Unique chemical structure and performance basis
Liquid silicone rubber (LSR) belongs to the silicone family and has a very unique chemical structure. The main chain is composed of alternating silicon-oxygen bonds (Si-O), which have high bond energy and give the material excellent thermal and chemical stability. The side chains are organic groups, such as methyl and vinyl, which give silicone rubber different properties. Methyl can enhance hydrophobicity, while vinyl plays a key role in the cross-linking reaction, allowing liquid silicone rubber to transform from a fluid state to an elastic solid state.
Excellent performance opens up a variety of applications
Elasticity and flexibility: Liquid silicone rubber exhibits excellent elasticity after curing, with excellent resilience, and can be repeatedly stretched and compressed without deformation. This makes it widely used in the field of seals, such as automotive engine sealing gaskets, which can fit tightly to parts to prevent liquid and gas leakage, while buffering vibration and pressure and extending the life of parts.
Biocompatibility: It has good biocompatibility, is non-irritating and non-toxic to human tissues, and does not induce immune responses. In the medical field, it is often used to manufacture implantable medical devices, such as pacemaker insulation sleeves, artificial breast prostheses, etc., to ensure human health and safety.
Thermal stability: It can maintain stable performance in the temperature range of -50℃ to 250℃, does not decompose or soften at high temperatures, and does not become brittle at low temperatures. In the electronics and electrical industry, it is used to manufacture packaging materials for electronic components that work in high-temperature environments, such as electronic components inside ovens and microwave ovens, to ensure stable operation of the equipment.
Liquid silicone rubber has become an indispensable material in modern industry and daily life due to its unique chemical structure and excellent performance. With the development of technology, its application areas will continue to expand.
