| Baydur 641 IBS is a rigid polyurethane structural foam system used in the reaction injection molding (RIM) process. This system is supplied as two reactive liquid components and is typically used with a blowing paste purchased separately. Component A is a polymeric diphenylmethane diisocyanate (PMDI). Component B is a formulated polyol system containing no CFC- or HCFC-blowing additives. The blowing paste is Baydur PU-1731. |
