Q1: What is the primary application domain for Merquinsa 48-60/15?
A: Merquinsa 48-60/15 is a thermoplastic polyurethane (TPU) elastomer specifically engineered for demanding extrusion and calendering processes, commonly used in high-performance flexible films, coated textiles, and technical laminates requiring excellent melt stability and surface clarity.
Q2: How does Merquinsa 48-60/15 differ from standard aromatic TPUs in processing behavior?
A: Unlike many conventional aromatic TPUs, Merquinsa 48-60/15 offers enhanced thermal stability during melt processing—reducing yellowing and gel formation—while maintaining good die swell control and low melt viscosity, making it especially suitable for thin-gauge film production and multi-layer coextrusion.
Q3: Is Merquinsa 48-60/15 compatible with common plasticizers or polymer blends?
A: Yes—it demonstrates good compatibility with select non-migrating plasticizers and is frequently blended with other thermoplastic polymers such as PVC and certain polyesters to modify flexibility, adhesion, or surface properties; however, compatibility should always be verified experimentally for each specific formulation.
Q4: What are the recommended drying conditions prior to processing?
A: To ensure optimal melt quality and mechanical performance, drying at 70–80 °C for 3–4 hours under dehumidified conditions is generally recommended—though actual requirements may vary depending on ambient humidity, material history, and equipment configuration.
