ETHYLENE PROPYLENE RUBBER-BASED BLEND

摘要

PURPOSE:To obtain the subject blend, capable of preventing bleeding due to a softener from occurring and suitable as molding materials for automotive rubber products such as weather strips by blending a polymer component with the softener and a hydrous magnesium silicate-based clay mineral in a specific proportion. CONSTITUTION:The objective composition obtained by blending 100 pts.wt. polymer component with >=5 pts.wt. softener and further blending the resultant ethylene propylene rubber-based blend with a hydrous magnesium silicate-based clay mineral (e.g. sepiolite or palygorskite) in an amount of 0.05-0.5 based on the aforementioned softener.
