Q1: What is the primary function of BASF C60 A 10WH in TPU formulations?
A: BASF C60 A 10WH is a hydrolysis-stabilizing additive specifically designed to enhance the long-term durability of thermoplastic polyurethane (TPU) elastomers exposed to humid or elevated-temperature conditions. It functions by scavenging acidic degradation products formed during hydrolytic cleavage of urethane bonds.
Q2: Is C60 A 10WH compatible with all common TPU chemistries (e.g., polyester-, polyether-, and polycaprolactone-based)?
A: Yes, C60 A 10WH demonstrates broad compatibility across major TPU base chemistries. It is particularly effective in polyester-based TPUs, which are most susceptible to hydrolysis, but also provides measurable stabilization benefits in polyether and polycaprolactone variants when processing or end-use conditions involve moisture exposure.
Q3: How is C60 A 10WH typically incorporated into TPU compounds?
A: It is commonly added during compounding—either as a masterbatch or directly in powder form—using standard melt-processing equipment such as twin-screw extruders. Good dispersion is achieved under typical TPU processing temperatures (170–220 °C), and no pre-drying of the additive is required prior to use.
Q4: Does C60 A 10WH affect the mechanical or optical properties of the final TPU product?
A: At recommended dosage levels, C60 A 10WH has minimal impact on tensile strength, elongation, hardness, or clarity. It is formulated to deliver stabilization without compromising key performance attributes—making it suitable for demanding applications such as transparent films, medical tubing, or high-gloss automotive trim.
