From rain sensors to plug connectors in automotive, optical pulse measurements to baby pacifiers in medical technology, injection parts made of liquid silicon or liquid silicone rubber (LSR) have a wide range of applications. The material is 30 years old.

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. 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, long service life of products, etc. As a popular alternative to synthetic rubber materials and high-grade applications.

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. These material properties, the ability to dye alone and combine with a variety of metals and plastics make liquid silicon popular for a wide range of applications. Plus the increasing number of material types. For example, in addition to the various standard Shore hardness types, there are medical technical, oil resistant, oil thermal dialysis, electrical conductivity, flame retardant, rapid crosslinking or adhesion modification types, and types made of silicon fluoride.

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, through the continuous development of research, silica gel at the beginning of the application of modern industrial fields is increasingly widely used, such as health care, infant care, smart apparel, automotive, aerospace and other fields. Silica gel raw material, liquid silicone rubber raw material application technology and main application uses are familiar with, we can have more to discover, research and exploration.
