What kind of resin is AC resin (AC as raw material for the production of glasses lenses)?
Polymethyl methacrylate abbreviation code PMMA, commonly known as plexiglass, is by far the most transparent synthetic materials of the best quality, the price is more suitable varieties. PMMA resins are not prone to produce sharp fragments during fragmentation, and have advantages in optical properties:1, visible light: visible light transmittance is higher: PMMA is the most excellent polymer transparent material, visible light transmittance of 92%, higher than the transparency of glass.
AC is the abbreviation of acrylic ester Acrylate. The AC resin used here is made of polymethyl methacrylate.
Ultraviolet light: quartz can completely penetrate ultraviolet light, but the price is high. Ordinary glass can only penetrate 0.6% ultraviolet rays, but PMMA can pass through 73%. PMMA cannot filter out ultraviolet light (UV). UV light will penetrate the PMMA, and some manufacturers are coating on the PMMA surface to increase the effect and properties of UV filtering. On the other hand, PMMA has better stability in comparison with polycarbonate under UV irradiation.
Infrared: PMMA allows infrared rays less than 2800nm wavelengths to pass. The longer wavelength IR, which is less than 25000nm, is substantially blocked. There are special colored PMMA that allow specific wavelengths of IR to pass through while blocking visible light (for remote control or thermal stress, etc.).
