Q1: What is the primary function of BASF 1190A 10 in TPU formulations?
A: BASF 1190A 10 is a specialized 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 and calendering processes.
Q2: Is BASF 1190A 10 compatible with all TPU chemistries (e.g., polyester-, polyether-, and polycaprolactone-based TPUs)?
A: Yes, BASF 1190A 10 demonstrates broad compatibility across major TPU families. It is especially effective in aromatic polyester- and polyether-based TPUs, where it helps mitigate melt fracture and improves dimensional stability during profile extrusion.
Q3: How should BASF 1190A 10 be incorporated into TPU processing?
A: It is typically added directly to the TPU resin prior to extrusion—either via gravimetric feeding or pre-blending. No pre-drying is required, and it remains stable under standard TPU processing temperatures (160–220 °C).
Q4: Does BASF 1190A 10 affect the mechanical or thermal properties of the final TPU product?
A: At recommended dosage levels, it has minimal impact on tensile strength, elongation, or Shore hardness. Long-term thermal aging performance and UV resistance of the base TPU are also preserved, as BASF 1190A 10 is non-volatile and chemically inert under normal service conditions.
