Diluting this 100% base allows operators to maximize specific heat capacity, as pure glycol transfers heat less efficiently than a balanced glycol-water mixture. For industries evaluating heat transfer options, this product delivers the critical food-safe advantage over highly toxic ethylene glycol, ensuring operational continuity in environments where incidental contact with consumables is a risk. With a flash point of 104°C (219.2°F) and high water solubility, it integrates readily into existing aqueous systems while remaining non-flammable under ambient conditions.\u003c\/p\u003e\n\n\u003ch3\u003eQuick Specs\u003c\/h3\u003e\n\u003ctable style=\"border-collapse:collapse;margin:0 0 1.25rem 0;font-size:0.95rem;\"\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:6px 14px 6px 0;color:#555;\"\u003eCAS Number\u003c\/td\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e\u003cstrong\u003e57-55-6\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:6px 14px 6px 0;color:#555;\"\u003eChemical Formula\u003c\/td\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e\n\u003cstrong\u003eC\u003csub\u003e3\u003c\/sub\u003eH\u003csub\u003e8\u003c\/sub\u003eO\u003csub\u003e2\u003c\/sub\u003e\u003c\/strong\u003e (propane-1,2-diol)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:6px 14px 6px 0;color:#555;\"\u003eMolecular Weight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e\u003cstrong\u003e76.09 g\/mol\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:6px 14px 6px 0;color:#555;\"\u003eGrade \/ Concentration\u003c\/td\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e\u003cstrong\u003eUSP-NF \/ 99.9 wt% typical\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:6px 14px 6px 0;color:#555;\"\u003eBoiling Point\u003c\/td\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e188.2°C (370.4°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:6px 14px 6px 0;color:#555;\"\u003eMelting Point\u003c\/td\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e-59°C (-74.2°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:6px 14px 6px 0;color:#555;\"\u003eFlash Point\u003c\/td\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e104°C (219.2°F), closed cup\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:6px 14px 6px 0;color:#555;\"\u003eSpecific Gravity\u003c\/td\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e1.033–1.039 (20°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:6px 14px 6px 0;color:#555;\"\u003eWater Content\u003c\/td\u003e\n\u003ctd style=\"padding:6px 0;\"\u003e\u0026lt;0.5% (typical 0.1%)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:6px 14px 6px 0;color:#555;\"\u003eDOT Hazard Class\u003c\/td\u003e\n\u003ctd style=\"padding:6px 0;\"\u003eNot Regulated\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eApplication Deep-Dives\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDatacenter liquid cooling loops:\u003c\/strong\u003e Pure 100% PG USP is the engineering choice for rear-door heat exchanger and direct-liquid-cooling rigs where operators dial in their own glycol:water ratio (typically 25–40% by volume) to balance freeze protection against pump head and heat capacity.

This specific ratio represents the industry standard for balancing maximum freeze defense with acceptable fluid viscosity, ensuring mechanical pumps do not overwork during cold-weather startups. The integration of specialized industrial corrosion inhibitors specifically protects closed-loop operations by preventing oxidation, scaling, and degradation across mixed-metal components, including copper, brass, steel, and cast iron.

formulated to deliver moderate freeze and burst protection in closed-loop systems. When engineers weigh ethylene versus propylene, they choose this USP-grade propylene glycol because it provides a non-toxic, food-safe thermal solution, completely avoiding the severe toxicity risks inherent to ethylene glycol. At a precise 30% concentration, this clear, colorless liquid balances necessary freeze protection with excellent thermal conductivity, preventing the sluggish flow rates and excess pump wear caused by overly concentrated glycol mixtures. Because this specific product is uninhibited, it contains no added chemical buffers, making it the exact formulation required for specialized processes that cannot tolerate the introduction of foreign corrosion inhibitors.\u003c\/p\u003e\n\n\u003ch3\u003eBest Applications for This Grade\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFood Processing and Beverage Cooling:\u003c\/strong\u003e Commonly applied in brewery chillers, dairy facilities, and food plant process cooling lines where a non-toxic, USP grade liquid mitigates the severe health risks associated with incidental consumable contact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHVAC and Building Systems:\u003c\/strong\u003e Commonly applied in commercial building loops located in moderate climates.
