SD OPTRONICS Product advantages

High quality and stability, Affordable price
Excellent optical performance, with higher transparency, high quality stability, light incident uniformity.
SD OPTRONICS R&D improved old products issues on the market, impatient for ultraviolet radiation, almost no yellowish by long time usage, uneven coating of liquid crystal, poor weather resistance and other issues.
SD OPTRONICS Switchable Smart Film has a close adhesion, can be combined with a variety of laminating (PVB / EVA / EN), and maintain high yield rate.Note: different gluing method, the applications of the place are also limited, in line with the above gluing method to meet a large number of market demands. (Other brand – EVA only)
SD OPTRONICS Switchable Smart Film: Larger withstand voltage range (Special mode can be directly withstand 110V)Switchable Smart Film drive voltage: AC 65 ± 5 volts (50 / 60HZ)(Specific mode) feasible direct connection-AC 110 ± 5 volts (50 / 60HZ)
Development of damp environment application Dimming film: upgraded version of waterproof special treatment technology
In house made, self-produced, self-independent core technology, customized, one-stop service.
With a wide range of products: standard type, high transparent type, heat insulation type, color dimming film type, special treatment to strengthen the waterproof type, direct-pasted type, projection type, and so on a number of independent research and development products.
