There are other manufacturers which produce colored HDPE sheet however it is very important how this is done. It is relatively straight-forward to add color and ultraviolet protection (UV). However we have learned through research and real-time outdoor testing, in Florida and Arizona, that this is not enough. Therefore our coloring system includes an engineered UV Pigmentation Process (UPP*) which allows the color to resist fading! This is very important as now your HDPE sheet will retain its color and look vibrant in the application!
