Two or more polyolefin elastomers selected from the group consisting of dense, micro-dense and dynamic silane-crosslinked polyolefin elastomers having densities of less than 0.90 g / cm 3, less than 0.70 g / cm 3 , and less than 0.60 g / cm 3 , respectively. A combination sealing member comprising a composition is provided. The combined sealing member exhibits a compression set of about 5.0% to about 35.0% as measured according to ASTM D 395 (22 hours at 70 ° C.). |
