Quality Control

Our Hydroxystyrene-Styrene is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Quality is verified through a suite of analytical techniques including HPLC, GPC, and NMR to confirm composition, molecular weight distribution, and purity. A Certificate of Analysis (COA) detailing specific lot results is provided with every shipment. We support customer audits and can provide material to meet the stringent requirements of advanced industrial 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 heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in the original packaging or opaque containers until use.
