Liquid silicone rubber base is a fumed bassd with moderate viscosity and high transparency. it is mainly a base material that mixes vinyl silicone oil and fumed silica well after being treated with special additives at medium and high temperatures. It is mainly used in: By adding hydrogen-containing silicone oil,inhibitors, platinum catalysts and other types of silicone oil to the base rubber and making reasonable distribution to make AB two-component addition-type liquid silicone rubber, customers can make various products such as baby pacifiers, swimming supplies, mold silicone and calendered foam silicone sheets through injection molding.
Application:
1. Liquid silicone rubber for baby products;
2. Liquid silicone rubber for sports products;
3. Liquid silicone rubber for medical products
4. Liquid silicone rubber for power and communication products;
5. Liquid silicone rubber for injection molding of adult products;
6. Liquid silicone rubber for various household appliance seals and other miscellaneous products;
7. Injection or compression molding of two-component simulated diamond mold silicone;
8. Calendering molding of two-component foam silicone for foamed silicone sheets.
Features:
1. High transparency;
2. Excellent tear strength;
3. Automatic line production, higher efficiency, lower cost;
4. Compared with the traditionally prepared base glue, the volatile content is lower; Environmental protection and non-toxic, can reach medical level;
5. Temperature resistance -50C~200°℃.
