Liquid silicone rubber for injection molding (LSR) is a new type of silicone material with non-toxic, odorless, excellent weather resistance and chemical inertia. It is one of the high-grade silicone products which developed rapidly in recent years. This kind of silicone rubber has low viscosity (it has certain fluidity and unfinalization before vulcanization), and can be fed by metering mixing equipment, and the two components are mixed and injected by special injection molding equipment, and then quickly vulcanized and molded products.

Compared with traditional materials, liquid injection molding silicone rubber has many advantages: short molding cycle, high degree of automatic molding, low vulcanization temperature, no by-products in the vulcanization process, high precision of generated products, no edge repair and long service life of products, etc.

The special material properties of liquid silicon are solidified only by crosslinking. Interestingly, LSR is always applied where conventional and thermoplastic synthetic rubber (TPE) reaches its limits. LSR also has very good resilience, high heat resistance (some over 180°C), low temperature flexibility (minimum about -50°C), high electrical insulation properties, tensile and rebreaking strength, and is physiologically harmless.

From silicone, silicone rubber raw materials, product classification, the application characteristics of liquid silicone raw materials as well as the matters needing attention to distinguish, will have their own different, the continuous development of the research, the silica gel in the modern industrial fields have begun to become increasingly widely used, for example, health care, baby and child care, smart apparel, automobile and aerospace and other fields. Familiar with silicone raw materials, liquid silicone rubber raw materials application technology and main applications, will help us to deeper and wider to discover, research and exploration.
