PVC foamboards are white in colour. They are light weight, mostly matte but sometimes have a glossy finished surface.
They come in 4ftx8ft (1.2*2.4m) in size, ranging from 3mm to 20mm thicknesses.
They can be used for large format printing, general Signage making, architectural models, picture frames, etc.
The ABS and Corex sheets also come in the same size and can be used for the same purposes.
