Polytrope(reg) thermoplastic elastomers (TPOs) are typically blends of polypropylene, EPDM rubber, fillers, and additives yielding a wide range of properties. Most notable for their low specific gravity and low-cost raw materials supply base, thermoplastic elastomers provide a cost/performance ratio for automotive applications. TPOs can be compounded to possess a comprehensive range of physical properties from soft and rubber-like to hard and rigid.
