HiPrene® MM71T is a mineral filled, impact modified polypropylene compound suitable for injection moulding. This material has been developed especially for Thin Layer highly demanding aesthetic automotive application, with perfect scratch resistance and UV stabilization. It is especially suitable for car interior applications requiring ductility, because of its high impact resistance with lesser sharp edge crush during the crush test in car and requiring very high scratch resistance because of location in the car interior. This material is available in natural or color-matched, pellet form.
