TPV are dynamically cured compounds, mainly of PP/EPDM. Cross-linked, dispersed EPDM in a thermoplastic phase of PP, has properties like- rubber and allowing at the same time, processing by conventional thermoplastics methods e.g. injection moulding. Saturated structure gives products of very good thermal stability, UV resistance, chemical resistance against :oils, solvent , and ozone in long time period. Very easy dyeability. Application : very wide range due to the resistance: including automotive and construction industries, electrical equipment, cables and seals out- working.
