Abstract: Thermoplastic compositions comprise non-fluorinated hydrophobic additive comprising fatty acid ester, hydrolysis stabilizer comprising at least one of polycarbodiimides and polyester-modified siloxanes, and thermoplastic polymer. The combination of the non-fluorinated hydrophobic additive and the hydrolysis stabilizer results in thermoplastic compositions having improved hydrophobicity and/or enhanced durability of hydrophobicity while also being free of fluorine and fluorinated substances.

Abstract: Overmolded thermoplastic articles include a base component comprising rigid thermoplastic material and an overmold component comprising recovered thermoplastic elastomer material. The recovered thermoplastic elastomer material includes, based on weight of the recovered thermoplastic elastomer material, greater than or equal to about 97 wt % of antecedent thermoplastic elastomer material and less than or equal to about 3 wt % of antecedent rigid thermoplastic material. The recovered thermoplastic elastomer material is obtained from an antecedent separation process in which the antecedent thermoplastic elastomer material is separated from at least a portion of the antecedent rigid thermoplastic material.
