Bayfill ST 120 is a two-component polyurethane foam system designed to fill cavities of automobile body shells. It has energy absorption capabilities as well as high modulus characteristics. The Bayfill ST 120 foam system can be processed on both high- and low-pressure equipment. It is poured close to a 1:1 ratio, providing excellent mix even on low-pressure equipment, and an excellent shot-to-shot repeatability. As with any product, use of the Bayfill ST 120 foam system in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability. The Bayfill ST 120 foam system is supplied as two components. Component A is a modified polymeric diphenylmethane diisocyanate blend. Component B is a polyether polyol system.
