3. Applications and Functions
Tetrahydrofuran (THF) is a commonly used cyclic ether solvent with good solubility and volatility across various industries. Its main applications include, but are not limited to:
1. Polymer Materials: An important intermediate for producing poly(tetramethylene ether) glycol (PTMEG), also used in making elastomers, polyurethane, etc.
2. Solvent Uses: Suitable as a solvent for coatings, resins, inks, adhesives, and related systems.
3. Fine Chemical Intermediates: Can be used in pharmaceuticals, organic synthesis, and extraction processes.
4. Lithium Battery Materials: Used as a co-solvent in certain electrolyte systems.
4. Packaging Specifications
Common Packaging:
- 180kg/galvanized iron drum
- 20 tons/ISO tank container
Storage Conditions:
Store in a cool, dry, well-ventilated place, away from fire and oxidizing agents. Prevent polymerization reactions; add stabilizers (like BHT) to avoid property changes during long-term storage.
