· JVASP-129141· CoC

CoC (cyclic olefin copolymer) is an engineering thermoplastic that combines the rigidity and optical clarity of polystyrene with superior chemical resistance and low moisture absorption. It is widely used in precision optics, diagnostic devices, and packaging applications where dimensional stability and chemical inertness are critical, and is preferred over competing plastics like polycarbonate when transparency combined with barrier properties and low thermal expansion are essential.

Export Control

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.
