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.
