Polyreflex thermoplastic polyolefin commonly referred to as TPO, it is a mixed material composed of polyolefin (PP or PE), rubber and certain fillers (talc, carbon fiber, etc.). These are members of the Thermoplastic Elastomer (TPE) family. They generally have good hardness, flexural fatigue, impact resistance and excellent resistance to certain chemicals. TPO is also highly resistant to UV radiation and extremes in temperature, making it ideal for outdoor use.
