Crosslinkable elastomeric compositions including sustainable content, articles made therefrom, and methods of making the same

Abstract

A crosslinkable material includes 10 wt. % to 80 wt. % of a silane-grafted ethylene-based elastomer, 10 wt. % to 80 wt. % of a silane-grafted propylene-based elastomer, and 10 wt. % to 40 wt. % of a silane-grafted polyethylene homopolymer, based on a total weight of the crosslinkable polymer material. In various embodiments, a crosslinkable silane-grafted polyolefin composition including the silane-grafted ethylene-based elastomer, the silane-grafted propylene-based elastomer, and the silane-grafted polyethylene homopolymer is formed by reacting an ethylene-based elastomer, a propylene-based elastomer, a polyethylene homopolymer, a vinyl silane, and an organic peroxide. Also provided is a crosslinkable thermoplastic composition including the reaction product of the crosslinkable material with 0.5 wt. % to 8 wt. % of a crosslinking catalyst, based on a total weight of the crosslinkable thermoplastic composition. According to some embodiments, cured articles formed from the crosslinkable thermoplastic composition are thermoset articles, having excellent compression set properties.
