  • FOAMS MANUFACTURED USING SILICONE-FUNCTIONALIZED POLYETHYLENE AND METHODS OF MAKING THE SAME
    Publication number: 20230365771
    Abstract: According to various embodiments, an extruded foam is formed from a composition comprising from 1 to 99 wt % of a silicone-functionalized polyethylene comprising a reaction product of the polymerization of ethylene and (meth)acrylic ester functionalized polydimethylsiloxane, and a physical blowing agent. The foam has a density of less than or equal to 0.200 g/cm3 as measured in accordance with ASTM D1622-88 at 25° C.
