Q1: What are the key processing advantages of BASF B90A 11 compared to conventional TPU grades?
A: BASF B90A 11 is specifically engineered for enhanced melt stability and reduced viscosity at processing temperatures, enabling smoother extrusion and injection molding—particularly beneficial for thin-walled or highly detailed parts. Its optimized thermal profile supports shorter cycle times and improved surface finish without sacrificing mechanical resilience.
Q2: Is B90A 11 suitable for applications requiring resistance to hydrolysis and low-temperature flexibility?
A: Yes—B90A 11 is an aliphatic polyester-based TPU with inherently good hydrolytic stability and retains excellent elasticity down to -30 °C. It is well-suited for outdoor or humid-environment applications where long-term performance under moisture exposure and thermal cycling is critical.
Q3: Can B90A 11 be co-extruded or overmolded with other thermoplastics?
A: B90A 11 demonstrates good adhesion to common engineering thermoplastics such as PP, ABS, and PC when processed under appropriate temperature and surface-energy conditions. Successful bonding typically requires controlled melt temperature windows and may benefit from surface pre-treatment or compatible tie-layer formulations.
Q4: How does B90A 11 perform in terms of UV resistance and color stability?
A: As an aliphatic TPU, B90A 11 offers superior UV resistance and minimal yellowing compared to aromatic TPUs. It maintains color fidelity and mechanical integrity during extended outdoor exposure, making it a preferred choice for transparent or light-colored exterior components.
