Glass-Like Clarity With Medical-Grade Performance
Cyclic olefin copolymer (COC) is a high-purity thermoplastic polyolefin known for its excellent moisture barrier, optical transparency, and superior impact strength.
Often used in medical and diagnostic devices because of its ultra low extractables, COC is a reliable material for high-precision, sterile environments where performance and purity are critical. COC is the most UV transparent thermoplastic on the market today, ideal for microwell reactor plates.
Trusted in Medical & Diagnostic Devices
COC is used where clarity, sterility, and moisture control are essential.

Frequently Asked Questions
Yes! Cyclic olefin copolymer is an excellent alternative to glass in many applications. It offers glass-like transparency with the added benefits of being lightweight, shatter-resistant, and easier to process. Its high impact strength reduces the risk of breakage, making it ideal for medical and laboratory environments where safety and durability are critical.
Absolutely. COC’s outstanding moisture barrier properties help preserve drug potency by minimizing water vapor transmission. It also maintains dimensional stability and chemical resistance, which are essential in drug delivery formats such as pre-filled syringes, blister packs, and microfluidic devices. Its inert nature supports compatibility with sensitive formulations.
Yes. At PolySource, we offer cyclic olefin copolymer resins that meet key regulatory standards such as FDA Drug Master File (DMF), USP Class VI, and ISO 10993. Our team provides hands-on support to help you select the right grade, document compliance requirements, and ensure your COC application aligns with all relevant industry and safety regulations.
