Poly(3-chlorostyrene)

polymer

Poly(3-chlorostyrene) is a halogenated polystyrene variant in which chlorine atoms are substituted at the 3-position of the benzene ring along the polymer backbone. This engineering plastic is primarily investigated for applications requiring enhanced flame resistance, chemical resistance, and dimensional stability compared to unmodified polystyrene, making it relevant in sectors where thermal or chemical durability is critical. The material is used or considered for electrical enclosures, chemical-resistant housings, and flame-retardant consumer products, though it remains less common than other halogenated polymers like polychlorinated polystyrene or brominated alternatives.

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
