Outstanding abrasion resistance, oil/solvent resistance, high resilience, high-pressure resistance, and mechanical properties.
Applications: Conveyor belts, tubing, seals, cables, compound modification, automotive parts, casters, footwear materials, overmolding, and other industries.
TPU (Thermoplastic Polyurethane Elastomer) is widely used in automotive, sports equipment, and industrial manufacturing sectors due to its exceptional abrasion resistance, which exceeds that of natural rubber by more than five times.
