These properties make it popular in a variety of industrial and consumer applications.
• Optics: Production of lenses, light guides, and other optical components requiring high transparency and low birefringence.
• Medical industry: Manufacturing of syringes, vials, and lab containers due to biocompatibility and sterilization resistance.
• Packaging: Used in premium packaging for pharmaceuticals and cosmetics, thanks to excellent moisture and gas barrier properties.
• Electronics: Manufacturing of components like capacitors and insulators due to low dielectric constant and good insulation properties.
• D printing: COC is used in 3D printing where high precision, transparency, and dimensional stability are required.
• Exceptional transparency: COC offers high clarity comparable to glass, making it ideal for optical applications.
• Low birefringence: The material has low birefringence, meaning it minimally alters light polarization – critical in optics.
• High heat resistance: COC maintains its mechanical properties at high temperatures, allowing use in demanding environments.
• Low moisture absorption: The material resists moisture, ensuring dimensional and property stability even in humid conditions.
• Good chemical resistance: COC is resistant to many chemicals, making it suitable for various industrial uses.
• Higher cost: Production of COC is more expensive compared to some other thermoplastics, which may limit its use in cost
• sensitive applications.
• Scratch sensitivity: The material can be prone to scratching, potentially affecting its aesthetic appeal and functionality.
• Limited solvent resistance: COC may be sensitive to certain organic solvents, which should be considered when selecting materials.
