Q1: What is the primary application segment for BASF B90A 15 TPU Elastomer?
A: BASF B90A 15 is a thermoplastic polyurethane elastomer specifically developed for demanding extrusion and injection molding applications, with strong suitability in automotive interior components, technical profiles, and flexible overmolding where balanced processability, surface quality, and mechanical resilience are required.
Q2: How does B90A 15 differ from standard aromatic TPU grades in terms of processing behavior?
A: B90A 15 features optimized melt flow and reduced thermal sensitivity compared to conventional aromatic TPUs, enabling stable extrusion at lower barrel temperatures and improved dimensional consistency during high-speed molding—particularly beneficial for thin-walled or complex geometries.
Q3: Is B90A 15 suitable for applications requiring resistance to common automotive fluids?
A: Yes, B90A 15 exhibits good resistance to oils, greases, and non-polar solvents typically encountered in under-hood and interior automotive environments, though long-term exposure to aggressive brake fluids or concentrated acids should be evaluated case-by-case through application-specific testing.
Q4: Can B90A 15 be processed on standard thermoplastic equipment without modification?
A: Yes, B90A 15 is fully compatible with conventional injection molding machines and single-screw extruders designed for thermoplastics. Pre-drying is recommended to maintain optimal melt stability and surface finish, and standard screw geometries used for engineering thermoplastics generally deliver satisfactory results.
