Q1: What is the primary function of Lubrizol TPU D12T95 in thermoplastic polyurethane (TPU) formulations?
A: Lubrizol TPU D12T95 is a high-performance processing aid and surface modifier designed to enhance melt flow, reduce extrusion pressure, and improve surface finish in TPU compounds—particularly during extrusion, injection molding, and calendering processes.
Q2: Is Lubrizol TPU D12T95 compatible with all major TPU chemistries (e.g., polyester-based and polyether-based TPUs)?
A: Yes, it demonstrates broad compatibility across common TPU base resins, including both polyester- and polyether-type systems. Compatibility should be verified under actual processing conditions due to variations in molecular weight, hardness, and additive packages.
Q3: How does Lubrizol TPU D12T95 affect the mechanical properties of finished TPU parts?
A: When used at recommended dosage levels, it typically maintains key mechanical properties such as tensile strength, elongation, and tear resistance. Minor reductions in modulus may occur at higher loadings, so optimization for each application is advised.
Q4: Can Lubrizol TPU D12T95 help reduce die buildup or melt fracture during high-output extrusion?
A: Yes—its lubricating action at the polymer–metal interface helps minimize die lip buildup and suppresses melt fracture, especially in demanding applications like thin-gauge film or profile extrusion.
Q5: What is the typical dosage range for Lubrizol TPU D12T95 in TPU processing applications?
A: It is generally effective at low concentrations, typically ranging from 0.1% to 2% by weight relative to the base TPU resin, depending on equipment type, throughput rate, and desired surface or rheological outcome.
