Aliphatic polyester diol with low viscosity for enhanced processability in reactive systems.
Excellent hydrolytic stability due to saturated backbone and absence of ester groups prone to degradation.
Consistent molecular weight distribution ensuring reproducible performance in polyurethane elastomers and coatings.
Low volatility and high thermal stability, supporting safe handling and elevated processing temperatures.
Compatible with isocyanates (e.g., HDI, IPDI) and chain extenders for tailored mechanical property profiles.
Castable polyurethane elastomers for industrial rollers, mining screens, and wear-resistant linings.
High-performance thermoplastic polyurethane (TPU) formulations requiring resilience and abrasion resistance.
Two-component polyurethane coatings for automotive trim, architectural substrates, and protective finishes.
Adhesives and sealants demanding flexibility, adhesion to diverse substrates, and environmental durability.
Reaction injection molding (RIM) and structural foam components in transportation and appliance sectors.
