The applicability of “Grace” Rubber Goods
› The applicability of “Grace” Rubber GoodsCurrently our company works with more than 40 grades of rubber compounds, composition of which was developed by leading Russian and Ukrainian research institutes with the optimal recipe-technological parameters correlation, what in its turn guarantees continuous rubber goods operation in different exploiting ambients and within a vast range of temperature: from minus 70º С to plus 300º С.
Our specialists in elastomer goods will select a rubber compound, which fully satisfies Your requirements. A table below illustrates usage of various rubber compounds types, used at our company for all kinds of rubber goods production.
