MAKROLON® GP PRISMATIC P12

MAKROLON GP Prismatic P12 polycarbonate sheet is a proprietary pattern with UV stability and UL 94 V2 rating for gauges greater than .125" in thickness.

The prismatic pattern enhances the light transmission (86% ASTM D1003) and offers superb diffusion and hiding power, along with a refractive index of 1.586 (ASTM D542). MAKROLON GP Prismatic P12 polycarbonate sheet is warranted for five years against breakage.

Applications:

MAKROLON GP Prismatic P12 polycarbonate sheet is used wherever impact resistance, light diffusion, and low flammability are required.
