Q1: What is the primary function of BASF 1175 A 10W in TPU formulations?
A: BASF 1175 A 10W is a liquid polymeric processing aid designed to improve melt flow, reduce extrusion pressure, and enhance surface finish in thermoplastic polyurethane (TPU) compounds—particularly during high-speed extrusion or injection molding.
Q2: Is BASF 1175 A 10W compatible with all TPU chemistries (e.g., polyester-, polyether-, and polycaprolactone-based)?
A: It demonstrates broad compatibility across major TPU families, including polyester- and polyether-based systems. Performance may vary depending on TPU polarity and molecular weight; compatibility testing under actual processing conditions is recommended for new formulations.
Q3: How does BASF 1175 A 10W affect mechanical properties of the final TPU part?
A: When used at typical dosage levels, it generally maintains key mechanical performance—including tensile strength, elongation, and abrasion resistance—while significantly improving processability. Excessive addition may reduce hardness or modulus; optimal dosage depends on formulation requirements and target processing window.
Q4: Can BASF 1175 A 10W be used in applications requiring food contact or skin contact?
A: BASF 1175 A 10W is not pre-approved for direct food contact or prolonged skin contact applications. Its suitability for such uses must be evaluated case-by-case, considering regulatory status of the full formulation, migration behavior, and applicable regional compliance requirements.
