Q1: What is the primary application segment for BASF C64 D 53 TPU Elastomer?
A: BASF C64 D 53 is a thermoplastic polyurethane elastomer specifically engineered for demanding extrusion and injection molding applications, with strong suitability in automotive interior components, technical profiles, and soft-touch overmolding where consistent melt stability and surface aesthetics are critical.
Q2: How does C64 D 53 differ from other TPU grades in terms of processing behavior?
A: C64 D 53 offers enhanced melt homogeneity and reduced viscosity sensitivity across typical processing temperatures, enabling smoother extrusion of thin-walled profiles and improved flow into complex mold geometries without excessive shear heating or degradation risk.
Q3: Is this grade suitable for applications requiring long-term UV exposure?
A: While C64 D 53 provides inherent hydrolytic stability and good thermal resistance, it is not inherently UV-stabilized. For outdoor or extended UV-exposed applications, post-compounding with appropriate light stabilizers (e.g., HALS) is recommended to maintain mechanical integrity and surface appearance over time.
Q4: Can C64 D 53 be co-extruded with common engineering thermoplastics?
A: Yes — C64 D 53 demonstrates good interfacial adhesion with several polyolefins and engineering plastics such as PP and ABS when processed under optimized temperature and shear conditions, making it well-suited for multi-layer co-extrusion and structural bonding applications.
