What is TPO

Print Page

Thermoplastic Polyolefins (TPO or TPE-O)

TPO compounds are resin blends of polypropylene (PP) and un-crosslinked EPDM rubber and polyethylene. They are characterised by high impact resistance, low density and good chemical resistance.

They are used in applications where there is a requirement for increased toughness and durability over the conventional PP copolymers, such as automotive bumpers and dashboards. The properties are restricted to the high end of the hardness scale, typically >80 Shore A and with limited elastomeric properties.

TPOs can be easily processed by injection moulding, extrusion or blow moulding.
