Product Description
Moplen EP548L is a heterophasic copolymer suitable for production of beverage closures using both compression and injection moulding technologies. This resin offers a good balance of stiffness and impact strength. The resin is nucleated and additivated with both slip and antistatic agent. Other injection moulding applications may include housewares and medium size containers.
