Poly(4-chlorostyrene)

polymer

Poly(4-chlorostyrene) is a halogenated aromatic polymer derived from the substitution of a chlorine atom on the styrene monomer backbone, creating a thermoplastic with enhanced rigidity and chemical resistance compared to unmodified polystyrene. The material is used primarily in applications requiring improved solvent resistance, flame retardancy, and dimensional stability, such as electrical components, chemical-resistant coatings, and specialized industrial housings. Its chlorine substitution increases stiffness and thermal stability relative to standard polystyrene, making it valuable in demanding environments where chemical exposure or elevated temperatures are concerns, though its use is less widespread than commodity polymers due to cost and processing considerations.

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.
