Quality Control

Our Polysilane is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistency in molecular weight distribution, purity, and functional performance. Certificates of Analysis (COA) detailing key parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and moisture absorption. Recommended long-term storage temperature is 2-8°C. Keep away from heat, sparks, and open flames.
