COC particles, also known as cyclic Olefin Copolymer particles, are high-performance thermoplastic engineering plastics. COC has excellent optical properties, high transparency, low birefringence, as well as good heat resistance and chemical corrosion resistance. COC particles are formed by self polymerization of cyclic olefin monomers or copolymerization with other olefins, and their unique molecular structure endows the material with characteristics such as low water absorption, high strength, and low dielectric loss.
