Q1: What is the primary function of BASF C60 A 10W in TPU formulations?
A: BASF C60 A 10W is a hydrolysis-stabilizing additive specifically designed to enhance the long-term durability of thermoplastic polyurethane (TPU) elastomers exposed to moisture and elevated temperatures. It functions by scavenging acidic degradation products formed during hydrolytic cleavage of urethane bonds.
Q2: Is C60 A 10W compatible with all major TPU chemistries (e.g., polyester-, polyether-, and polycaprolactone-based TPUs)?
A: Yes, C60 A 10W demonstrates broad compatibility across common TPU base resins, including polyester-, polyether-, and polycaprolactone-type systems. Its liquid form and low volatility support uniform dispersion during compounding without adversely affecting melt rheology or final mechanical properties.
Q3: How is C60 A 10W typically incorporated into TPU processing?
A: It is commonly added directly to the TPU melt during extrusion compounding or injection molding—either via side-feeding or inline metering. Due to its low viscosity and thermal stability up to typical TPU processing temperatures, it integrates efficiently without requiring pre-dilution or special handling.
Q4: Does C60 A 10W affect the color or clarity of transparent or light-colored TPU parts?
A: When used at recommended dosage levels, C60 A 10W has minimal impact on optical properties. It is formulated to be non-yellowing and does not introduce haze or discoloration in clear or pastel-grade TPUs under standard processing and aging conditions.
