Description

Propanol, Oxybis-, Polymer With 1,1-Methylenebisisocyanatobenzene is a specialized polyurethane prepolymer or resin intermediate formed from the reaction of an oxybispropanol derivative with methylene diphenyl diisocyanate (MDI). This compound matters as a high-performance building block, offering tailored reactivity and physical properties for formulating advanced polymeric materials. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as by producers of specialty composites and binders.

Application

• Polyurethane Coatings: Serves as a key resin component for high-durability industrial, protective, and decorative coatings.
• Adhesives & Sealants: Used in formulating structural adhesives, potting compounds, and flexible or rigid sealants with strong bonding properties.
• Elastomers: Acts as a prepolymer in the production of castable polyurethane elastomers for wheels, rollers, and industrial parts.
• Composite Binders: Employed as a matrix resin in fiber-reinforced plastics (FRP) and other composite materials.
• Encapsulation Resins: Used for electrical encapsulation and potting due to its potential for good dielectric properties and chemical resistance.
• Flexible Foams: Can be utilized as a component in the formulation of specialized flexible polyurethane foams.
