Abstract
A composition of a compounded PVC substrate that is suitable as an extrudate in very wide extruders. The composition is for use as a coating on scrim in the manufacture of billboards, wherein the composition does not yellow or burn, even in extruders having a die 215 inches wide (5,486 mm) with a 1.5 to 2.0 mm lip opening average. The composition has excellent printability, weather resistance and a price point that is low enough to meet competition. The composition has minimal quantities of lubricants and other processing aids, and utilizes a PVC suspension resin having high porosity. The invention enables the fabrication of printable billboard sheeting that is seamless.
