Highly consistent hydroxyl functionality and molecular weight distribution for reliable urethane reaction kinetics.
Low monol content and excellent color stability (APHA ≤ 30), supporting premium elastomer and coating aesthetics.
Optimized primary hydroxyl content for enhanced reactivity with isocyanates in fast-cure systems.
Excellent compatibility with aromatic and aliphatic isocyanates, as well as common chain extenders and fillers.
Manufactured under strict ISO 9001-certified process control to ensure batch-to-batch reproducibility.
High-performance thermoplastic polyurethane (TPU) for extrusion and injection molding.
Cast elastomers requiring high tensile strength, abrasion resistance, and dynamic resilience.
Polyurethane coatings and adhesives demanding rapid demold time and low-temperature flexibility.
Microporous shoe soles and automotive interior components with stringent VOC and odor specifications.
Specialty sealants and potting compounds requiring hydrolytic stability and long-term elasticity.
