Q1: What are the key processing advantages of Merrell TPUH290 compared to conventional TPU grades?
A: Merrell TPUH290 offers enhanced melt flow and reduced viscosity during extrusion and injection molding, enabling smoother processing at lower temperatures and shorter cycle times. Its balanced hardness and elasticity also support excellent dimensional stability in thin-walled or complex geometries.
Q2: Is Merrell TPUH290 suitable for applications requiring hydrolysis resistance?
A: Yes — as an aliphatic polyester-based TPU elastomer, Merrell TPUH290 demonstrates significantly improved resistance to hydrolytic degradation compared to aromatic TPUs, especially under warm, humid conditions or prolonged water exposure.
Q3: Can Merrell TPUH290 be used in overmolding applications with common engineering thermoplastics?
A: Yes — it exhibits good interfacial adhesion when overmolded onto substrates such as ABS, PC, and polypropylene, provided appropriate mold temperature, melt temperature, and surface preparation are applied. Bond strength is formulation- and process-dependent.
Q4: How does Merrell TPUH290 perform in low-temperature flexibility applications?
A: It maintains excellent elasticity and impact resistance down to approximately −30 °C, making it well-suited for flexible components in cold-climate environments, including seals, gaskets, and dynamic parts subject to repeated flexing.
