Trade information

General introduction

Zeonex 690R Cyclic Olefin Polymer (COP) is medical grade low bireringence, high moisture barrier, Glass transition temperature 136°C, melt flow 17.

▸	Low birefringence medical grade
▸	Strong chemical and solvent stability
▸	Highly clarity, light transmitting 92%

Typical application

●	Optical field: Mobile phone/camera lenses, projector lenses (high transmittance + low chromatic aberration)
●	Medical field: Testing instrument tanks, pharmaceutical packaging (low hygroscopicity to prevent pollution)
●	Electronic field: High-frequency substrates, insulating components (low dielectric loss)

Why Zeonex 690R

●	Low hygroscopicity (0.1%) ensures dimensional stability in high humidity environments and avoids deformation of optical components

●	The balance between dielectric performance and stability, also the mechanical strength and process adaptability while maintaining low Dk/Df, making it the preferred material for high-frequency scenarios such as 5G base stations, automotive radars, and satellite communications
