Q1: What is the primary function of BASF KONZ 530/2 in TPU formulations?
A: KONZ 530/2 is a specialized processing aid designed to improve melt flow and reduce extrusion pressure during TPU compounding and shaping. It helps enhance surface finish, minimize die build-up, and support consistent throughput in extrusion and injection molding operations.
Q2: Is KONZ 530/2 compatible with all common TPU types (e.g., polyester-, polyether-, and polycaprolactone-based)?
A: Yes — KONZ 530/2 has demonstrated broad compatibility across major TPU chemistries. It is particularly effective in medium-to-high viscosity grades and shows stable dispersion without compromising mechanical properties or long-term elastomeric performance.
Q3: How should KONZ 530/2 be incorporated into TPU processing?
A: It is typically added directly to the TPU resin prior to extrusion or injection molding — either via gravimetric feeding, tumble blending, or masterbatch dilution. Pre-drying of the additive is not required, but uniform distribution is recommended to ensure optimal effect.
Q4: Does KONZ 530/2 affect the final TPU’s physical properties such as tensile strength or elasticity?
A: When used within the recommended dosage range, KONZ 530/2 does not significantly alter key mechanical or dynamic properties. Minor reductions in modulus may occur at higher loadings, but overall elastomeric behavior, resilience, and elongation remain well preserved.
Q5: Can KONZ 530/2 be used in applications requiring food contact or medical-grade compliance?
A: KONZ 530/2 is not pre-qualified for food-contact or medical applications. Its suitability for such uses depends on full formulation evaluation, regulatory review, and end-product testing under applicable regional requirements. Customers must conduct their own due diligence and validation.
