Abstract
Scratch resistant polymer composition, in particular for the manufacturing of rigid, scratch resistant and dimensionally stable building bricks, comprising: a) a bio-based HDPE granulate, produced from ethanol or ethylene obtained from biomass; b) an amorphous polymer and/or (semi)crystalline polymer; c) optionally a mineral filler and optionally a colouring pigment; Furthermore, a method for manufacturing an injection moulding article from the scratch resistant polymer composition is disclosed.
Claims14
Scratch resistant building bricks or other pieces of toys obtained by injection moulding a polymer composition consisting essentially of:
- a) a bio-based HDPE granulate, produced from ethanol or ethylene obtained from biomass;
- b) an amorphous and/or (semi)crystalline polylactic acid (PLA) based polymer;
- c) a mineral filler in an amount in the range from about 5 wt % to 40 wt %, based on the total polymer composition, and optionally a colouring pigment.
