Silicone rubber is an elastomer (rubber-like material) composed of silicone！itself a
polymer！containing silicontogether with carbon, hydrogen, and oxygen. Silicone rubbers are widely
used in industry, and there are multiple formulations. Silicone rubbers are often one- or two-part polymers,and may contain fillers toimprove properties or reduce cost. Silicone rubber is generally non-reactive,stable, and resistant to extreme environments and temperatures from ?55 ＜C to +300 ＜C while still maintaining its useful properties. Due to these properties and its ease of manufacturing and shaping, silicone rubber can be found in a wide variety of products, including: automotive applications; cooking,baking, and food storage products; apparel such as undergarments, sportswear, and footwear; electronics;medical devices and implants; and in home repair and hardware with products such as silicone sealants.
During manufacture heat may be required to vulcanize (set or cure) the silicone into its rubber-like
form. This is normally carried out in a two stage process at the point of manufacture into the desired
shape, and then in a prolonged post-cure process. It can also be injection molded.
