LAMINATE OF A SUBSTRATE AND AN EXTRUDED HIGH DENSITY POLYETHYLENE LAYER

摘要

A laminate (12) of an elastomeric substrate (18) and a high density polyethylene layer having certain properties is disclosed. The preferred hig h density polyethylene has a density of from 0.940 to 1.000 g/cm3, a melt inde x of less than 10 grams per 10 minutes under conditions of 190 ~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 ~C and 21.6 kg load and 2,982.2 kPa pressure. The laminate (12) is particularly well suited for use in automotive seals.
