Quality & Safety

Quality Assurance & Safety First

Every batch of polyether polyol is manufactured under strict quality management and supplied with comprehensive documentation.

⚠

Polyether polyols are hygroscopic materials that should be stored in sealed containers in dry, well-ventilated areas. Exposure to moisture can affect product quality and reactivity in polyurethane formulations. Our products are supplied with Certificates of Analysis (CoA) and Safety Data Sheets (SDS) for each batch. Always consult the Safety Data Sheet (SDS) before handling. For technical guidance on safe handling, storage, formulation optimization, or emergency response procedures, our global team is available around the clock.
