• Polystyrene (GPPS/HIPS/EPS), ABS/SAN copolymers. • Unsaturated polyester resins (UPR) / gelcoat reactive diluent. • SBR latex modification, resin & composite systems. |
• 200 kg steel drums (phenolic lined) • 1000 L IBCs
(specialty only). • Bulk road tanker / ISO tank / barge with inhibitor control. |
• UN 2055 Class 3 (flammable); polymerizes on
heat/peroxides — keep cool and out of sun.
• Ship and store **stabilized with TBC**. Do **not** nitrogen-blanket long-term; inhibitor requires oxygen. Maintain oxygen in headspace (≈ 5–8% v/v) and TBC within spec. • Recommended materials: 304/316L SS; avoid copper/brass and strong oxidizers. Never distill to dryness. |
Specs are representative; supply conforms to the COA for the lot
shipped. Choose inhibitor level to match your process residence
time and temperature profile.
