　　 Usage
　　 This product has a significant effect on improving the low-temperature resistance and anti-aging properties of agricultural films. It is a multifunctional, proton-inert, high-boiling solvent. It is particularly effective as a solvent in polymer synthesis, such as in the synthesis of polyphenylene sulfide and aromatic polyamides. It serves as a co-catalyst in the bulk polymerization of propylene. Adding this product to ethylene-propylene rubber can enhance elasticity and oil resistance.
　　 Specification of Hexamethylphosphoramide
　　 Hexamethylphosphoramide is a high-boiling, strongly polar organic solvent that is miscible with water and can even dissolve inorganic salts, hence it is known as a "universal solvent." It can dissolve polyvinyl chloride, polyphenylene sulfide, polyvinylidene chloride, polyacrylonitrile, polyester, polyether, polyvinyl alcohol, polyamide, polyurethane, nitrocellulose, etc. It is also used as an additive in ethylene-propylene rubber to improve elasticity and oil resistance. Store in a cool, well-ventilated warehouse away from fire and heat sources.
