Cyclic olefin copolymer - Wikipedia
Cyclic olefin copolymer (COC) is an amorphous polymer made by several polymer manufacturers. COC is a relatively new class of polymers as compared to commodities such as polypropylene and polyethylene. This newer material is used in a wide variety of applications including packaging films, lenses, vials, displays, and medical devices.
Cyclo-Olefin Copolymer - an overview | ScienceDirect Topics
Cyclo olefin copolymers are amorphous, transparent copolymers of cyclo olefins and linear olefins. They exhibit a combination of high transparency, excellent impact resistance, and improved shatter resistance compared to glass, and superior moisture barrier properties.
Cyclic Olefin - an overview | ScienceDirect Topics
Cyclic Olefin Copolymer (COC), with the trade name of Topas, is another high-temperature alternative to acrylic. Generally, it is a lower-cost alternative to COP. Particularly favorable is the high flowability (good injection moldability) of these thermoplastics.
