Application Guidance

Polyethylene Glycol 200 (PEG 200) - Technical Grade (Technical) is a glycol-based heat-transfer and freeze-protection fluid. Concentration sets the freeze and burst protection; the inhibitor package sets how long the system stays protected from corrosion.

Closed-loop heat transfer and process cooling
Data-centre and chilled-water freeze protection
HVAC hydronic loops and glycol makeup
Freeze and burst protection for idle or seasonal systems
Humectant and carrier applications (USP/food-grade propylene glycol only)

Verify concentration against the required freeze and burst protection, and confirm elastomer and metallurgy compatibility for the service temperature. Ethylene glycol is toxic by ingestion and must not be used where incidental food or potable contact is possible — specify a propylene glycol grade for those services.

Storage & Handling

Recommended Storage: Store in the original container, tightly closed, in a cool, dry, well-ventilated place out of direct sunlight; protect from moisture and prolonged exposure to heat and air. Use promptly after opening. Stainless steel, polypropylene or polyethylene containers are suitable.Adjudicated
Handling Precautions: Chemical-resistant gloves and splash goggles. Ethylene glycol grades are toxic by ingestion and must be kept away from food, drink and animals; propylene glycol grades are not. Avoid contact with hot surfaces and hot process equipment. Inhibitor packages deplete in service — monitor rather than top up blindly.Class-level guidance — not product-specific; the SDS controls.
Incompatibilities: Strong oxidizing agents; strong acids; strong bases.Adjudicated
Shelf Life: Consult Technical Services for product-specific shelf life

For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
