Cyclo-Olefin Polymer (COP, also called Cyclic Olefin Polymer) is a type of amorphous polymer used in a wide variety of applications including medical devices and pharmaceutical packaging, optics and displays and electronics. COP is formed by ring-opening metathesis polymerization (ROMP) of cyclic olefin monomers such as Norbornene, followed by partial or total hydrogenation. Modification of the monomer structure results in polymers with a range of glass transition temperatures, stiffness and viscosities.

Cyclo Olefin Copolymer (COC) is produced via an alternative process involving copolymerization with ethylene. Cyclo-Olefin Polymer (COP) formed by ring-opening metathesis polymerization (ROMP) offers greater transparency and mechanical stability and its surface is more amenable to plasma treatment for optimizing cell growth.

Yes, medical-grade resins ZEONEX^® 690R, ZEONEX^® 790R, ZEONEX^® 5000 and ZEONOR^® 1020R, made of Cyclo Olefin Polymer, have been assessed for compliance with USP Class IV and <661.1>, ISO 10993, in addition to JP and EU standards. This makes these grades ideal for syringes, vials, microplates, diagnostic consumables, and other life science applications. FDA Drug Master File information is available upon request. 

ZEONEX^® and ZEONOR^® are not suitable for use inside the human body.

ZEONEX^® and ZEONOR^® is up to 2.5 times lighter than glass, easing handling and reducing transportation costs. The higher impact strength of ZEONEX^® and ZEONOR^®, over a wide range of temperatures including cryogenic storage, ensures that breakage during storage, handling and transportation is minimized.

ZEONEX^® offers excellent optical properties, lighter weight and easier processing making it ideal for creating optical parts for digital cameras lens and mobile phone lenses.

Medical-grade resins ZEONEX^® 690R, ZEONEX^® 790R, ZEONEX^® 5000 and ZEONOR^® 1020R can be sterilized using EtO, gamma and electron beam sterilization and vaporized hydrogen peroxide. Due to their higher glass transition temperatures, ZEONEX^® 690R and ZEONEX^® 790R can also be steam sterilized.

Low autofluorescence in COP is crucial for applications in medical diagnostics, life sciences, and optical devices where precise fluorescence detection is required. ZEONOR^®’s minimal background fluorescence ensures clearer signal readings in assays, imaging, and microfluidic devices, reducing interference and improving accuracy in sensitive optical and biological analyses. 

Conventional polymers, (PS, COC, PC), typically exhibit an order of magnitude larger fluorescence ratio than ZEONOR® Cyclo Olefin Polymer. The low autofluorescence properties of ZEONOR^® make it an ideal substrate for fluorescence-based applications.

ZeonorFilm^® is a high-performance optical film made from ZEONOR^® Cyclo Olefin Polymer (COP).

ZeonorFilm^® provides unmatched optical uniformity, low haze, high transparency, superior low water absorption and excellent moisture barrier, high heat resistance, low dielectric constant and low outgassing.

ZeonorFilm^® offers high transmittance, low birefringence and low haze, which enables high resolution, sharp images on LCD/OLED without any distortion. 

The HWP (half wave plate) and QWP (quarter wave plate) of ZeonorFilm^® are made with Zeon’s proprietary extrusion and stretching process. The precision production process enables ZeonorFilm^® to offer functions like anti-reflection on OLED, sunglass readable on LCD/OLED and viewing angle improvement on LCD.

ZeonorFilm^® is made from ZEONOR^® Cyclo Olefin Polymer (COP), which offers unique properties including glass-like transparency, low haze, low water absorption and low outgassing. 

With Zeon’s proprietary extrusion and stretching technology, ZeonorFilm^® offers excellent thickness uniformity, stable optical performance and a wide range of retardation values.

ZeonorFilm^® is available in a variety of grades. The glass transition temperature (Tg) of the raw material ranges from approximately 120°C to 170°C.

ZeonorFilm^® has a low dielectric constant and low loss tangent, which minimizes transmission loss in transmitting electric signals. The high glass transition temperature (Tg ~ 170°C) of ZF16 film is an excellent option for flexible copper plated film substrate.

TIMs are materials used to enhance heat transfer between two surfaces. They fill the microscopic gaps between surfaces to improve thermal conductivity and efficiency.

VB200, Zeon's TIM offers you 38 W/m K excellent thermal conductivity in the vertical direction by using Zeon's unique manufacturing method that vertically arranges the fillers. In addition, the use of special polymers ensures long-term reliability.

Zeon’s TIMs are designed to solve the thermal management issues associated with the miniaturization and high integration of electronic devices. For this reason, Zeon’s TIMs are suitable for use in integrated circuit chips, (IC chips), such as CPUs and GPUs, and applications that require withstanding harsh environments.

CPME is a totally new hydrophobic ether solvent which was established out of Zeon’s unique synthetic technology and C5 raw materials. Unlike other common ether solvents, CPME has unique properties and is widely applicable as a replacement for Tetrahydrofuran (THF), Methyl Tert-Butyl Ether (MTBE), Dioxane and other existing ether solvents.

CPME has wide applicability as a reaction, extraction and synthesis solvent. Its high purity contributes to polymerization and the extraction of specific components. CPME is easily separated and recovered from water, reducing the amount of waste liquid and wastewater.

CPME provides you with a wide range of applications such as the following. 

• Reactions
• Extractions
• Crystallizations
• Polymerizations
• Coating solvents for resins

Cyclopentanone is a high boiling point solvent with a five-membered ring structure. It offers high compatibility and excels in extraction because of its good solubility for a range of compounds.
