Quality Control

Our thermoplastic polyurethane polymers are manufactured under strict process controls to ensure batch-to-batch consistency and meet defined performance specifications. Quality is verified through a series of tests including intrinsic viscosity, melt flow index, hardness (Shore A/D), tensile strength, and elongation at break. Certificates of Analysis (COA) detailing key physical and mechanical properties are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the original packaging sealed until use to prevent moisture absorption, which can affect processing and final properties.
