To dissolve MS, STP-E and 107 silicone rubber and dilute the viscosity of silicone rubber, you can add diluent or cross-link the silicone rubber. For MS and STP-E silicone rubber, because they have a certain elasticity, and 107 silicone rubber, because of its larger molecular weight, can be dissolved by adding solvent-free high-functional silicone resin;

High-functionality silicone resin and silicone rubber can adjust the viscosity and mechanical properties of silicone rubber by cross-linking the silicone rubber. And the effects achieved by using solvent-free silicone resin for dilution or reinforcement include the following:

1. Increase the viscosity of silicone rubber: By using high-functionality silicone resin, a three-dimensional network structure can be formed in the silicone rubber to increase the viscosity of the silicone rubber. This increase in viscosity is very useful for certain areas that need to be filled with silicone rubber, such as automotive parts, building seals, etc.

2. Enhance the mechanical properties of silicone rubber: High-functionality silicone resin can form chemical bonds with the polymer chains in silicone rubber, thereby improving the mechanical properties of silicone rubber. This enhancement effect can improve the tensile strength, tear strength and wear resistance of silicone rubber, allowing it to maintain good performance in various harsh environments.

3. Reduce the cost of silicone rubber: Using solvent-free silicone resin for dilution or reinforcement can reduce the use of organic solvents in silicone rubber, thereby reducing production costs. Solvent-free silicones have low volatility, reducing environmental pollution and health concerns.

4. Improve the production efficiency of silicone rubber: Using high-functionality silicone resin can make the silicone rubber complete the vulcanization process faster, thus improving production efficiency. Due to the increased viscosity of silicone rubber, processing operations such as filling and molding can be performed more easily, improving production efficiency.

5. Improve the weather resistance of silicone rubber: High-functionality silicone resin can form chemical bonds with the polymer chains in silicone rubber, thereby improving the weather resistance of silicone rubber. Silicone rubber can maintain good performance and appearance even under harsh environmental conditions, such as high temperature, ultraviolet radiation, etc.

Different silicone rubber varieties have different physical and chemical properties, which need to be adjusted and optimized according to specific circumstances when performing operations such as dissolving, diluting, cross-linking and adding fillers. It is also necessary to pay attention to safety issues, such as avoiding the use of toxic and harmful solvents and additives, and avoiding the generation of harmful gases and waste.
