Claim 19:
20. The thermoforming process as claimed in claim 1, wherein the foamable layer is based on a polymer composition comprising
a) from 35 to 45 parts by weight of the at least one thermoplastic vulcanizate (TPV), wherein the thermoplastic phase of the TPV is based on polypropylene and the vulcanized elastomer phase of the TPV is based on ethylene-propylene-diene elastomer (EPDM);
b) from 15 to 25 parts by weight of the at least one high melt strength polyolefin (HMS polyolefin), wherein the at least one high melt strength polyolefin is a high melt strength polypropylene; and,
c) from 35 to 45 parts by weight of the at least one low density polyethylene (LDPE); and
wherein the density of the foam layer is more than 500 kg/m 3 and less than 800 kg/m3.
