Product Introduction
Industrial-grade dipropylene glycol (abbreviated as DPG) is a well-established, low-toxicity, and highly soluble diol bulk raw material, with an industrial-grade purity of ≥99%.
Overview
Industrial grade dipropylene glycol (DPG) is a high-purity glycol ether alcohol mainly composed of dipropylene glycol isomers, produced through advanced chemical processing to achieve stable physical and chemical properties. As an important industrial solvent and formulation ingredient, DPG combines excellent solvency, low odor, low vapor pressure, and good water compatibility, making it suitable for demanding applications where performance stability and formulation flexibility are required.
Qingdao Jinforest Chem Tech Co., Ltd. supplies industrial grade dipropylene glycol with strict quality control procedures, providing professional chemical solutions for global customers in coatings, inks, resins, cleaning agents, and other industrial fields.
Description
Industrial-grade dipropylene glycol, commonly known as dipropylene glycol or dipropylene glycol in Chinese, and abbreviated as DPG in English, has the common CAS number 25265-71-8, molecular formula C₆H₁₄O₃, and molecular weight 134.17. It is a low-toxicity, highly soluble, multi-purpose glycol that appears as a colorless, transparent, slightly hygroscopic viscous liquid at room temperature.
Unlike fragrance grade DPG, which prioritizes odorlessness and high purity, industrial-grade products have relatively relaxed requirements for odor control and the removal of certain trace impurities (such as aldehydes), but purity is typically maintained above 99%. Industrial-grade DPG is primarily targeted at industries where odor is not a primary concern, such as resins, coatings, and plasticizers, while fragrance grade DPG is specifically designed for applications requiring a high level of sensory experience, such as fragrances and cosmetics.
For customers searching for a reliable DPG supplier from China, product consistency, supply stability, and export capability are important factors. Jinforest Chem provides professional chemical export services, supporting global buyers with flexible packaging options, customized logistics solutions, and complete export documents. Our products are exported to multiple international markets, including Europe, America, Southeast Asia, the Middle East, and South America.
Industrial-grade dipropylene glycol is primarily used in the production of unsaturated polyester resins, alkyd resins, and polyurethanes, and serves as an excellent solvent for nitrocellulose, shellac varnish, and castor oil.
It can also be used to manufacture plasticizers, fumigants, synthetic detergents, textile lubricants, printing inks, and to formulate antifreeze, coolant, brake fluid, and fog liquids for stage fog machines.
Choosing the proper industrial solvent supplier can directly influence production efficiency and product reliability. Qingdao Jinforest Chem Tech Co., Ltd. combines manufacturing capability, quality assurance, and international trade experience to deliver dependable dipropylene glycol solutions for industrial users worldwide.
Why Choose Our Industrial Grade Dipropylene Glycol?
Stable and reliable quality, purity exceeding 99%
Our industrial-grade dipropylene glycol production process undergoes rigorous quality control, typically achieving a purity of over 99%, with some specifications consistently maintaining 99.5% to 99.9%. Key indicators such as moisture content and color meet industrial standards, ensuring consistent performance in resin synthesis, solvent formulation, and other processes.
01
Multi-application range and wide applicability
This product possesses excellent solubility, moderate viscosity, and a high boiling point. It serves as a superior raw material for unsaturated polyester and alkyd resins, and can also be used as a highly efficient solvent and coupling agent in coatings, inks, and cleaning agents. Furthermore, it is used in various industrial applications such as plasticizers, brake fluids, antifreeze, and stage fog liquids, meeting diverse needs across different industries.
02
Low toxicity and environmentally friendly, with controllable safety risks
Compared to other diols such as ethylene glycol, dipropylene glycol is less toxic, less irritating to the skin, and has good biodegradability, better meeting current green chemical industry requirements. With proper handling under well-ventilated conditions, occupational health risks can be effectively reduced.
03
Well-established supply chain and flexible delivery options
We have established a comprehensive warehousing and logistics system, offering various packaging specifications such as iron drums and IBC containers, and supporting full-cycle services from small-batch samples to bulk purchases. Stable supply capacity reduces customer inventory pressure, ensuring continuous production unaffected by raw material shortages.
04
Economical and practical, with outstanding cost-effectiveness
Among similar industrial solvents and resin raw materials, industrial-grade dipropylene glycol is relatively reasonably priced. Its versatility allows for multiple uses, simplifying procurement and reducing overall operating costs. For large-scale production focused on cost control, it is a choice that combines performance and economic efficiency.
05
Applications
A common raw material for producing unsaturated polyester resins, alkyd resins, and polyurethanes; the resulting resins exhibit excellent flexibility, resistance to cracking and weathering, and stable resistance to yellowing during long-term use.
Serves as an excellent solvent for nitrocellulose, shellac varnish, and castor oil; also widely used in formulations for plasticizers, synthetic detergents, textile lubricants, and printing inks.
Used as a component in antifreeze, coolants, and brake fluids, and serves as a common core ingredient for "fog fluid" in stage fog machines.
