Q1: What is the primary application domain for Merquinsa 17076/16?
A: Merquinsa 17076/16 is a thermoplastic polyurethane elastomer specifically engineered for demanding extrusion and injection molding applications, with strong suitability in technical films, flexible tubing, and high-performance seals where resilience, abrasion resistance, and low-temperature flexibility are critical.
Q2: Is this grade suitable for contact with food or potable water?
A: Merquinsa 17076/16 is not pre-certified for food-contact or potable water applications. Customers requiring regulatory compliance must conduct full formulation-level testing and validation according to applicable regional requirements, as final approval depends on processing conditions, additives, and end-use configuration.
Q3: How does Merquinsa 17076/16 compare to standard polyester-based TPUs in terms of hydrolytic stability?
A: As a polyester-type TPU, Merquinsa 17076/16 offers good mechanical performance but exhibits lower inherent hydrolytic resistance compared to polyether-based TPUs. For long-term use in humid or aqueous environments, stabilization—such as incorporation of hydrolysis inhibitors or careful drying prior to processing—is recommended.
Q4: What drying conditions are recommended before processing?
A: To ensure optimal melt stability and mechanical properties, Merquinsa 17076/16 should be dried thoroughly prior to processing—typically at 80–90 °C for 3–4 hours in a dehumidifying dryer. Residual moisture levels should be maintained below 0.05% to prevent degradation during melt processing.
