{"product_id":"ethylene-glycol-acs-grade","title":"Ethylene Glycol ACS Grade","description":"\u003ch2\u003eWhy Ethylene Glycol ACS Grade\u003c\/h2\u003e\n\u003cp\u003eEthylene Glycol ACS Grade is an uninhibited, 100% concentrated diol that meets strict American Chemical Society purity standards, making it the required choice for rigorous laboratory environments, analytical testing, and sensitive industrial processes. At 100% concentration, this chemical freezes at approximately 9°F (-13°C) and must be diluted with distilled or deionized water on-site to unlock its full freeze protection capabilities, which can reach -60°F (-51°C) when mixed to a 60\/40 ratio. Because this formulation contains no added corrosion inhibitors, buyers select this specific grade to build highly customized heat transfer fluids with their own proprietary additive packages.\u003c\/p\u003e\n\n\u003ch3\u003eBest Applications for This Grade\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCommonly applied in custom industrial heat transfer loops where facility engineers dilute the pure, 100% concentration to match their exact regional climate freeze protection curve, while independently dosing custom corrosion inhibitor packages tailored to their specific system metallurgy.\u003c\/li\u003e\n\u003cli\u003eCommonly applied in laboratory environments and chemical synthesis that demand strict ACS grade purity, ensuring trace metals, chlorides, and organic impurities do not disrupt sensitive analytical testing or compromise the yield of complex chemical reactions.\u003c\/li\u003e\n\u003cli\u003eCommonly applied in municipal and industrial wastewater treatment operations as a highly soluble, raw carbon source for denitrification processes, providing a pure chemical feed to support microbial activity without introducing unwanted stabilizing additives into the water stream.\u003c\/li\u003e\n\u003cli\u003eCommonly applied in the manufacturing of polyester resins, alkyd resins, and synthetic fibers, where the uninhibited, clear, colorless liquid acts as a highly reactive diol intermediate requiring exact reaction stoichiometry.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhen to Choose a Different Grade\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIf your industrial closed-loop system consists of standard HVAC metals (like copper, brass, and steel) and you need built-in protection against degradation while maintaining high purity, select Ethylene Glycol Inhibited ACS Grade.\u003c\/li\u003e\n\u003cli\u003eIf your operation requires a pre-inhibited fluid but does not demand the strict purity limits of an ACS certification, select 100% Ethylene Glycol Inhibited to build your own diluted freeze protection mixtures.\u003c\/li\u003e\n\u003cli\u003eIf you want to completely avoid the labor and water-quality risks of on-site mixing and need a pre-diluted fluid for severe winter climates, select Ethylene Glycol 60\/40 for maximum freeze protection.\u003c\/li\u003e\n\u003cli\u003eIf your system is located in a moderate climate and you need a ready-to-pump, pre-mixed solution to prevent burst pipes during lighter freezes, select Ethylene Glycol 30\/70 or Ethylene Glycol 50\/50 based on your calculated temperature threshold.\u003c\/li\u003e\n\u003cli\u003eIf you require a pure, uninhibited base fluid specifically processed for the stringent particulate and trace metal limits of wafer fabrication or electronics manufacturing, select Ethylene Glycol Semiconductor Grade.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Alliance Chemical","offers":[{"title":"1 Quart \/ 1
