| 备注说明 | Baydur 730 IBS is a 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 modified polymeric diphenylmethane diisocyanate (PMDI) prepolymer blend, and Component B is a formulated polyol system containing no CFC- or HCFC-blowing additives.The Baydur 730 IBS system was designed for general-purpose applications and is used in the construction, agricultural, consumer products, industrial and specialty automotive markets. The applications typically 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 730 IBS system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability. |
