Q1: What is the primary function of BASF KONZ 134/F in TPU formulations?
A: BASF KONZ 134/F is a specialized processing aid and surface modifier designed to improve melt flow, reduce extrusion die buildup, and enhance surface gloss and slip characteristics in thermoplastic polyurethane (TPU) compounds.
Q2: Is KONZ 134/F compatible with all major TPU chemistries (e.g., polyester-, polyether-, and polycaprolactone-based)?
A: Yes, KONZ 134/F demonstrates broad compatibility across common TPU base resins, including aromatic and aliphatic variants. Performance optimization may vary depending on polymer polarity and molecular weight, and small-scale compatibility testing is recommended for critical applications.
Q3: How is KONZ 134/F typically incorporated into TPU production?
A: It is most commonly added during compounding—either via side-feeding or pre-blending—prior to extrusion. Due to its low volatility and thermal stability, it remains effective under standard TPU processing temperatures (typically up to 220 °C).
Q4: Does KONZ 134/F affect the mechanical properties of the final TPU product?
A: At recommended use levels, KONZ 134/F has minimal impact on tensile strength, elongation, or hardness. Its main influence is on processability and surface behavior—not bulk mechanical performance—making it suitable for applications where aesthetics and production efficiency are key.
