Q1: What is the primary function of Lubrizol TPU EG-72D in thermoplastic polyurethane (TPU) formulations?
A: Lubrizol TPU EG-72D is a high-performance processing aid and surface modifier designed to improve melt flow, reduce extrusion torque, and enhance surface gloss and slip characteristics in TPU compounds—without compromising mechanical integrity or thermal stability.
Q2: Is Lubrizol TPU EG-72D compatible with all major TPU chemistries (e.g., polyester-, polyether-, and polycaprolactone-based TPUs)?
A: Yes, EG-72D demonstrates broad compatibility across common TPU backbone types. It is particularly effective in polyester- and polyether-based systems, where it helps mitigate melt adhesion and die buildup during high-speed extrusion or injection molding.
Q3: How should Lubrizol TPU EG-72D be incorporated into a TPU compound?
A: It is typically added directly to the base TPU resin via dry blending prior to extrusion or compounded using standard twin-screw extrusion techniques. No pre-drying is required, and it disperses readily under typical melt-processing conditions.
Q4: Does Lubrizol TPU EG-72D affect the final product’s regulatory compliance for food-contact or medical applications?
A: EG-72D is not intended for direct food-contact or implantable medical use. Its suitability for regulated end uses depends on full formulation evaluation and compliance testing by the compounder or end-user—Lubrizol does not certify final articles for specific regulatory frameworks.
