TPV (Thermoplastic Polyolefin Vulcanisate) is a mixture of a polyolefin-based plastic (usually PP) and an elastomer such as EPDM. Unlike TPO, the elastomer in TPV is cross-linked or vulcanized.
By vulcanising elastomers into TPV, TPV comes closest to traditional rubber in terms of its mechanical properties. This is particularly evident in the excellent compression properties. In addition, TPV boasts above-average temperature resistance.
This makes TPV ideal for static and semi-static seals requiring a low compression set where TPS no longer meets the temperature characteristics.
