Description

1,2-Propanediol, Polymer With 2,4-Diisocyanato-1-Methylbenzene And Methyloxirane is a specialized polyurethane polyol prepolymer derived from propylene glycol, toluene diisocyanate (TDI), and propylene oxide. This compound matters as a versatile building block for formulating high-performance polyurethane systems, offering tailored reactivity and physical properties. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing flexible and rigid foams.

Application

• Polyurethane Coatings: Serves as a key polyol component in high-durability industrial and protective coatings.
• Adhesives & Sealants: Used in formulating polyurethane-based adhesives and sealants with excellent bonding strength and flexibility.
• Elastomers: A precursor for manufacturing cast, thermoplastic, or millable polyurethane elastomers.
• Flexible & Rigid Foams: Acts as a polyol in the production of polyurethane foams for insulation, cushioning, and packaging.
• Resin Modification: Employed to modify the properties of other polymer resins, enhancing toughness or adhesion.
• Binder Systems: Used in composite materials and foundry binders.

Quality Control

Our polyurethane polyol prepolymers undergo rigorous quality testing to ensure batch-to-batch consistency and performance. Key parameters such as hydroxyl value, isocyanate content (NCO%), viscosity, and water content are strictly monitored. Certificates of Analysis (COA) documenting all specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance.
