APL5514ML Mitsui COC Optical Grade Special Material in Stock from Japan
The molecular structure of COC contains hard non-polar cyclic branches, which is completely different from typical polyolefins. It is precisely because this molecular structure endows COC with high transparency, low birefringence, low moisture absorption, and low shrinkage of amorphous polymers, while also endowing COC with high heat resistance, high hardness, and high modulus. Its main application competitors are polycarbonate (PC) and polymethyl methacrylate (PMMA).
(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.
