Q1: What is the primary function of Lubrizol TPU TT-1065D in thermoplastic polyurethane (TPU) formulations?
A: Lubrizol TPU TT-1065D is a high-performance processing aid and surface modifier designed to improve melt flow, reduce extrusion pressure, and enhance surface finish in TPU compounds—particularly during extrusion and injection molding processes.
Q2: Is TT-1065D compatible with all common TPU chemistries (e.g., polyester- and polyether-based TPUs)?
A: Yes, TT-1065D demonstrates broad compatibility across major TPU families, including aromatic and aliphatic polyester- and polyether-based grades. Compatibility should always be confirmed through small-scale formulation trials under intended processing conditions.
Q3: How does TT-1065D affect the mechanical properties of the final TPU product?
A: When used at recommended dosage levels, TT-1065D typically maintains key mechanical properties—including tensile strength, elongation, and tear resistance—while significantly improving processability. Minor reductions in modulus may occur at higher loadings, so optimization is advised for performance-critical applications.
Q4: Can TT-1065D be used in applications requiring regulatory compliance for food contact or medical devices?
A: TT-1065D is not pre-approved for food-contact or medical applications. Customers intending such use must conduct full regulatory evaluation—including extractables/leachables testing and toxicological assessment—as part of their own compliance program.
