High-purity polypropylene recyclates

Abstract

The present disclosure relates to a polymer composition, preferably a melt-processed polymer composition, comprising at least 95 wt %, based on the total weight of the polymer composition, of a post-consumer recycled polypropylene resin, the polymer composition having an ethylene content (C2(CF)) of the crystalline fraction (CF), in the range of from [C2−3.4] to [C2−0.2] wt %, preferably from [C2−3.0] to [C2−0.6] wt %, more preferably from [C2−2.4] to [C2−1.2] wt % of the total weight of the crystalline fraction of the polymer composition, as determined by Crystex analysis as described in the specification; and a heat deflection resistance of at least 97° C., preferably in the range of 97° C. to 110° C., more preferably in the range of 98° C. to 105° C., determined with DMTA as described herein and expressed by the temperature at which the storage modulus E′ of 400 MPa is reached (T(E′=400 MPa)). The present disclosure further relates to the use of the polymer composition, preferably the melt-processed polymer composition, in the manufacture of an article, and to a respective article.
