PC is a polycarbonate rod as the main component by co-extrusion technology CO-EXTRUSION made of a high quality rod. Because of its surface is covered with a layer of a high concentration of UV absorbers, except with anti-UV properties and maintain long-term weather outside, never fade. PC connectivity is available glue connecting rods, effective leak polycarbonate (PC) rod has good mechanical properties, impact resistance and weather resistance. Maintain the physical performance and stability in the range of -40 ℃ to + 120 ℃. Dimensionally stable when heated. Light weight, the weight of the PC board is equal to 1/2 the thickness of the glass, excellent electrical properties and dielectric properties, good light, 3mm transparent sheet is 87% light transmittance, high transparency, transparency, low turbidity Haze (Haze), light transmission rate of 93%, diameter size from the outside diameter Ф5-Ф800 etc.
