European PP producers would have liked to raise their prices by considerably more than the €40 ($47) per tonne increase in the propylene reference contract that resulted in September 2017. They only managed to do so, however, in cases where prices were at a particularly low level.

Producers generally achieved moderate gains, while doing somewhat better with copolymers that were tending short. Buyers exercised too much restraint for any more, feeling that prices were running high.

In October, prices were set to follow the propylene reference contract once more, which has undergone a moderate rise again. The slight bottlenecks in September are being resolved and buyers are no longer necessarily under pressure to act.
