Applications：Propylene Carbonate (PC, CAS 108-32-7) is a high-performance polar solvent and fine chemical raw material, featuring low toxicity and strong chemical stability with wide applications across electronics, chemical engineering, polymer and other fields.

1. Electronics Field: It is a premium medium for high-energy batteries and capacitors. Battery-grade propylene carbonate produced by Hekesenyuan, featuring low water content and minimal impurities, serves as a key component of lithium-ion battery electrolytes. It can withstand harsh light, heat and chemical changes, protect graphite anodes, and is crucial for enhancing battery cycle life and stability. It is widely used in the manufacturing of batteries for new energy vehicles, smartphones and various electronic devices. Additionally, it is applied in capacitors to improve energy storage and charge-discharge performance.
2. Chemical Engineering Field: It is an efficient solvent for gas purification (desulfurization and decarbonization). With strong absorption capacity for carbon dioxide and hydrogen sulfide, it is extensively used in the purification of natural gas, liquefied petroleum gas, petroleum cracking gas and ammonia synthesis feed gas, helping reduce greenhouse gas emissions. Moreover, it is a core raw material for synthesizing dimethyl carbonate (DMC) through transesterification with methanol. It also acts as an extractant for olefins and aromatics, playing a role in chemical separation and purification processes.
3. Polymer & Adhesive Field: It serves as a solvent and plasticizer for polymers. Adding it to polyvinyl chloride (PVC) and other plastic products enhances flexibility and processability. It can also be used as a plasticizer for adhesives and sealants to improve flexibility and bonding performance. Furthermore, it is a curing accelerator for phenolic resins, accelerating the curing reaction rate. It can disperse pigments and fillers in water-soluble adhesives to ensure stable performance. When mixed with isocyanates in a specific ratio, it can be used as a high-strength wood adhesive to replace phenolic resins.
4. Textile Dyeing & Printing Field: It acts as an auxiliary in synthetic fiber production, helping optimize fiber processing performance. In the dyeing process, it serves as a fixing agent to improve the fastness of dyes on fibers, resulting in more durable and bright dyeing effects. It is also a spinning solvent and can disperse water-soluble dyes and pigments, ensuring the quality stability of textile dyeing and printing products.
5. Pharmaceutical & Daily Chemical Field: Chiral propylene carbonate is an important intermediate for the synthesis of various anticancer drugs. Ordinary propylene carbonate can be used as a drug carrier and solvent to enhance drug stability and solubility. In the daily chemical industry, it is used as an environmentally friendly solvent in cosmetic formulations such as perfumes and shampoos, and can also play a thickening and texture-stabilizing role, meeting the mildness requirements of daily chemical products for raw materials.
6. Other Fields: In the coating industry, it serves as a diluent and plasticizer to reduce coating viscosity, accelerate drying speed, and improve coating gloss and flexibility. In geological mineral processing, it acts as an extractant for specific minerals to assist in mineral enrichment and purification. In analytical chemistry experiments, it can also be used as a solvent or reaction medium to support testing work.

Storage：Keep it in a well-closed container and store in a cool, dry and well ventilated warehouse.

Packing：250kg paint drum or galvanized iron drum, IBC drum, or ISO Tank.
