2-pyrrolidone

NMP is a key solvent in lithium-ion battery production, accounting for 3–6% of manufacturing costs and affecting coating efficiency and product consistency. With the growing energy storage and power battery markets, demand for high-purity NMP is increasing.

At East Chemical, we maintain strict quality control from raw materials to final distillation, ensuring moisture content below industry standards and purity over 99.9%. Our reliable supply chain and expertise help battery manufacturers lower production costs, improve coating performance, and boost overall yield, providing real value and reliability to our partners.

NMP is a nitrogen heterocyclic compound, which is a non-toxic, high boiling point,

strong polarity, low viscosity, low corrosiveness, high solubility, low volatility, good stability and easy recovery.

Our internationally certified NMP products are low in moisture and impurities, high in purity, and chemically stable, making them suitable for demanding industries such as pharmaceuticals and electronics. Consistent batches ensure process consistency, reducing production fluctuations while mitigating quality risks and regulatory compliance pressures.
