Q1: What is the primary processing method recommended for Merrell TPUH130?
A: Merrell TPUH130 is specifically formulated for melt-processing techniques including extrusion, injection molding, and blow molding. It exhibits excellent melt stability and low viscosity at standard processing temperatures, enabling consistent flow and good surface finish in finished parts.
Q2: How does Merrell TPUH130 compare to conventional polyester-based TPUs in terms of hydrolytic stability?
A: As a polyether-based TPU elastomer, Merrell TPUH130 offers significantly enhanced resistance to hydrolysis compared to polyester-type TPUs—especially under warm, humid conditions or prolonged water exposure. This makes it well-suited for applications requiring long-term durability in challenging environmental conditions.
Q3: Is Merrell TPUH130 suitable for applications requiring flexibility at low temperatures?
A: Yes, Merrell TPUH130 maintains good low-temperature flexibility and impact resistance due to its polyether soft segment structure. It typically remains pliable and resilient down to approximately −30 °C, supporting performance in cold-climate or refrigerated-use applications.
Q4: Can Merrell TPUH130 be blended with other thermoplastics or elastomers?
A: Merrell TPUH130 demonstrates reasonable compatibility with certain engineering thermoplastics such as polypropylene and some grades of polyethylene when used with appropriate compatibilizers. However, blending should be validated case-by-case through rheological and mechanical testing, as phase separation may occur with incompatible polymers.
