Plastic Machining with COC/COP Plastic

Welcome. In this video, we're going to talk about COC and COP machined parts.
COC stands for cyclic olefin copolymers, and COP stands for cyclic olefin polymers (COP), but to make it easy, we refer to these materials as COC and COP.

At Controlled Fluidics, these are two of our top 10 most popular materials. They're commonly used in medical devices, diagnostic applications, research components, and the microfluidics industry, but that's certainly not the whole list.

Why are these materials so popular? Well, it's due to their durability and biocompatibility. They also offer heat and chemical resistance.

Beyond that, one of the key benefits of COC and COP is that they share optical properties with glass. They offer exceptional transparency and very low birefringence. That means that when light rays pass through this material they aren't split in two. There's no double refraction.

COC and COP materials also have a very high Abbe number. That's great because the higher the number, the better the visual quality. These materials have low dispersion and reduced chromatic aberration.

COC and COP also boast high resistance to heat, and unlike polycarbonate or acrylics, they're not sensitive to moisture. That's one of the reasons people choose these materials over others.

One drawback of COC/COP is that stock shapes are sometimes not available. However, when you work with us at Controlled Fluidics, we leverage our connections with suppliers to get you the materials you need for your project. When that's not possible, we help you find the best alternatives.

This only covers the basics. Learn more about COC/COP Plastics on our materials page.
