CREAMELT® COC is a transparent filament made from Cyclic Olefin Copolymer (COC). COC is typically used for optical applications, medical devices or pharmaceutical packaging. It offers many benefits over other polymers: biocompatibility, transparency, very low water absorption, good barrier properties, excellent resistance to acids and alkalis as well as many sterilization processes. It has very good melt processability and can be printed on standard FFF 3D printer. The amorphous polymer doesn’t warp and has an excellent print performance. Printed parts are translucent and have excellent mechanical properties.
