High Performance Filler for elastomers
Elastomers are form-solid but elastically deformable polymers, e.g. fluoroelastomers or silicones. These polymers are used wherever the high elasticity of the end product is important, such as in sealing rings, tires, cables, hoses, conveyor belts, floor coverings and in medical technology. Our fillers have a considerably positive influence on the mechanical properties (Shore hardness, modulus of elasticity, tensile strength, etc.) but also on the electrical properties (dielectric strength). In addition, they allow a very good colorability of the elastomer.

SIKRON® and SILBOND® successful in silicone
Silicone is an elastomer with unique properties: It is extremely elastic, very heat resistant, hydrophobic and comes with a high dielectric strength. In contrast to rubber, silicones maintain their properties over a large temperature range. Therefore, silicones are used for thermally stressed seals, insulations and plastics mouldings. Anyhow without these polymers medical technology, electronic industry and household applicances are impossible to imagine. In contrast to the needle-shaped wollastonite and platelet-shaped kaolin, silica and cristobalite are inert and due to their structure rather round and compact. In addition to the untreated types of the SIKRON® family the surface-treated SILBOND® -types are also available.
For seals and cables mainly silica is used, in particular the grade SIKRON® SF 600 and/or the coated types SILBOND® 600 TST and SILBOND® 600 RST. The treatment of the filler with trimethylsilane (-RST) provides a low viscosity during processing of the silicone. By using this filler the electrical and mechanical properties of the silicone part can be specifically influenced (e.g. increase of the electrical insulation behavior).
