Baydur 742 IBS is a semirigid polyurethane structural foam system used in the reaction injection molding (RIM) process. This system incorporates a specially engineered interactive blowing system (IBS) and is supplied as two reactive liquid components. Component A is a modified polymeric diphenylmethane diisocyanate (PMDI) prepolymer blend, and Component B is a formulated polyol system containing no CFC- or HCFC-blowing additives. Baydur 742 IBS system is used in the consumer products market for applications requiring some protective cushioning characteristics. The system is typically molded at medium-to-high densities. As with any product, use of the Baydur 742 IBS system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability. |
