Q1: What is the primary function of Lubrizol TPU TT-2075D-B20 in thermoplastic polyurethane (TPU) formulations?
A: Lubrizol TPU TT-2075D-B20 is a high-performance processing aid and melt flow modifier specifically designed to enhance extrudability, reduce melt viscosity, and improve surface finish in TPU compounds—without compromising mechanical properties or thermal stability.
Q2: Is TT-2075D-B20 compatible with aromatic and aliphatic TPU grades?
A: Yes, TT-2075D-B20 demonstrates broad compatibility across both aromatic and aliphatic TPU base resins, supporting consistent performance in diverse processing conditions including extrusion, injection molding, and calendering.
Q3: How should TT-2075D-B20 be incorporated into TPU formulations?
A: It is typically introduced during compounding—either pre-blended with TPU pellets or added directly to the extruder feed throat. Uniform dispersion is readily achieved under standard melt processing conditions; no pre-drying is required beyond standard TPU handling practices.
Q4: Does TT-2075D-B20 affect the clarity or color stability of transparent TPU products?
A: When used at recommended dosage levels, TT-2075D-B20 maintains excellent optical clarity and shows minimal impact on yellowness index (YI) during processing and aging—making it suitable for demanding transparent and light-colored TPU applications.
