High Optical Clarity

A hallmark of all Zeon Cyclo Olefin Polymer (COP) resins is the high transparency across a range of wavelengths (> 91% between 400 – 700 nm). Zeon's optical grade COP resins also feature low birefringence and other features tailored for optical applications.

Durability

The high mechanical stability of Zeon’s COP provides improved durability compared to other clear plastics. Medical grade ZEONEX^® and ZEONOR^® COP resins feature high-impact strengths, even at cryogenic (-194°C) temperatures, and can withstand higher stress from viscous drug formulations and auto-injection devices.

Low Moisture Absorption

Inherently highly hydrophobic, Zeon’s COP resins resist moisture absorption and have very low water vapor transmission. This enables high-performing optical lenses without distortion under high humidity and moisture protection of sensitive pharmaceuticals.

Moldability

The high melt flow rate of Zeon's COP resins enables the creation of intricate, high-precision designs with exceptional moldability and flatness, meeting diverse manufacturing needs efficiently.

Production Capacity and Supply Chain Integrity

In mass production since 1990’s and globally adopted across Life Sciences, Optical, Consumer Electronics and Automotive Industries, Zeon's Cyclo Olefin Polymer (COP) has become the material of choice when quality matters and performance is critical. Zeon has met the growing demand for COP through numerous expansions of its manufacturing facilities and careful management of the supply chain.
