Baydur 665 IBS is a black-pigmented, rigid 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 polymeric diphenylmethane diisocyanate (PMDI), and Component B is a formulated polyol system containing no CFC- or HCFC-blowing additives. Note: Component B should be agitated thoroughly prior to delivery of drum contents to day tank due to possible pigment settling.
The Baydur 665 IBS system is used for general-purpose applications that require injection times longer than 10 seconds. The applications, typically found in the construction, furniture, and transportation markets, take advantage of the material's strength as well as its excellent surface finish, large part capability, and good flowability. As with any product, use of the Baydur 665 IBS system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
