A laminate of an elastomeric substrate and a high density polyethylene having certain properties is disclosed. The preferred high density polyethylene has a density of from 0.940 to 1.000 g/cm , a melt index of less than 10 grams per 10 minutes under conditions of 190&deg; C. and 2.160 kg load and 298.2 kPa, and a melt index of greater than 5 grams per 10 minutes under conditions of 190&deg; C. and 21.6 kg load and 2,982.2 kPa pressure. The laminate is particularly well suited for use in automotive seals.

Disclosed is a method of preparing a blended thermoplastic resin composition that includes combining a ground crosslinked rubber with a thermoplastic material and a compatibilizer, and the products formed thereby. The ground crosslinked rubber has an average particle size of about 80 mesh or smaller. The thermoplastic material can be a polyolefinic resin or a polyolefinic elastomer or olefinic vulcanizate elastomer. The ground crosslinked rubber is included in amounts of up to 70% by weight, based on the total weight of the blended thermoplastic composition.
