WebRTV silicone (room-temperature-vulcanizing silicone) is a type of silicone rubber that cures at room temperature. It is available as a one-component product, or mixed from two-components (a base and curative). Manufacturers provide it in a range of hardnesses from very soft to medium—usually from 15 to 40 Shore A. RTV silicones can be cured with a … Web(b) Vulcanized rubber has a network structure with cross-links. (c) Vulcanized rubber on stretching. The covalent cross-links survive the stretching and help the molecules to spring back once the tension has been relaxed. This type of network molecular structure lies behind the explanation of why rubber is rubbery.
