Q1: What is the primary function of Lubrizol TPU TT-2065D-B20 in thermoplastic polyurethane (TPU) formulations?
A: Lubrizol TPU TT-2065D-B20 is a specialized internal lubricant designed to enhance melt flow and processability of TPU during extrusion, injection molding, and calendering—without compromising mechanical integrity or surface aesthetics.
Q2: Is TT-2065D-B20 compatible with aromatic and aliphatic TPU grades?
A: Yes, TT-2065D-B20 demonstrates broad compatibility across both aromatic and aliphatic TPU chemistries, supporting consistent performance in diverse formulation systems including polyester-, polyether-, and polycaprolactone-based TPUs.
Q3: How does TT-2065D-B20 affect surface properties such as gloss and coefficient of friction?
A: It delivers balanced surface modification—reducing coefficient of friction for improved part ejection and handling while maintaining high surface gloss and minimizing bloom or haze under typical processing conditions.
Q4: Can TT-2065D-B20 be used in food-contact or medical-grade TPU applications?
A: While TT-2065D-B20 is formulated for high-purity performance, its suitability for regulated applications depends on final formulation validation and regulatory review by the end-user—Lubrizol recommends conducting full compliance testing per intended use and regional requirements.
