Liquid Silicone Rubber, abbreviated as LSR in English, is a product favored by consumers and manufacturers. It has good elasticity, waterproof and moisture resistance, and is resistant to acid, alkali and other chemical substances, so it is generally used to replace life. plastic supplies. Liquid silica gel is divided into A glue and B glue, the ratio of the two is controlled by a quantitative device to be 1:1, and then fully mixed through a static mixer, injected into the injection tube, and then produced by injection molding.

Properties of Liquid Silicone

LSR is a non-toxic, heat-resistant, high-recovery flexible thermoset material with excellent transparency, tear strength, resilience, yellowing resistance, thermal stability, good air permeability, heat aging resistance and weather resistance sex. Its rheological behavior is mainly characterized by low viscosity, fast curing, shear thinning and high thermal expansion coefficient. LSR is a dual-liquid rapid vulcanization material with platinum as a catalyst, which can be produced by injection molding, mass, rapid vulcanization, and repetitive mechanical production.

Its characteristics are as follows:

1. Wide temperature range: -50℃-250℃

2. Stable mechanical and electrical properties in a wide range of temperatures

3. It has stability in any weather and UV irradiation, anti-aging

4. High insulation: dielectric strength ≥ 20kV/mm

5. Burning to release non-toxic gas

6. Fast curing speed, about 10 times that of conventional solid silica gel

7. It can stand in the barrel for a long time under low temperature environment

8. Good connection can be obtained by combining with PA, PA6, PA66, PBT, PC, PPS and other materials
