As an accredited Diol factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Diol is packaged in a 1-liter amber glass bottle, sealed with a tamper-evident cap, and clearly labeled with safety instructions. |
| Shipping | Diol should be shipped in tightly sealed containers, clearly labeled with appropriate hazard identification. Store and transport it away from incompatible substances, in a cool, dry, well-ventilated area. Follow all relevant local, national, and international regulations for chemical transport to prevent leaks, spills, or exposure during transit. |
| Storage | Diols should be stored in a cool, dry, and well-ventilated area, away from sources of ignition, heat, and incompatible substances like strong oxidizers. Containers must be tightly sealed to prevent moisture absorption and contamination. Use properly labeled, chemical-resistant containers made of glass or compatible plastics. Always follow recommended safety practices and local regulations for safe chemical storage. |
Our facility produces diol in accordance with rigorous standards, supplying major industrial sectors with essential intermediates for downstream synthesis. The following application scenarios detail specific compliance protocols, formulation guidelines, integration points, and output products adopted by leading manufacturers worldwide.
Polyester resin producers use diol as a primary glycol component in the transesterification stage for thermosetting formulations. Technical teams adjust the glycol ratio to modulate curing rate, crosslink density, and ultimate mechanical properties required in various coatings and glass fiber reinforced resins.
