Q1: What is the primary processing method for Merrell TPUH120?
A: Merrell TPUH120 is designed for melt-processing techniques including extrusion, injection molding, and calendering. It exhibits good thermal stability and melt homogeneity under standard thermoplastic elastomer processing conditions.
Q2: Is Merrell TPUH120 suitable for applications requiring flexibility and abrasion resistance?
A: Yes — as a thermoplastic polyurethane elastomer, TPUH120 offers excellent elasticity, tear strength, and surface durability, making it well-suited for dynamic components such as footwear uppers, protective films, and flexible industrial hoses.
Q3: How does Merrell TPUH120 compare to conventional polyester- or polyether-based TPUs in terms of hydrolytic stability?
A: Merrell TPUH120 is formulated with enhanced resistance to hydrolysis compared to standard polyester TPUs, particularly under warm, humid conditions. Its molecular architecture helps maintain mechanical integrity during prolonged exposure to moisture without requiring additional stabilizers in most standard applications.
Q4: Can Merrell TPUH120 be blended with other polymers?
A: Yes — TPUH120 demonstrates compatibility with several engineering thermoplastics, including certain grades of ABS, PC, and PP, enabling tailored compound formulations for improved impact performance or processability. Compatibility should be verified experimentally for each intended blend system.
