⭐ Product Overview
Our polyether and TDI-based polyurethane prepolymers are high-performance, moisture-curable, isocyanate-terminated polymers designed for elastomers, adhesives, coatings, and sealants (CASE) applications. Produced through the controlled reaction of polyether polyols and Toluene Diisocyanate (TDI), these prepolymers provide exceptional mechanical strength, flexibility, chemical resistance, and curing reliability.
They are widely used in hot cast PU elastomers, moisture-cured adhesives, PU coatings, and sealant formulations where consistent reactivity, long pot life, and high-performance curing are essential.
✅ Key Features & Benefits
Adjustable NCO Content – Tailored for specific application needs (elastomers, adhesives, sealants)
Excellent Processability – Optimized viscosity for pumping, mixing, and casting
Superior Mechanical Strength – Outstanding tensile, elongation, and abrasion resistance
Flexible Curing Conditions – Compatible with ambient and heat-assisted curing
Good Hydrolysis and Chemical Resistance – Suitable for outdoor and industrial environments
Low VOC Options – Eco-compliant, suitable for green polyurethane formulations
