Q1: What is the primary polymer architecture and typical hardness range of Merrell TPUH310?
A: Merrell TPUH310 is an aliphatic thermoplastic polyurethane elastomer based on polyester chemistry, offering excellent mechanical resilience and clarity. Its Shore A hardness typically falls within the medium-soft to medium range, making it suitable for flexible yet durable applications.
Q2: Is Merrell TPUH310 suitable for extrusion and injection molding processes?
A: Yes — Merrell TPUH310 is specifically engineered for standard thermoplastic processing methods including melt extrusion, injection molding, and calendering. It exhibits good melt stability and low viscosity at processing temperatures, supporting consistent part formation and surface finish.
Q3: How does Merrell TPUH310 perform under UV exposure and outdoor weathering conditions?
A: As an aliphatic TPU, Merrell TPUH310 demonstrates inherently superior UV resistance compared to aromatic grades. It maintains color stability and mechanical integrity during prolonged outdoor exposure, though long-term performance may be further enhanced with appropriate stabilizer packages.
Q4: Can Merrell TPUH310 be blended or compounded with other polymers?
A: Merrell TPUH310 shows good compatibility with certain engineering thermoplastics and elastomers — particularly other polyester-based TPUs and selected polyesters — enabling tailored property profiles. Compatibility should always be verified experimentally for each intended blend system.
