Q1: What are the key processing advantages of Merrell TPUH110 compared to conventional TPU grades?
A: Merrell TPUH110 offers enhanced melt flow and reduced viscosity at standard extrusion and injection molding temperatures, enabling smoother processing in thin-wall or complex geometries. Its balanced thermal stability supports consistent output without premature degradation during extended runs.
Q2: Is Merrell TPUH110 suitable for applications requiring high abrasion resistance and flexibility at low temperatures?
A: Yes — as a polyester-based thermoplastic polyurethane elastomer, TPUH110 delivers excellent resistance to wear, tearing, and dynamic flexing, while retaining elasticity down to approximately −30 °C. Performance in extreme cold depends on part design and service conditions.
Q3: Can Merrell TPUH110 be blended with other polymers, and what compatibility considerations apply?
A: TPUH110 shows good miscibility with certain polyesters and compatible thermoplastic elastomers when properly dried and processed. However, blending with non-polar resins (e.g., PP or PE) typically requires compatibilizers or functionalized additives to achieve stable morphology and mechanical performance.
Q4: What drying conditions are recommended prior to processing Merrell TPUH110?
A: To prevent hydrolysis and surface defects, TPUH110 should be dried at 80–90 °C for 3–4 hours using desiccant-assisted air. Resin moisture content should be maintained below 0.05% before melt processing.
