Buy MPG with Demi-Water Mixtures in Bulk, Drums and IBCs – Custom Blend Ratios Available
Rotterdam Chemicals Group supplies customized mixtures of Mono Propylene Glycol (MPG) and Demineralized Water (Demi-Water) for industrial and technical applications where stable thermal performance, reliable freeze protection, and consistent fluid quality are required. These ready-to-use MPG and Demi-Water blends support cooling and heat transfer systems, antifreeze formulations, and a wide range of technical process applications.
By combining MPG with mineral-free Demi-Water, the mixture delivers predictable system behaviour while supporting lower scaling risk and improved corrosion control in closed-loop circuits. Blend ratios can be tailored to your required freezing point, viscosity, and operating conditions.
Rotterdam Chemicals Group supplies MPG and Demi-Water mixtures in multiple ratios to match your operating conditions. Typical ratios include MPG/Demi-Water 20/80, 30/70, 40/60, and 50/50. Other ratios are available upon request to support specific freezing point or viscosity targets.
What is the MPG and Demi-Water Mixture?
A mixture of Mono Propylene Glycol (CAS 57-55-6) and Demineralized Water (CAS 7732-18-5) is a clear, colourless liquid formulated to deliver a balanced combination of thermal control, freeze point depression, and compatibility with technical systems. MPG is fully miscible with water and valued for its heat transfer and freeze protection performance. Demi-Water provides a low-mineral, low-conductivity base that supports consistent behaviour in closed-loop systems and reduces the risk of mineral deposits.
Because the ratio of MPG to Demi-Water can be customized, the mixture is used when buyers want a ready-to-use fluid matched to specific performance requirements, rather than blending on-site.
Applications Across Industries
Antifreeze and Freeze Protection
Used for freeze protection, deicing, and anti-icing applications in industrial, infrastructure, and transportation systems where controlled freezing point depression and low toxicity are required.
Automotive and Industrial Fluids
Used in coolant and antifreeze formulations where MPG is preferred and a mineral-free water base supports system reliability.
Chemical Formulations and Dilutions
Used as a controlled dilution medium where consistent fluid properties and compatibility with process equipment are required.
Industrial Utilities and Technical Use
Supports utility and process applications where reliable water quality and predictable mixture performance are important.
Food Industry (USP Grade Only)
Used as a humectant, carrier, and preservative in food products, including applications in breweries and dairies.

Frequently Asked Questions (FAQ)
Why choose a pre-mixed MPG and Demi-Water blend?
A pre-mixed blend reduces on-site handling and ensures consistent ratio control, supporting predictable performance in closed-loop systems.
Can you supply a specific MPG percentage?
Yes. Blend ratios are customizable. Common ratios include 20/80, 30/70, 40/60, and 50/50, with other ratios available on request.
What packaging formats are available?
The mixture is supplied in bulk, drums, and IBCs. ISO tank supply can be arranged on request depending on volume and route.
Is a high-purity blend available?
Yes. High-purity blends can be supplied on request for applications requiring tighter control of conductivity, dissolved solids, or purity specifications.
