Quality Control

Our Poly-p-Phenylene Terephthalamide is produced under stringent quality management systems to ensure batch-to-batch consistency and performance. Quality is verified through a comprehensive suite of tests including intrinsic viscosity, thermal analysis (TGA/DSC), tensile strength, and elemental analysis. Certificates of Analysis (COA) detailing all specifications are provided with each shipment. We adhere to relevant industry standards and can support compliance requirements for defense and aerospace applications.

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). Keep away from strong acids, strong bases, and sources of excessive heat or ignition. The material is generally stable under recommended conditions but should be kept dry to prevent any potential hydrolysis over extended periods.
