Q1: What is the primary function of BASF KONZ 518/1 in TPU formulations?
A: KONZ 518/1 is a specialized processing aid designed to improve melt flow and reduce extrusion torque in thermoplastic polyurethane (TPU) compounds, particularly during high-output compounding or profile extrusion.
Q2: Is KONZ 518/1 compatible with all major TPU chemistries (e.g., polyester-, polyether-, and polycaprolactone-based TPUs)?
A: Yes, KONZ 518/1 demonstrates broad compatibility across common TPU base resins. Performance may vary depending on molecular weight, hardness, and polarity—so formulation-specific evaluation is recommended before full-scale implementation.
Q3: How does KONZ 518/1 affect the mechanical properties of the final TPU product?
A: When used within the recommended dosage range, KONZ 518/1 typically has minimal impact on tensile strength, elongation, or hardness. It is formulated to support processability without compromising key performance attributes of the base TPU.
Q4: Can KONZ 518/1 be added directly during extrusion, or is pre-blending required?
A: KONZ 518/1 can be introduced either via gravimetric feeding alongside the TPU resin or as a masterbatch—both methods are widely used. Direct addition during twin-screw extrusion is common and effective when feed stability and dispersion are optimized.
