COC/COP

COC and COP offer many advantages over traditional amorphous plastics used in fluidic manifolds (such as acrylic, polycarbonate, and Ultem). COC and COP retain their properties to near glass temperature, and they are suitable for optical applications.

COC/COP AT A GLANCE

  • Best in class for transparency and light transmission
  • Low fluorescence
  • Low water absorption (hydrophobic)
  • Biocompatible
  • Superior chemical resistance
  • Very brittle and hard; does not scratch easily
  • Multiple temperature grades to 275°F working temperature
  • Suitable for optical applications
  • Excellent durability
  • Dimensionally stable
  • Low creep

More about COC & COP

COC and COP share glass’s exceptional optical properties while also offering exceptional transparency, low birefringence, a high Abbe number, and high heat resistance. Unlike polycarbonate and acrylics, COC and COP exhibit moisture insensitivity, giving them an advantage over competing materials. The materials’ biocompatibility makes COC/COP great options for microfluidics and life science, although the unavailability of stock shapes is a potential downside.
