Cyclic Olefin Copolymer
Characteristics (1) Low density, about 10% lower than PMMA (polymethyl methacrylate) and PC (polycarbonate), which is beneficial for product lightweighting; (2) The saturation water absorption rate is small, and the COC water absorption rate is much lower than PMMA, which will not cause a decrease in physical properties due to water absorption and almost does not absorb water; (3) Due to the presence of monomers with low polarity and anisotropy, it is an amorphous transparent material with a low birefringence index; (4) The glass transition temperature of transparent resin with high heat resistance can reach 140~170 ºC, which is the heat resistance index of amorphous polymers; (5) Easy to inject into shape; (6) Excellent mechanical properties, higher tensile strength and elastic modulus than PC; (7) Excellent reproducibility leads to high product quality; (8) Low dielectric constant, especially good high-frequency performance, makes it the material with the best dielectric properties for thermoplastic materials; (9) Good scratch resistance, COC pencil hardness is similar to PMMA, and scratch resistance is an important performance indicator of optical materials; (10) The side chains of COC molecules have polar groups, which have good adhesion with inorganic and organic materials and are easy to seal;

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.
