N - methyl pyrrolidone NMP Strong Polarity Chemical Solvent for
Electronic Chemicals
Application
This product is an important chemical raw material, a polar solvent
with good selectivity and stability properties , low toxicity, high
boiling point , strong solvency, non-inflammable, has many
advantages, such as the biodegradation, reutilization, safety in
use and suitable for many kinds of prescription, etc. Its main
applications are as follows:
1. Concentrate the acetylene, Extracte the butadiene, isoprene,
aromatics, etc;
2. Lubricant refining;
3. Polymerizing solvent for the engineering plastics which are
difficult to dissolve ( such as the polyphenylene sulfide and the
polyimide ) and the aromatic fiber;
4. Electrical insulant, lithium ion battery;
5. High-class coating, printing ink, pigment;
6. Pesticide accessory ingredient;
7. Cleaners: deoil, defat, dewax, burnish, anti - rust and
depainting, etc;
8. The artifcial kidney function film liquid and the sea water
desalination film liquid.
Characteristics
Colorless and transparent liquid, with boiling point 202 oC and flash point 95 oC, can dissolvable in water and many solvents, such as
acetaldehyde, ether, acetone, etc.
