In most cases, producers have entirely passed on the steep cost increase caused by a styrene monomer reference that leapt up €190/t ($224) in September. For ABS and especially for EPS, where the market was characterised by supply shortage, many suppliers additionally topped the premiums with increased margins.

The roller coaster ride of styrenics prices continues. In October, the styrene monomer reference contract fell by €110/t ($129). At least PS and EPS prices are likely to plummet again in the wake of this decrease.
