Description
Moplen EP548S is a nucleated heterophasic polypropylene copolymer formulated with an antistatic additive for injection-molding applications. The grade combines high fluidity with a balanced combination of stiffness and impact performance.
Its high flow supports efficient mold filling, particularly in thin-wall components, while its mechanical-property balance makes it suitable for durable consumer products, opaque containers, and packaging applications.
Typical uses include housewares and opaque thin-wall food containers such as margarine tubs and yogurt cups. Food-contact compliance should be confirmed through the current manufacturer documentation for the intended market and end-use application.
