Application:
Hexamethylphosphoramide (HMPA) (CAS: 680-31-9) is soluble in polar and non-polar solvents. It is also miscible with the commonly used plasticizers such as dioctyl phthalate, dioctyl sebacate, and triphenyl phosphite in any proportion. Avoid contact with skin. Its containers should be tightly sealed to prevent leakage and water absorption to be deteriorated Hexamethylphosphoramide is the light stabilizer of the PVC, enabling an excellent anti-aging properties of outdoor products with excellent weather resistance, therefore being known as highly-efficient weathering agent of PVC. Addition of this product to the PVC film can significantly improve both the weather resistance and cold resistance as well as reducing the processing temperature by 10℃. 1. It can be used as the efficient anti-corrosion agent of PVC and other kinds of chlorine-containing resin products and coatings. 2. The product is the weathering solvent of polyvinyl chloride and excellent polar solvent, having a significant effect on the low temperature resistance and aging resistance of the agricultural film; it is a multi-functional high-boiling polar solvent that is aprotic. It can be used as the solvents of polymer synthesis with special effect on the synthesis of polyphenylene sulfide and aromatic polyamide and so on. This product, as the co-catalyst of propylene polymerization catalyst, when supplied to the ethylene propylene rubber, can improve the missile and oil resistance of the latter one. Hexamethylphosphoramide can also be used as a gas chromatographic fixative, ultraviolet inhibitor, rocket fuel additives for lowering the freezing point and chemical sterilizers. 3. It is effective non-proton solvent; as fixative of gas chromatography (highest usage temperature: 35°C with methanol as the solvent); used for separation and analysis of hydrocarbons; for separation of alkanes, alkenes and alkynes; accelerator of stereo-specific reaction; Ultraviolet inhibitor of PVC.
