Propyleneglycol solution 40%

40% Propylene Glycol Solution Without Additives

What Is This Product?

40% Propylene Glycol Solution consists of propylene glycol and distilled water in a specified ratio.
The product is supplied as a prepared solution, eliminating the need to mix propylene glycol with water on site when a large volume of a specified concentration is required.
However, this product is not a formulated inhibited heat transfer fluid.
It contains no:

• corrosion inhibitors;
• antifoaming agents;
• stabilizing additives;
• other functional components typically used in formulated heat transfer fluids.

Applications of 40% Propylene Glycol Solution

The product can be used:

• as a process raw material;
• as a component in industrial processes;
• for further manufacturing of other products;
• for preparing proprietary formulations;
• in process equipment that permits the use of an uninhibited aqueous propylene glycol solution;
• in processes requiring propylene glycol at a specified concentration.

Suitability for specific equipment depends on its design, materials of construction, and the equipment manufacturer’s requirements.

More information

Other Concentrations Available

LLC “AO Khimprom” manufactures aqueous propylene glycol solutions in different concentrations.
This is convenient when a process requires a ratio of propylene glycol to distilled water other than the standard 40% concentration.
When ordering, specify:

• required concentration;
• required quantity;
• preferred packaging.

Products in this category are manufactured without a functional additive package.
For more information about the relationship between propylene glycol concentration, crystallization onset temperature, and other properties, see the Novohim Reference Center article “Propylene Glycol Solution”.

Propylene Glycol Solution vs. FREEZLIGHT®

These products differ in both composition and intended use.
Propylene Glycol Solution
Composition:
propylene glycol + distilled water.
No functional additives are included.
The product is intended primarily for industrial processes, manufacturing, and other applications requiring an aqueous propylene glycol solution of a specified concentration.
FREEZLIGHT® Heat Transfer Fluid
FREEZLIGHT® contains an aqueous propylene glycol base combined with a specially selected functional additive package.
These formulated heat transfer fluids are intended for long-term circulation in heating, cooling, and heat transfer systems according to the specifications of the particular product grade.
If the system requires corrosion protection and other functional properties, a formulated FREEZLIGHT® heat transfer fluid should be used instead of a plain propylene glycol solution.

When to Choose a Solution Without Additives

40% Propylene Glycol Solution is appropriate when:

• a specific propylene glycol concentration is required;
• additives are not required by the process;
• the product is used as a raw material;
• the customer formulates the final product independently;
• the equipment permits the use of an uninhibited aqueous propylene glycol solution;
• there is no need for a formulated heat transfer fluid with a functional additive package.

When to Choose a Formulated Heat Transfer Fluid

FREEZLIGHT® is the more appropriate option when a ready-to-use working fluid is required for:

• heating systems;
• cooling systems;
• heat transfer systems;
• heat pumps;
• other circulation systems requiring a functional additive package.

The Novohim range includes FREEZLIGHT® propylene glycol-based heat transfer fluids for different temperature conditions, including products with crystallization onset temperatures of −20 °C and −32 °C.

Limitations

40% Propylene Glycol Solution should not automatically be used:

• as a direct replacement for a formulated inhibited heat transfer fluid;
• in systems where the equipment manufacturer requires a fluid containing corrosion inhibitors;
• in mixed-metal systems without assessing corrosion risks;
• as an automotive antifreeze;
• in applications requiring specific approvals;
• as a food-grade or pharmaceutical product solely because it contains propylene glycol.

The properties of pure propylene glycol should not be automatically attributed to a 40% aqueous solution without considering its actual concentration.

Material Compatibility and Equipment Use

Before using the solution in a circulation or process system, check the equipment manufacturer’s requirements.
Consider the materials used in:

• piping;
• heat exchangers;
• pumps;
• seals;
• gaskets;
• membranes;
• soldered joints;
• sealants.

Because this product contains no corrosion inhibitors, it should not be described as providing corrosion protection for all metals in a system.

Preparation for Use

If the solution is used as a working fluid in a process circuit:

1. Confirm that the solution is suitable for the equipment.
2. Remove the previous working fluid.
3. Clean the system of contamination and deposits.
4. Remove as much residual water as possible if maintaining the specified concentration is important.
5. Check the system for leaks.
6. Fill the system with the prepared solution.
7. Ensure proper circulation and uniform mixing.

Residual water in the system will reduce the actual propylene glycol concentration.

Does the 40% Solution Need to Be Diluted

If a 40% concentration is required, no further dilution is necessary.
Adding water reduces the propylene glycol concentration and changes the physical properties of the solution.
If another concentration is required, a solution with the specified ratio of propylene glycol to distilled water can be manufactured to order.

You can buy propylene glycol concentrate, as well as propylene glycol solution from the warehouse in Kharkiv and with delivery throughout Ukraine.

Storage and Safety

Store the product in tightly closed, properly labelled containers and protect it from contamination with foreign substances.
Follow the Safety Data Sheet and standard procedures for handling industrial chemical products.
Claims such as “absolutely safe”, “harmless”, or “100% environmentally friendly” should not be used without appropriate documented substantiation.

Frequently Asked Questions

What does the 40% propylene glycol solution contain?
Propylene glycol and distilled water.
Does the product contain corrosion inhibitors?
No. It contains no corrosion inhibitors or other functional additives.
Is this a ready-to-use heat transfer fluid for a heating system?
It is a prepared aqueous propylene glycol solution of a specified concentration, but it is not a formulated inhibited heat transfer fluid.
If the system requires a functional additive package, choose a FREEZLIGHT® heat transfer fluid.
Can I order a different concentration?
Yes. Aqueous propylene glycol solutions of other concentrations can be manufactured to order.
Are additives included in solutions of other concentrations?
No. When an aqueous propylene glycol solution is ordered, it consists of propylene glycol and distilled water without a functional additive package.
What determines the crystallization onset temperature?
Primarily the propylene glycol concentration.
See the Novohim Reference Center article “Propylene Glycol Solution” for the concentration and crystallization onset temperature table.
Can this product be used in a heating system?
Only if the system design and equipment manufacturer permit the use of an aqueous propylene glycol solution without functional additives.
Where a corrosion inhibitor package is required, use a formulated heat transfer fluid.
