Whether rain sensors or plug connectors in the automotive sector, optical pulse measurement or baby pacifiers in medical technology – injection moulded parts made of liquid silicone or liquid silicone rubber (LSR) are used in a wide variety of applications. This material is a full 30 years old.
Injection molding liquid silicone rubber (LSR) is a new type of silicone material that is non-toxic and tasteless, with excellent weather resistance and chemical inertness. It is one of the high-grade silicone products that has developed rapidly in recent years. This type of silicone rubber has low viscosity (it has a certain fluidity and shapelessness before vulcanization), and can be fed by metering and mixing equipment, and the two components are mixed and injection molded by special injection molding equipment, and then quickly vulcanized to form products. .
Compared with traditional materials, liquid injection molding silicone rubber has many advantages: short molding cycle, high degree of automated molding, low vulcanization temperature, no by-products in the vulcanization process, high precision of the resulting product, no need for trimming, and long service life of the product. A replacement for popular synthetic rubber materials and high-end applications.
The special material properties of liquid silicon are only cured by crosslinking. Interestingly, where conventional and thermoplastic synthetic rubbers (TPE) reach their limits, LSR is always applied. LSR also has very good resilience properties, high heat resistance (some over 180 °C), low temperature flexibility (minimum about -50 °C), high electrical insulating properties, tensile and re-breaking strength, and physiologically Harmless. These material properties, single dyeing, and ability to combine with a variety of metals and plastics make liquid silicon desirable for a wide range of applications. Coupled with the increasing number of material types. For example: in addition to the standard types of various Shore hardness, there are also medical technology, oil resistance, thermal dialysis of oil, electrical conductivity, flame retardant, fast crosslinking or adhesion modification and made of silicon fluoride. type.
From the product classification, application characteristics and precautions of silica gel, silicone rubber raw materials and liquid silica gel raw materials, there will be their own differences. For example: medical, infant care, smart wear, automobile, aerospace and other fields. The application technology and main application uses of silicone raw materials and liquid silicone rubber raw materials are familiar, and we can discover, research and explore more.
