Optical material COC480R, Japanese Rieon high-purity medical packaging

Description :

　　Optical material COC480R, Japanese Rieon high-purity medical packaging

　　Characteristics of COC:

　　(1) Low density, about 10% lower than PMMA (polymethyl methacrylate) and PC (polycarbonate), which is beneficial for lightweight products;

　　(2) The saturated water absorption rate is low, and the water absorption rate of COC is much lower than that of PMMA. It 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;

　　(4) The glass transition temperature of highly heat-resistant transparent resin reaches 140-170 ℃, which is the heat resistance index of amorphous polymers;

　　(5) Easy injection molding;

　　(6) Excellent mechanical properties, with higher tensile strength and elastic modulus than PC;

　　(7) Excellent reproducibility results in high product quality;

　　(8) Low dielectric constant, especially good high-frequency performance, making it a material with dielectric properties in thermoplastic materials;

　　(9) Good scratch resistance, COC pencil hardness is similar to PMMA, scratch resistance is an important performance indicator of optical materials;

　　(10) The side chains of COC molecules have polar groups, which have good adhesion to inorganic and organic materials and are easy to seal;

　　Applications: Materials for medical optical components, light guide plates for lenses and LCD displays, optical films and other optical fields, packaging materials, medical testing instruments, electronic devices, etc. The main uses of amorphous polyolefin optical transparent plastic are: protective film for optical lenses, optical announcers, polygon mirrors, angle plates, DVD disc substrates, large displays, backlight light guide plates, small display front light guide plates, optical semiconductors, optical fibers, and analytical chemistry instruments.
