Thermoplastic vulcanizates

Thermoplastic vulcanizates(TPV’s) are a very special class of TPE prepared by dynamic vulcanization or cross-linking process of PP and EPDM rubber,

It builds favourable properties which make it high performance polymer, compressible and heat resistance.

TPV seen strong growth in automobile seals, pipe seals, wire & cable jacketing compound and other application where a high heat resistance required. Thermoplastic vulcanizates with excellent properties of heat resistant and breaking strength.
