Baydur® 730 IBS

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. *These items are provided as general information only. They are approximate values and are not part of the product specifications.

Isocyanate Component -Component A (PMDI isocyanate blend) must be stored in tightly closed containers to prevent contamination with moisture and other foreign materials, which can adversely affect processing. It will react slowly with water to form polyureas and liberate 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 (polyether polyol system) is slightly hygroscopic and may absorb water. Containers must be kept tightly closed and protected from contamination with moisture and foreign materials. 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.
