Q1: What is Lubrizol TPU 2540 primarily used for?
A: Lubrizol TPU 2540 is a thermoplastic polyurethane-based processing aid designed to improve melt flow, reduce extrusion pressure, and enhance surface finish in rigid PVC formulations—particularly in profiles, pipes, and sheets.
Q2: Is Lubrizol TPU 2540 compatible with common PVC stabilizer systems?
A: Yes, it demonstrates broad compatibility with calcium–zinc, lead-based, and organotin stabilizers typically used in rigid PVC applications, without adversely affecting thermal stability or long-term color retention.
Q3: How does Lubrizol TPU 2540 affect the mechanical properties of finished PVC products?
A: When used at recommended dosage levels, it maintains or slightly improves impact strength and tensile properties while significantly enhancing processability—without compromising rigidity or dimensional stability.
Q4: Can Lubrizol TPU 2540 be used in food-contact or potable water applications?
A: Lubrizol TPU 2540 is formulated for use in PVC compounds intended for regulated applications; however, final compliance depends on the full formulation, processing conditions, and applicable regional regulatory assessments. It is not pre-approved as a standalone food-contact substance.
