Van Accessible stencil is made of Acrylonitrile Butadiene Styrene, more popularly known as the ABS plastic. The ABS stencils are 63 mils (1/16 inches) thick, ideal for parking lots and other outdoor applications. ABS is chosen for stencils because this type of plastic liquifies upon heating, instead of burning, which allows it to be readily injection-molded to any cutout or shape. Also, this plastic is easily recyclable, causing minimal harm to the environment.
