TPV

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.

A whole range of possibilities...

The Dryflex XL range of TPV compounds contain a highly cross-linked elastomeric phase dispersed in a thermoplastic mix. The cross-linked phase provides improved elasticity and thermal stability and the thermoplastic phase provides the melt-processability.

All Dryflex XL TPV compounds offer superior weathering and ozone resistance characteristics; they display excellent colour and property retention after excessive exposure to UV.
