Q1: What is the primary application domain for Merquinsa 48-60/3?
A: Merquinsa 48-60/3 is a thermoplastic polyurethane elastomer specifically engineered for high-performance extrusion and injection molding applications, commonly used in flexible tubing, technical profiles, and soft-touch overmolding where resilience, abrasion resistance, and consistent melt processability are required.
Q2: Is this grade suitable for food-contact or medical-grade processing?
A: Merquinsa 48-60/3 is formulated without plasticizers or heavy-metal catalysts and is compatible with common food-contact and medical-grade compounding practices; however, final regulatory compliance depends on the full formulation, processing conditions, and end-use validation by the compounder or device manufacturer.
Q3: How does Merquinsa 48-60/3 differ from standard aromatic TPU grades?
A: Unlike conventional aromatic TPUs, Merquinsa 48-60/3 features an aliphatic backbone, delivering superior UV stability and long-term color retention—making it especially suitable for outdoor applications or transparent/colored parts where yellowing must be minimized.
Q4: What drying and processing conditions are recommended?
A: Prior to processing, Merquinsa 48-60/3 should be dried at 70–80 °C for 2–4 hours to achieve a moisture content below 0.05%. Typical melt processing temperatures range between 170 °C and 210 °C, depending on equipment and part geometry.
