Technical Datasheet EPC40R
Product Description:
Moplen EPC40R is a heterophasic polypropylene copolymer designed for injection moulding battery cases & technical items. The product offers an excellent balance of mechanical properties & process ability & features an excellent long-term heat–stability. Articles moulded with Moplen EPC40R offer a good balance of stiffness & toughness, good surface properties & a very high resistance to chemicals & crazing.
Applications:
Moplen EPC40R is largely used for automotive components.Battery cases, cooling water compensation reservoirs, brake fluid reservoirs, wash water reservoirs, dashboard supports, luggage compartment trims & door trim panels are typical applications. In the electro-technical industries, Moplen EPC40R is used for appliance, cables & wires (e.g. as slotted core element in fiber optic cables). Moplen EPC40R is suitable for food contact.
