Q1: What is Lubrizol TPU TT-1069D primarily used for?
A: Lubrizol TPU TT-1069D is a thermoplastic polyurethane-based additive designed to enhance melt processability, surface finish, and low-temperature flexibility in TPU compounds—particularly in extrusion and injection molding applications for automotive interior trim, industrial hoses, and soft-touch overmolding.
Q2: Is TT-1069D compatible with other thermoplastic elastomers besides TPU?
A: While optimized for TPU systems, TT-1069D demonstrates good compatibility with certain polyester- and polyether-based TPUs. Compatibility with non-TPU elastomers (e.g., TPE-S or TPO) should be evaluated case-by-case through laboratory-scale blending and rheological testing.
Q3: How does TT-1069D affect the mechanical properties of finished TPU parts?
A: At typical use levels, TT-1069D improves melt flow without significantly compromising tensile strength or elongation at break. Some formulations may show slight reductions in modulus or hardness, which are generally acceptable when balanced against enhanced process stability and surface aesthetics.
Q4: What is the recommended dosage range for TT-1069D in TPU formulations?
A: Dosage depends on the base resin, processing conditions, and target performance. It is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—and should be optimized through application-specific trials.
