EUROPLEX® Medical COC Film

Product Summary

EUROPLEX® Cyclic Olefin Copolymer (COC) films are high-performance films engineered for specialized medical, diagnostic, and microfluidic applications. Combining exceptional optical performance, chemical resistance, moisture barrier properties, and high purity, EUROPLEX COC films provide a reliable solution for applications where material performance and consistency are critical.

EUROPLEX COC films offer very low autofluorescence, excellent light transmission, and low birefringence, making select grades particularly well suited for optical analysis and diagnostic applications. Their high purity and compatibility with biological samples further support their use in lab-on-a-chip (LoC), microfluidic, and other medical applications.

Available EUROPLEX COC film grades include 0F304, 0F305, 0F308, and 0F309, offering a range of properties to meet specific application and processing requirements.
