Spray-on bed liner boasts bio-based polyurethane
Bio Tuff system sprays on 1/8-in.-thick polyurethane foam liner that protects beds, trailers, frames, and fenders. Replaces petroleum-based polyols, used to manufacture conventional bed liners, with SoyOyl, a soy-based polyol. Matches hardness and tensile strength and surpasses elongation performance of comparable petrochemical-based bed liners. SoyOyl costs less than petroleum polyol, needs less energy to produce, and because it derives from renewable soybean-plant resources, it reduces consumption of petroleum reserves.
