Silicone rubber refers to a rubber whose main chain is alternately composed of silicon and oxygen atoms, and the silicon atoms are usually connected with two organic groups. It contains carbon, hydrogen, oxygen and silicon. There are a variety of formulations that can be found in two-part or single polymer. Some silicones contain fillers, which increase the properties of the silicone.
Silicones can be divided into three types:
·Solid silicone rubber (HTV)
·Liquid silicone rubber (LSR)
·Room temperature vulcanization (RTV)
Silicone rubber has excellent heat resistance, cold resistance, dielectric properties, ozone resistance and atmospheric aging resistance.
The outstanding performance is the wide operating temperature, which can be used for a long time at -60℃ (or lower temperature) to +250℃ (or higher temperature).
It has excellent physiological inertness, non-toxic, odorless, non-corrosive, transparent, easy to color, anti-coagulant, and good compatibility with the body.
Wide hardness range, 10-90 Shore hardness, chemical resistance, good sealing performance, resistance to compression deformation.
Compared with conventional organic elastomers, silicone rubber is also particularly easy to process and manufacture. Silicone rubber flows easily, so it can be molded, calendered, and extruded with low energy consumption.
Therefore, it plays a very important role in polymer materials and is widely used in aviation, cables, electronics, electrical appliances, chemicals, and other industries.
With the development of various industries, people have higher requirements for the application conditions, safety and health of products in different fields, and have higher requirements for the transparency and resilience of silicone rubber products.
