TPO (Thermoplastic Polyolefin) is a blend of a polyolefin-based plastic (mostly PP) and an elastomer such as for example EPDM. In contrast to TPV, the elastomer in TPO is not or only slightly crosslinked.
TPOs are polymer mixes. Depending on their composition, TPOs can be made to be either hard or soft. Hard TPOs, in which PP and talc make up around 75% of the whole, are often used as impact-enhanced plastics.
Soft TPOs contain a clear higher percentage of elastomer: up to 70%. An advantage of TPOs as compared to other thermoplastic elastomers is that TPO is usually less expensive. Uses of soft TPOs include roofing and they are UV-resistant.
Typical properties of TPO are:
