Sidistar® in FKM
Improving special compounds
FKM
FKM elastomers are a special case in the rubber world. Unlike other rubber compounds, Sidistar® - with its very low specific surface of 20-30m2/g- acts as a reinforcing filler for FKM elastomers.
Sidistar® is capable of replacing N990 on a 1:1 basis. Physical properties will remain very similar, dynamic fatigue properties will improve. Since Sidistar® also has grades with an off-white colour, it allows to produce coloured FKM compounds without compromises on physical properties.
