Properties of Silicone

The unique properties of silicone cover a large number of functions. The most noticeable is the excellent temperature resistance. Silicone is stable at -90-330°C. This rather wide range contrasts with most organics, which begin to solidify above 0°C and begin to fade and oxidize at 120°C. Due to its inherent ultraviolet (UV) and oxidation resistance, silicone is very weather resistant, so it is very suitable for outdoor use. Silicones do not discolor and cleave over time as organics do.
The electrical insulation performance of silicone resin is close to that of glass products, so it is also perfect for electronic products. In addition, special ozone resistance and corona resistance make it possible to use it in high-pressure applications. Silicones provide good water resistance and water stability, so they can also be found in the field of underwater instruments. As a kind of rubber, silicone resin is used in the field of gaskets and seals due to its high resistance to compression deformation. Its own bonding ability is used for the conveyor belt of the oven for baking food, and can also be used for elastic molds for injection molding materials and low melting point alloys.
Silicone's exceptional UV resistance allows it to be used in high-energy lighting, instrumentation and solar installations. In the 1950 s and 1960 s, the subject of a large number of artificial hearts was studied, and since then, the biocompatibility of silicone has led to its use in a variety of implants, wound care and drug delivery systems.
