Abstract
A blow molded article comprising a housing defining a hollow interior. The housing comprises a blow molded thermoplastic polymer and a thermoplastic elastomer on a portion of the blow molded thermoplastic polymer. The thermoplastic elastomer is polar and hydrophilic. A coefficient of friction of the thermoplastic elastomer when wet is higher than a coefficient of friction of the blow molded thermoplastic polymer when wet.
Claims17
A blow molded article comprising:
- a housing defining a hollow interior, the housing comprising:
- a blow molded thermoplastic polymer;
- and
- a thermoplastic elastomer on a portion of the blow molded thermoplastic polymer, wherein the thermoplastic elastomer is polar and hydrophilic and a coefficient of friction of the thermoplastic elastomer when wet is higher than a coefficient of friction of the blow molded thermoplastic polymer when wet, the thermoplastic elastomer has a coefficient of friction from about 2.0 to about 3.5 when wet with water and a Shore A hardness of about 35 to about 50.
