Q1: What is the primary application domain for Merquinsa 45-60/25 TPU Elastomer?
A: Merquinsa 45-60/25 is a thermoplastic polyurethane elastomer specifically engineered for demanding extrusion and injection molding applications, including flexible tubing, technical profiles, and high-resilience automotive interior components where consistent melt stability and excellent abrasion resistance are required.
Q2: How does this grade differ from standard aromatic TPU elastomers in terms of processing behavior?
A: Unlike conventional aromatic TPUs, Merquinsa 45-60/25 features a tailored molecular architecture that delivers enhanced thermal stability during melt processing—reducing yellowing and viscosity drift at elevated barrel temperatures—while maintaining good flow characteristics for thin-walled or complex geometries.
Q3: Is Merquinsa 45-60/25 suitable for applications requiring long-term UV exposure?
A: This grade is not inherently UV-stabilized; prolonged direct UV exposure may lead to surface discoloration and gradual reduction in mechanical performance. For outdoor or UV-intensive applications, integration of appropriate HALS-based stabilizers and/or protective topcoats is strongly recommended.
Q4: Can it be blended with other polymers such as PVC or polyolefins?
A: Merquinsa 45-60/25 exhibits limited compatibility with non-polar polymers like polyolefins due to polarity mismatch; however, it can be compatibilized in controlled blends with certain plasticized PVC systems—typically requiring careful optimization of shear history and additive selection to ensure phase dispersion and interfacial adhesion.
