Frequently Asked Questions
What is styrene monomer (SM) used for?
Styrene Monomer (SM) — also known as vinyl benzene, phenylethylene or ethenylbenzene — is a reactive aromatic monomer. Buyers use it for unsaturated polyester resin (FRP), polystyrene, SBR rubber, ABS resins, and coatings and composites.
What is the CAS number and HSN code for styrene monomer?
Styrene Monomer is CAS 100-42-5, HSN 2902 50 00. For transport it is classified UN 2055, Class 3 — flammable liquid and vapour.
What is TBC in styrene monomer, and why is styrene monomer inhibited?
TBC is 4-tert-butylcatechol, the polymerisation inhibitor carried in the monomer to stop styrene self-polymerising in storage and transit. The polymer grade we supply carries 10–30 ppm TBC, and polymer content on the batch certificate is 5 ppm max. TBC needs dissolved oxygen to work, so both inhibitor level and dissolved oxygen must be maintained.
What is the storage temperature for styrene monomer?
Store cool, below 25 °C, away from heat, sparks and oxidisers. Maintain inhibitor and dissolved oxygen. It is a flammable liquid and vapour — UN 2055, Class 3.
What purity and specification of styrene monomer do you supply?
Polymer grade, TBC-inhibited: purity 99.7 % m/m min, colour 10 APHA max, refractive index 1.5460 – 1.5470 @ 20 °C. Benzene, toluene, xylenes and high boils are nil, ethyl benzene 50 ppm max, polymer content 5 ppm max, low boils reported. Values are batch-verified against the certificate of analysis on receipt — the full table is in TDS SPC-TDS-MON-002, with the MSDS alongside it.
Who supplies styrene monomer in Chennai, and in what packaging?
We supply Styrene Monomer in bulk tanker and drums from Chennai across South India. The material is imported and supplied ex-import, batch tested on receipt at Ennore, Chennai. Order sizes depend on packaging and current stock — call or WhatsApp +91 86087 80096 for a quote.
