Applications

1. For Lithium Battery Electrolytes: Propylene carbonate (PC, CAS 108-32-7) is a high-purity cyclic carbonate solvent for lithium-ion battery and capacitor electrolytes, offering high dielectric constant, low toxicity and excellent thermal stability for reliable electrochemical performance.

2. For Acid Gas Removal And Natural Gas Treatment: PC is a proven physical solvent for removing carbon dioxide and hydrogen sulfide from natural gas, synthesis gas and process streams, supporting efficient decarbonization and gas purification in energy and chemical industries.

3. For Green Solvent Applications: With low toxicity, high boiling point and broad solvency, propylene carbonate serves as a green solvent in coatings, adhesives, paint strippers and cosmetics, helping formulators reduce hazardous solvent use.

4. For Chemical Synthesis And Intermediates: As a versatile polar aprotic solvent and intermediate, PC is used in organic synthesis and in the production of dimethyl carbonate and other carbonate derivatives for industrial applications.

5. For Plastics And Textile Processing: PC acts as a plasticizer, spinning solvent and dispersant for dyes and polymers, giving plastics, fiber and chemical manufacturers a multifunctional processing aid.

Quality Assurance

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
