Q1: What is the primary functional role of BASF S60AW in TPU formulations?
A: BASF S60AW is a polymeric processing aid designed to improve melt flow and reduce extrusion torque during TPU compounding and shaping. It enhances surface finish, reduces die buildup, and supports stable high-speed processing without compromising mechanical performance.
Q2: Is S60AW compatible with all major TPU chemistries (e.g., polyester- and polyether-based TPUs)?
A: Yes, S60AW demonstrates broad compatibility across aromatic and aliphatic polyester- and polyether-based TPUs. Its polymeric structure minimizes phase separation and avoids adverse effects on clarity, thermal stability, or long-term hydrolytic resistance when properly dispersed.
Q3: How does S60AW affect the mechanical properties of finished TPU parts?
A: At typical use levels, S60AW has minimal impact on tensile strength, elongation at break, or hardness. It may slightly reduce modulus at higher loadings, but this is generally offset by improved process consistency and part uniformity—especially in thin-walled or complex geometries.
Q4: Can S60AW be used in applications requiring food contact or skin-safe products?
A: S60AW is not intended for direct food contact or medical device applications. While it is non-toxic and commonly used in consumer-facing TPU articles (e.g., footwear, sporting goods), regulatory compliance must be verified case-by-case based on final formulation, processing conditions, and applicable regional requirements.
