Abstract
A thermoplastic polymer formulation that contains polyamides (PA) and/or EVOH and polyolefins, in particular with polyamides (PA) and/or EVOH that derive from production waste of multilayer films, also comprises polypropylene homopolymer with MFI in the range of 15 to 50 (g/10 min, ASTM 1238L) as compatibilizer between the PA and/or EVOH and polyolefin polymers.
Claims18
A thermoplastic polymer formulation containing polyamides (PA) and/or EVOH and polyolefins, characterized in that it also comprises polypropylene homopolymer with MFI in the interval within 15 to 50, preferably 20 to 50, (g/10 min, ASTM 1238L), as a compatibilizer between said PA and/or EVOH and polyolefin polymers.
A formulation according to 1, further comprising a PP filled with inorganic and/or organic fillers, said filled PP being present in a quantity between 15% to 40%, preferably 25% and 35% by weight of the final formulation weight.
Use of a polypropylene homopolymer having MFI in the range of 15 to 50, preferably 20 to 50 (g/10 min, ASTM 1238L) as a compatibilizing polymer between two or more polymers selected from PE, PA, PP, EVOH and blends thereof.
