Styrene Monomer

Inhibited styrene monomer for polystyrene, ABS, SBR and resin production.

C₈H₈ CAS 100-42-5 Base Chemicals

01 Overview

Styrene monomer is the feedstock for polystyrene, ABS, SBR latex and unsaturated polyester resins. It polymerises spontaneously under heat and requires TBC inhibition and temperature-controlled storage — this is the defining commercial and operational consideration in every SM trade.

06 Packaging options

  • Bulk vessel parcels
  • ISO tank (24 MT)
  • 180 kg steel drums

07 Supply & export note

Every consignment is supplied with certified TBC content and a production date. We plan transit duration and ambient exposure against the inhibitor level, and will advise against a route where the transit time places the cargo at polymerisation risk.
