This newer material is used in a wide variety of applications including packaging films, lenses, vials, displays, and medical devices.

"[1] These later materials using a single type of monomer are more properly named cyclic olefin polymers (COP).

High ultraviolet transmission is a hallmark of COC materials, with optimized grades the leading polymer alternatives to quartz glass in analytical and diagnostic applications.

Most often, due to cost, COC is used as a modifier in monolayer or multilayer film to provide properties not delivered by base resins such as polyethylene.

Another noted application which often relies on a high percentage of COC in the end product is pharmaceutical blister packaging.

[4] The high purity, moisture barrier, clarity, and sterilization compatibility of COC resins make them an excellent alternative to glass in a wide range of medical products.

COC has a very low-energy and nonreactive surface, which can extend shelf life and purity of medications such as insulin and other protein drugs in applications such as vials, syringes and cartridges.

[6] The low dielectric constant of COC, even at high frequency, has led to its use in certain antenna applications as well as capacitors requiring higher temperature resistance than polypropylene can provide.
