Silicone is a synthetic polymer. Its molecular structure is distinctive. The molecules are comprised of silicone atoms which are bonded to each other via oxygen atoms. This combination of a typically inorganic structure and organic components makes silicone a unique type of material the special characteristics of which cannot be achieved by any other plastic.

Silicones can be subdivided into different groups. While silicone oils and resins are, for instance, used to produce paints, silicone rubbers are used for endless belts. They are used in both wet and dry areas and can – in combination with the right carcass – be used in extreme cold, down to -50°C, and extreme heat, up to +300°C.

Silicones are very well suited for direct contact with food and for hygiene applications since they are recognized as physiologically safe. The latter fact is underlined by the increased use of silicone in cooking utensils. Another characteristic to be highlighted for the material’s use as belt coating is its toughness which results in very good abrasion resistance while offering a high friction coefficient. Silicones have good chemical stability, are UV-resistant, and do not become brittle.
