Abstract:
A thermoplastic elastomer composition comprising an elastomer polymer, a thermoplastic polymer, a mineral, and a flexural modulus modifying agent, wherein said flexural modulus modifying agent increases the flexural modulus without substantially affecting the impact resistance relative to the composition in the absence of said flexural modulus modifying agent and said flexural modulus modifying agent is selected from the group consisting of polysiloxanes, polyols, fatty acids, fatty acid amines, fatty acid amides, polyether polyols, glycols, fatty acid esters, alkyl sulfonates, aryl sulfonates, in situ calcium stearate in wax and mixtures thereof; andand wherein said composition has a flexural modulus increase of at least about 15% relative to the composition in the absence of said flexural modulus modifying agent.
