Thermoplastic vulcanisates (TPV or TPE-V)
TPV compounds are the next step up in performance from TPO. These too are compounds of PP and EPDM rubber, however they have been dynamically vulcanised during the compounding step. They were originally conceived to bridge the gap between thermoplastic materials and vulcanised EPDM.
They have seen strong growth in EPDM replacement for automotive seals, pipe seals, and other applications where a heat resistance of up to 120degC is required. Shore hardness values range typically from 45A to 45D. TPVs also lend themselves to under-bonnet automotive applications where improved temperature and oil resistance is required.
