Tufnol Whale Plastic Sheet 20mm Thick for Wear Plates Rigid Grade

Tufnol Whale Plastic Sheet 20mm Thick Rigid SRBF Board

Some jobs need a material that simply refuses to bend, and a 20mm section is built for exactly that. Tufnol Whale Plastic Sheet 20mm Thick is an SRBF (Synthetic Resin Bonded Fabric), made from woven cotton cloth that is soaked in synthetic resin and pressed under high heat. The finished board is dense, flat and very stiff, yet far lighter than steel or aluminium. Its density is 1.36 g/cm³ for sheet and 1.35 g/cm³ for rod.

Because it is so thick, this sheet is well suited to bases, plates and blocks that take hard daily use. It saws, drills, turns and mills with ordinary workshop tools, leaving crisp edges and accurate dimensions. Wear, damp and heavy knocks do little to it, so parts made from this board keep their shape and last for years.
