Structure-property relationships and applications of novel flexible TPO based on blends of developmental performance elastomer and polypropylene

Blends of developmental performance elastomers (DPE), produced by INSITE technology, and polypropylene exhibit a superior balance of flexibility and heat resistance. These blends provide a new family of flexible TPO that can be engineered to meet performance requirements of many applications. Generalized blend design strategies for flexible TPO based on thermodynamic considerations are reviewed. Thermal, dynamic mechanical and tensile properties of the blends will be presented. The utility and potential applications of these blends will be highlighted.
