Best Polycarbonate LED Diffuser Film

Product Description

UVTPC-DI Polycarbonate LED Diffuser Film helps to get soft and comfortable light as the high haze and light transmittance. Meantime, it offers excellent impact resistance, good flame retardant property, and dimensional stability in a large temperature from -40 °C to 120 °C.

Therefore, it is the right material for the LED lamp, LED sign, architectural lighting system, elevator lighting system, railcar lighting system, etc. Otherwise, Diffuser Film is also the right choice for industrial applications including the electron industry, machine vision system, and medical device inspection.
