Impact Copolymers

Impact copolymers are produced by the copolymerisation of ethylene with PP Homopolymer during a second reaction stage. This block type copolymerisation results in PP resins with the additional benefit of offering an excellent balance of impact strength and stiffness at both ambient and low temperatures.

With a wide range of melt flows, impact copolymers can be selected to perform in the most exacting applications, from the injection moulding of rigid thin-walled packaging for consumer and industrial segments and the extrusion of energy-saving pipes in construction to the moulding of interior and exterior applications for the automotive industry.

Impact copolymer resins are equally at home at high and low temperatures, so they are suitable for freezer and freezer-to-microwave applications.

Benefits

  • Stiffness and impact balance at ambient and low temperature
  • Excellent heat and chemical resistance characteristics
  • Excellent flow-ability and stiffness to impact ratio allow for moulding parts weight reduction and faster cycle times, leading to higher productivity
