PE-BASED CROSSLINKED ELASTOMERIC FOAM WITH HIGH FILLER LOADINGS FOR MAKING SHOCKPADS AND ARTICLES USED IN FOOTWEAR AND FLOORING APPLICATIONS

摘要

Crosslinked foams having high filler loadings, which may be formed from A) a polyolefin having a crystallinity of 21 percent or less, an ethylene vinyl acetate copolymer having a vinyl acetate content of less than 15 mole percent, or a combination thereof; B) a polyolefin having a viscosity between 500 and 20,000 cP, as measured using ASTM D1084 (Brookfield Viscosity at 350° F.); and C) a filler, wherein the crosslinked foam includes from 10 to 80 parts filler per hundred parts of components A, B, and C, by weight. In other aspects of embodiments disclosed herein, the crosslinked foam may optionally include one or more of: D) at least one polyolefin having a crystallinity of greater than 21 weight percent, an ethylene vinyl acetate copolymer having a vinyl acetate content of 15 mole percent or greater, or a combination thereof; and E) a scorch retarder.
