Tuffak® R is made from recycled polycarbonate sheet and is significantly less expensive than standard Tuffak® sheets. Tuffak® R does contain tiny black specs throughout the material, due to it being recycled, but still makes for an ideal material in machine guarding and factory windows. Virtually unbreakable, Tuffak® R sheet is up to 300-times stronger than single-strength glass, and significantly tougher than other transparent sheet materials of equal thickness. It’s unlikely that Tuffak® R sheet will break, shatter or chip when bombarded with thrown missiles such as rocks, bricks or bottles. Nor is it likely that this material will break when hammered, twisted or bent.
