Product description

Baydur 742 IBS is a semirigid polyurethane structural foam system used in the reaction injection molding (RIM) process.

Applications

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.

Storage

Isocyanate Component -Component A (PMDI isocyanate blend) will react with moisture and must be stored in tightly closed containers and protected from contamination with moisture and other foreign materials, which can adversely affect processing. It will react slowly with water to form ureas and carbon dioxide gas, which may cause sealed containers to expand and rupture. Storage temperatures should be maintained between 17° and 30°C (62° and 86°F). Polyol Component - Component B is hygroscopic and may absorb water. Containers should be kept in tightly closed and protected from contamination with moisture and foreign materials which can adversely affect processing. Storage should be maintained at ambient temperature. Note: Component B phase separates upon standing and must be mixed thoroughly via mechanical means prior to use.
