Description

Propylene Carbonate CAS NO 108-32-7 is a high-purity, aprotic cyclic carbonate solvent with excellent solvating power and a high dielectric constant. This versatile chemical is valued for its low toxicity, high boiling point, and biodegradability, making it a safer and more sustainable choice for demanding industrial formulations. It is an essential component for manufacturers in the lithium-ion battery, agrochemical, paint and coating, and pharmaceutical industries seeking efficient, high-performance solvents and reaction media.

Application

• Lithium-Ion Battery Electrolyte: A key high-purity solvent component in liquid and gel polymer electrolytes, prized for its high dielectric constant and stability at the anode interface.
• Agrochemical Formulations: Used as a polar, non-toxic solvent and carrier in pesticides, herbicides, and plant growth regulators, enhancing active ingredient solubility and penetration.
• Paint, Coating & Adhesive Stripper: An effective, low-VOC solvent for stripping paints, coatings, and adhesives, as well as a component in specialty coatings.
• Chemical Synthesis & Extraction: Serves as a green, polar aprotic reaction medium for polymerization, alkylation, and as an extractant for gases like CO2 and H2S.
• Personal Care & Cosmetic Products: Employed as a solvent and viscosity modifier in nail polish removers, cleansers, and other cosmetic formulations.
• Industrial Cleaning & Degreasing: An effective component in precision cleaning solutions for electronics and metal parts due to its solvating power and favorable evaporation profile.

Quality Control

Our Propylene Carbonate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. Production adheres to relevant ISO standards, and specific grades can be produced to meet battery-grade, industrial-grade, or high-purity requirements. Comprehensive testing is performed, and a Certificate of Analysis (COA) detailing purity, moisture content, and key impurities is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
