Quality Control

Our liquid crystal polymer is manufactured under a strict quality management system. Each batch is tested against key performance parameters including intrinsic viscosity, thermal transition temperatures (DSC), and mechanical properties to ensure consistent lot-to-lot performance for critical molding applications. Comprehensive Certificates of Analysis (COA) documenting purity, melt viscosity, and thermal stability are available upon request.

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 polymer is hygroscopic (moisture-sensitive); keep the original packaging sealed until use to prevent moisture absorption, which can affect processing characteristics.
