Q1: What is the primary application domain for Merquinsa 45-40/15?
A: Merquinsa 45-40/15 is a thermoplastic polyurethane elastomer specifically engineered for flexible, high-clarity applications requiring excellent melt processability and good mechanical resilience — commonly used in extruded profiles, thin-walled tubing, and soft-touch overmolding layers.
Q2: How does Merquinsa 45-40/15 differ from standard aromatic TPU grades?
A: Unlike conventional aromatic TPUs, Merquinsa 45-40/15 features a tailored aliphatic/isophorone-based chemistry that delivers superior UV stability and reduced yellowing during processing and long-term service — making it suitable for applications where optical clarity and color retention are critical.
Q3: Can this grade be processed on standard thermoplastic equipment?
A: Yes — Merquinsa 45-40/15 is fully compatible with conventional extrusion, injection molding, and blow molding systems. It exhibits low melt viscosity and good thermal stability, allowing processing across a broad temperature window without significant degradation or gel formation.
Q4: Is drying required before processing?
A: Yes — like most TPUs, Merquinsa 45-40/15 is hygroscopic and must be thoroughly dried prior to processing. Recommended drying conditions are typically 70–80 °C for 2–4 hours using desiccant-assisted dryers to achieve moisture levels below 0.05% for optimal surface quality and mechanical performance.
