PP Impact Copolymer

PP impact copolymer for crates, pails, automotive and thin-wall parts that must stay tough at low temperature. Send an RFQ.

PP impact copolymer grades

Impact copolymer (also called block copolymer or PP-B) contains a dispersed ethylene-propylene rubber phase. It keeps its impact strength down to about -20 °C, at the cost of some stiffness and clarity.

Grades are chosen by the balance of flow, stiffness and impact needed for the part.

Choosing an impact copolymer

Crates, pails and boxes: MFR 10–20 g/10 min with high impact strength.
Thin-wall food packaging: MFR 40 and above for fast filling of thin walls.
Automotive parts: Medium-flow grades, often as the base for talc-filled compounds.
Battery cases and luggage: Low-flow, high-impact grades.

Typical applications

Crates, pails and buckets
Thin-wall food containers
Automotive bumpers and interior trim
Battery cases
Luggage and garden furniture

Processing notes

No drying needed. Typical melt temperature is 200–250 °C. Shrinkage is slightly lower than homopolymer; parts can stay white at stress points (stress whitening) if bent sharply.

General guidance only; follow the producer's TDS for each grade.

PP Impact Copolymer: common questions

Impact copolymer or homopolymer for a crate?

Impact copolymer. Crates are dropped and stored cold, which is where homopolymer cracks.
