🔍 Product Overview
Our polyether polyol for polyurethane elastomers is a highly reactive, low-odor, low-acid value polyol designed specifically for the production of thermoset polyurethane elastomers. These elastomers offer excellent mechanical strength, abrasion resistance, hydrolysis resistance, and long-term flexibility.
The polyol is optimized for use in both hot-cast and cold-cure elastomer systems, and is fully compatible with MDI (Methylene Diphenyl Diisocyanate) and TDI (Toluene Diisocyanate). It is widely used in industrial wheels, rollers, seals, gaskets, and mining equipment linings.
✅ Key Features & Benefits
Excellent Mechanical Properties – Enables high tensile strength, elongation, and tear resistance
Controlled Reactivity – Supports consistent and efficient curing in elastomer formulations
Hydrolysis Resistance – Suitable for applications in humid, wet, or chemically aggressive environments
Good Flowability – Optimized for accurate mold filling and processing stability
Formulation Flexibility – Compatible with chain extenders, plasticizers, and other additives
Customizable Grades – Available in multiple hydroxyl values and molecular weights for tailored needs
