LENHART, Robert J.
|Title:||POLYOLEFIN ELASTOMER COMPOSITIONS AND METHODS OF MAKING THE SAME|
An elastomeric article is provided that includes a composition having a silane-crosslinked polyolefin elastomer with a density less than 0.90 g/cm3. The elastomeric article can exhibit a compression set of from about 5.0 % to about 35.0 %, as measured according to ASTM D 395 (22 hrs @ 70 °C). The silane-crosslinked polyolefin elastomer can include a first polyolefin having a density less than 0.86 g/cm3, a second polyolefin having a crystallinity less than 40 %, a silane crosslinker, a grafting initiator, and a condensation catalyst.
