Q1: What is the primary application domain for BASF 1154 D 50U TPU Elastomer?
A: BASF 1154 D 50U is a thermoplastic polyurethane elastomer specifically engineered for extrusion and injection molding of high-performance flexible components, including technical hoses, protective sheathing, and dynamic sealing profiles where resilience, abrasion resistance, and low-temperature flexibility are critical.
Q2: How does 1154 D 50U differ from standard TPU grades in terms of processing behavior?
A: This grade features optimized melt flow characteristics for consistent extrusion and improved dimensional stability during cooling, with reduced die swell compared to conventional 50 Shore A TPUs—making it especially suitable for precision-profile applications requiring tight tolerances.
Q3: Is BASF 1154 D 50U compatible with common engineering thermoplastics for co-extrusion or overmolding?
A: Yes—it demonstrates good interfacial adhesion with polyamide (PA6, PA12) and polypropylene (PP) when processed under controlled temperature and residence time conditions, though compatibility testing under end-use conditions is recommended to verify bond strength and long-term performance.
Q4: What are the key storage and handling recommendations to maintain material integrity?
A: Store in original sealed packaging at temperatures below 30 °C and relative humidity below 50 % to prevent moisture absorption; pre-drying at 70–80 °C for 2–4 hours prior to processing is strongly advised to avoid surface defects and ensure optimal mechanical properties.
