Quality Control

Our Poly(Dimethylsilane) is manufactured under controlled conditions to ensure batch-to-batch consistency. Quality is verified through analytical techniques including Gel Permeation Chromatography (GPC) for molecular weight distribution and spectroscopic methods for structural confirmation. A Certificate of Analysis (COA) detailing purity, viscosity, and other critical parameters is provided with each shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C to maintain stability and prevent degradation. Keep away from heat, sparks, and open flames.
