sPS

polymer

Syndiotactic polystyrene (sPS) is a high-performance engineering thermoplastic with a highly ordered, crystalline molecular structure that distinguishes it from conventional atactic polystyrene. Its superior thermal stability and rigidity make it suitable for demanding applications requiring sustained performance at elevated temperatures, such as automotive under-hood components, electrical connectors, and appliance housings where dimensional stability and creep resistance are critical.

Regulatory Screening

Environmental

Safety & Biocompatibility

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.
