Mould Silicones

Unvulcanized silicone rubber consists of polymers of different chain length or polysiloxane chains. These polysiloxane chains always have a silicon-oxygen backbone. Two organic side-groups – usually methyl – are attached to each silicon atom. The polysiloxane chains determine the essential material properties possessed by all silicone rubbers. Examples are heat resistance and electrical characteristics.

Silicone rubbers consist essentially of silicone polymers and fillers. They undergo high-temperature (HTV) or room-temperature vulcanization (RTV) with suitable reactants, during which the uncured compound in a plastic state is transformed into an elastomeric rubber with a three-dimensional structure.

Silicone rubbers are heat resistant, low-temperature flexible and resistant to (UV, ozone and radiation) aging; they are easy to process and have good mechanical properties that remain unchanged over a wide temperature range. They are also reliable and environmentally compatible, with a neutral taste.

ELASTOSIL® silicone products, with their universal range of properties, find use in the most varied construction and industrial applications. Their near-to unlimited potential makes them ideal for applications in almost all industries – such as automotive and mechanical engineering, electronics and electrics, textiles, baby articles, toys, domestic appliances and sports articles, and as sealants in the construction industry.
