Impact improvement of Polypropylene

The flexibility, the exceptional mechanical properties and unique compatibility of Exact plastomers can be applied in minority blends with polypropylene to improve the (cold) impact resistance of articles produced by either injection moulding, blow moulding or thermoforming.

Blow moulded bottle drop test / Haze Drop height at 4°C for 1.5 MFR RCP / 902 D Exact blend  Drop height at -20°C for 1.5 MFR RCP / 882 D Exact blend Haze of RCP / 882 D Exact blend

This is of particular benefit in clear PP articles, where impact resistance can be enhanced while retaining the optical quality of the polypropylene.

This concept offers flexibility in operations. With a single blend component the PP (cold) impact resistance can be varied according to the demands of the application, thus allowing cost optimization and rationalization of logistics.
