Q1: What is the primary function of BASF C90A 15HPM in TPU formulations?
A: BASF C90A 15HPM is a high-performance processing aid designed to improve melt flow, reduce extrusion torque, and enhance surface finish in thermoplastic polyurethane (TPU) compounds—particularly during calendering, film casting, and profile extrusion.
Q2: Is C90A 15HPM compatible with all TPU chemistries (e.g., polyester-, polyether-, and polycaprolactone-based)?
A: Yes, C90A 15HPM demonstrates broad compatibility across major TPU families. It is especially effective in aromatic polyester TPUs commonly used for demanding mechanical and abrasion-resistant applications, but performance optimization may vary depending on base polymer polarity and molecular weight.
Q3: How does C90A 15HPM affect final TPU part properties such as tensile strength or elasticity?
A: When used at recommended dosage levels, C90A 15HPM typically maintains key mechanical properties—including tensile strength, elongation at break, and rebound resilience—while significantly improving processability. Minor reductions in modulus may occur at higher loadings, so formulation balancing is advised.
Q4: Can C90A 15HPM be used in applications requiring food contact or medical compliance?
A: C90A 15HPM is not pre-qualified for direct food-contact or medical device applications. Its use in regulated end-uses requires full formulation evaluation—including migration testing and regulatory review—by the compounder or end-user to confirm compliance with applicable regional requirements.
