Product Series
COC
Overview
Cyclic olefin copolymer (COC) is obtained by copolymerization of norbornene and polyethylene under the action of metallocene catalyst
Amorphous copolymers with excellent transparency and moisture resistance, excellent water vapor barrier properties, chemical resistance and safety, ranging from medicines, pharmaceuticals, packaging, and electronic components with strict quality standards. The field plays a role.
It has optical performance comparable to PMMA and heat resistance higher than that of PC. It also has better dimensional stability than PMMA and PC. It is highly evaluated in the optical market. It also has the advantages of improving water vapor air tightness, increasing rigidity, heat resistance, and being able to give easy cutting properties, etc.
