Product Description
Solar Grade Coextruded Polycarbonate sheet for signs combines the impact strength of polycarbonate sheet with a proprietary UV- resistant cap layer that provides long-term protection against weathering. Providing long-lasting clarity over a wide range of environments, Polycarbonate offers extended service life and reduced life-cycle material costs. It is an excellent candidate for all types of thermoformed or flat signs, whether screen printed, painted, or decorated with vinyl graphics.
