PEAK Commercial & Industrial is a market-leading supplier of Ethylene Glycol, Propylene Glycol, Methanol products backed by the most comprehensive supply network in the industry. PEAK Commercial & Industrial ensures that the products you need are always there when you need them.





Ethylene glycol is commonly used in many industrial applications, including antifreeze and coolant. It also is used as a raw material in the production of a wide range of products, including polyester fibers (clothing, carpet), fiberglass, and polyethylene terephthalate (PET) resin, which is used in container (plastic bottle) manufacture. OWI offers Industrial Grade Monoethylene Glycol as well as Diethylene Glycol and Triethylene Glycol.

Diethylene Glycol (DEG) is used in the manufacture of saturated and unsaturated polyester resins, polyurethanes, and plasticizers. DEG is used as a building block in organic synthesis, e.g. of morpholine and 1,4-dioxane. It is a solvent for nitrocellulose, resins, dyes, oils, and other organic compounds. It is a humectant for tobacco, cork, printing ink, and glue. It is also a component in brake fluid, lubricants, wallpaper strippers, artificial fog and haze solutions, and heating/cooking fuel. In personal care products (e.g. skin cream and lotions, deodorants), DEG is often replaced by selected diethylene glycol ethers. A dilute solution of diethylene glycol can also be used as a cryoprotectant; however, ethylene glycol is much more commonly used. Most ethylene glycol antifreeze contains a few percent diethylene glycol, present as an byproduct of ethylene glycol production.


Triethylene Glycol (TEG) is used by the oil and gas industry to “dehydrate” natural gas. It may also be used to dehydrate other gases, including CO2, H2S, and other oxygenated gases. It is necessary to dry natural gas to a certain point, as humidity in natural gas can cause pipelines to freeze, and create other problems for end users of the natural gas. Triethylene glycol is placed into contact with natural gas, and strips the water out of the gas. Triethylene glycol is heated to a high temperature and put through a condensing system, which removes the water as waste and reclaims the TEG for continuous reuse within the system.


Propylene glycol is used in waterbased acrylic architectural paints to extend dry time which it accomplishes by preventing the surface from drying due to its slower evaporation rate compared to water. Forty-five percent of propylene glycol produced is used as chemical feedstock for the production of unsaturated polyester resins. In this regard, propylene glycol reacts with a mixture of unsaturated maleic anhydride and isophthalic acid to give a copolymer. This partially unsaturated polymer undergoes further crosslinking to yield thermoset plastics. Related to this application, propylene glycol reacts with propylene oxide to give oligomers and polymers that are used to produce polyurethanes.

Propylene glycol is also used in various edible items such as coffee-based drinks, liquid sweeteners, ice cream, whipped dairy products and soda. Vaporizers used for delivery of pharmaceuticals or personal-care products often include propylene glycol among the ingredients. In alcohol-based hand sanitizers, it is used as a humectant to prevent the skin from drying. Propylene glycol is used as a solvent in many pharmaceuticals.

Propylene glycol is commonly used to de-ice aircraft. The freezing point of water is depressed when mixed with propylene glycol. It is used as aircraft de-icing fluid. Water-propylene glycol mixtures dyed pink to indicate the mixture is relatively nontoxic are sold under the name of RV or marine antifreeze. Propylene glycol is frequently used as a substitute for ethylene glycol in low toxicity, environmentally friendly automotive antifreeze. It is also used to winterize the plumbing systems in vacant structures.


Methanol is commodity wide ranging in application. It is used to produce chemical derivatives including formaldehyde, acetic acid, solvents, olefins and methyl methacrylate from which numerous every day products are produced. It is also prevalent in fuel & fuel-blending applications.
