Abstract
Provided is an anti-slip pad with high coefficient of static friction, comprising a surface layer and a foamed inner layer, and having a coefficient of static friction of 0.58 to 1.4, which is determined by standard method ASTM D1894; and the anti-slip pad with high coefficient of static friction is prepared by injecting and molding a supercritical fluid blend obtained from a polymer material and a supercritical fluid; wherein the polymer material comprises a thermoplastic ether ester elastomer, a thermoplastic polyurethane or a combination thereof; the polymer material has elongation at break of 300% or more; the thermoplastic ether ester elastomer has a melt flow index at 230° C. of 20 g/10 min or less and Shore D hardness of 30D to 45D; and the thermoplastic polyurethane has a melt flow index at 205° C. of 25 g/10 min or less and Shore A hardness of 60A to 95A.
