Quality Control

Our Oxirane,2,2'-[(3,3',5,5'-Tetramethyl[1,1'-Biphenyl]-4,4'-Diyl)Bis(Oxymethylene)] Bis-,Homopolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent epoxy equivalent weight (EEW), viscosity, and thermal properties critical for your formulations. Comprehensive Certificates of Analysis (COA) detailing purity, color, and key functional parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent premature polymerization or viscosity changes. Keep away from strong acids, bases, and oxidizing agents.
