High molecular weight uniformity with narrow polydispersity index (PDI), ensuring consistent reactivity and polymer performance.
Exceptional hydrolytic and thermal stability, enabling reliable processing in demanding industrial environments.
Low volatility and low color (APHA < 30), supporting high-clarity elastomer and coating formulations.
Precise end-group functionality (predominantly diol) for predictable urethane and polyester chain extension.
Consistent batch-to-batch quality backed by BASF’s global manufacturing standards and ISO-certified production.
Spandex (elastane) fibers for apparel and technical textiles requiring high elasticity and recovery.
Thermoplastic polyurethane (TPU) compounds used in automotive trim, footwear soles, and medical tubing.
High-performance polyurethane elastomers for industrial rollers, seals, and hydraulic hoses.
Castable polyurethane systems for mining screens, wear plates, and vibration-damping components.
Hybrid polyurethane-acrylic dispersions for durable, flexible coatings in architectural and industrial applications.
