Abstract
A method of manufacturing an article by injection moulding is disclosed, the method comprising injection moulding an article from a polymer resin, wherein the polymer resin comprises different types of recycled polymer and a compatibilizer comprising inorganic particulate material and a surface treatment agent on a surface of the inorganic particulate material, and wherein the polymer resin has a MFI @ 2.16 kg/190° C. of equal to or greater than 3.0 g/10 min. Further disclosed is the use of a compatibilizer in an article or in a polymer resin, a polymer resin suitable for use in the manufacture of an article therefrom by injection moulding, and an article so produced.

A polymer resin suitable for use in injection moulding, the polymer resin comprising a mixture of different recycled polymers and from about 5 wt. % to about 20 wt. % compatibilizer comprising inorganic particulate material and a surface treatment agent on a surface of the inorganic particulate material, based on the total weight of the polymer resin,
- wherein the polymer resin has a MFI @ 2.16 kg/190° C. of equal to or greater than 3.0 g/10 min, and
- wherein the polymer resin comprises at least about 50 wt. % recycled polyethylene, based on the total weight of the polymer composition, and from about 10 wt. % to about 30 wt. % recycled polypropylene, based on the total weight of the polymer resin.
