Quality Control

Our Phenol, 4-Ethenyl-, Polymer With Ethenylbenzene is manufactured under strict quality management systems. Each batch undergoes comprehensive analysis to ensure consistency in molecular weight distribution, composition, and purity, meeting the stringent requirements of the electronics and specialty chemical industries. Certificates of Analysis (COA) detailing key parameters such as monomer ratio, glass transition temperature (Tg), and residual solvent content are provided with every shipment.

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 oxidizing agents. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption which may affect performance.
