Product Description

Product Description

Cyclic Olefin Copolymer (COC) is a high-performance polymer prepared by metallocene catalyzed copolymerization of ethylene and a cycloolefin monomer such as norbornene or its derivatives. This material has excellent optical transparency, low birefringence, chemical resistance and good heat resistance, while maintaining good processability. Because of these excellent properties, COCs are widely used in products that require high transparency, such as optical lenses, packaging materials (such as vials), display components, and medical devices.

Product Usage

Cyclic Olefin Copolymer (COC) is a high-performance polymer with excellent optical transparency, low birefringence, chemical resistance and good heat resistance. COC is mainly used in the following areas:
1. Optical lenses: COC's excellent optical properties make it ideal for high-end optical lenses. Packaging materials: Especially in pharmaceutical and food packaging, COC's high transparency and chemical resistance ensure product safety and shelf life.
2. Medical devices: COCs have a wide range of applications in the medical field, such as syringes, catheters, and other single-use medical devices.
3. Display components: The low birefringence of COC makes it suitable for the protective film and substrate of the display.
4. Electronics industry: Especially in radome materials related to 5G technology, COC is favored due to its stable dielectric properties.
