Abstract
The present invention provides a mineral filled thermoplastic olefin (MFTPO) composition comprising a polymer mixture, a mineral and a flexural modulus modifying agent and/or a heat deflection temperature modifying agent, and a method for producing the same. The flexural modulus modifying agent and/or a heat deflection temperature modifying agent significantly increases the flexural modulus and/or a heat deflection temperature of the MFTPO without substantially affecting the falling weight impact resistance of the MFTPO relative to a similar MFTPO composition which lacks the flexural modulus modifying agent and/or a heat deflection temperature modifying agent.
