant reinforced addition-type liquid silicone rubber, and ultra-low hardness two-component addition-type liquid silicone rubber. These innovations have not only improved the performance of liquid silicone rubber but also broadened its application fields.
Liquid silicone rubber is widely used in medical supplies, infant products, electronic products, trademarks, coatings, impregnations, and infusions. For instance, in the electronics industry, liquid silicone rubber is extensively used as coating and encapsulating materials for moisture protection, transportation, and insulation of electronic components, providing dustproof, moisture-proof, shockproof, and insulating protection for electronic components and assemblies. Additionally, liquid silicone rubber can be used to manufacture molding molds for materials such as gypsum, wax, and epoxy resin, applied in high-frequency embossing of artificial leather, shoe surface modeling, arts and crafts manufacturing, and various other industries.
