The molecular chains then have a nature both organic and inorganic.<\/p>\n<p>Silicone rubbers are odorless, tasteless and non-toxic. When formulated and manufactured correctly, it is not staining or corrosive or deteriorating of any material with which it is contacted. They are physiologically inert and this has led to a wide variety of applications in the field of medicine. They are absolutely unalterable by ozone, weathering and ultraviolet radiation.<\/p>\n<p>They have comparatively low mechanical properties with other rubbers (breaking load, elongation and tear) although it keeps them constant even at high temperatures. However, it is not advisable to subject them to steam under pressure. They are considered among the elastomers as the best electrical insulators.<\/p>\n<p>The most outstanding quality of this rubber is its resistance to temperature: its compounds can work for extended periods of time in temperatures of up to 350\u00baC. On the other hand, in extreme cold conditions, this material will retain its original elasticity and flexibility.
