Method for increasing the wet coefficient of friction of a thermoplastic elastomer and composition therefor

摘要

A method for increasing the wet coefficient of friction of a thermoplastic elastomer includes adding various ingredients to the thermoplastic elastomer. In one embodiment microcrystalline wax, amorphous polyalphaolefin ethylene copolymer, and a copolymer ethylene/propylene and olefins are added to the thermoplastic elastomer. And in another embodiment, microcrystalline wax and copolymer ethylene/propylene and olefins are added to the thermoplastic elastomer. The above compositions are formed into a sheet which can be used alone as a slip-resistant pad, or can be applied to a desired surface (such as that of a surfboard).

主权项

1. A composition, comprising:
a thermoplastic elastomer being about 83.3 to about 93 weight percent; a microcrystalline wax being about 2.3 to about 8.3 weight percent; an amorphous polyalphaolefin copolymer which includes about 15 weight percent ethylene and 85 weight percent propylene, said amorphous polyalphaolefin copolymer being about 2.3 to about 4.3 weight percent; and, an ethylene propylene copolymer wax having a weight average molecular weight of about 650, and having a melting point of about 96° C., said ethylene propylene copolymer wax being about 2.3 to about 8.3 weight percent.
