Product Description
Moplen EP332L is a heterophasic copolymer and is formulated with a highly effective heat
stabilisation package. It exhibits a good fluidity combined with a good balance of impact and stiffness as well as a low warpage tendency.
Moplen EP332L is applied in injection moulding applications requiring a good resistance to long term heat exposure, in particular for battery cases and automotive components.
Moplen EP332L is suitable for food contact. It is not intended for medical and pharmaceutical applications.
