Bayfill NV 100 acoustic cavity-filling foam is a two-component polyurethane system designed to fill and acoustically seal cavities of automobile body shells. The Bayfill NV 100 acoustic cavity-filling foam system can be processed on both high- and low-pressure equipment. It is poured at a 1:1 ratio, providing excellent mix even on low-pressure equipment and an excellent shot-to-shot repeatability. Comparable low concentrations of residual MDI and low foam surface temperatures allow for safer dispense operations. As with any product, use of the Bayfill NV 100 acoustic cavity-filling 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 NV 100 acoustic cavity-filling foam system is supplied as two components. Component A is a modified polymeric diphenylmethane diisocyanate blend. Component B is a polyether polyol system.
