Q1: What are the key processing advantages of Merrell TPUH230 compared to conventional TPU grades?
A: Merrell TPUH230 offers enhanced melt stability and reduced viscosity at processing temperatures, enabling smoother extrusion and injection molding—particularly beneficial for thin-walled or highly detailed parts. Its balanced hardness and flow characteristics support consistent throughput with lower torque demand on equipment.
Q2: Is Merrell TPUH230 suitable for applications requiring resistance to hydrolysis and long-term thermal aging?
A: Yes—TPUH230 is formulated with a polyester-based backbone modified for improved hydrolytic stability over standard polyester TPUs, and demonstrates robust retention of mechanical properties after extended exposure to elevated temperature and humidity, making it appropriate for demanding outdoor or under-hood applications.
Q3: Can Merrell TPUH230 be blended with other polymers, and what compatibility considerations apply?
A: TPUH230 exhibits good miscibility with certain engineering thermoplastics—including specific grades of PC, ABS, and polyolefins—when used as a compatibilizer or impact modifier. Successful blending requires careful attention to melt temperature windows, shear history, and interfacial adhesion; pilot-scale trials are recommended to confirm morphology and performance in the final compound.
Q4: What surface finish and adhesion characteristics can be expected when using Merrell TPUH230 in overmolding applications?
A: TPUH230 provides excellent substrate bonding to common rigid plastics such as PP, PS, and ABS without mandatory primers—especially when process parameters (e.g., mold temperature, melt temperature, and dwell time) are optimized. It typically yields a smooth, low-gloss surface with inherent tactile softness and resistance to fingerprint retention.
