What is propylene glycol 2000?
Polypropylene Glycol 2000 (PPG 2000) is used in a production of a wide range of products, including such diverse. Commodities as polyester resins, engine coolants, latex paints, heat transfer fluids, and deicing compounds. It is employed as a solvent, heat transfer medium, or as a chemical intermediate, taking.
How is polypropylene glycol made?
Polypropylene glycol is produced by ring-opening polymerization of propylene oxide. The initiator is an alcohol and the catalyst a base, usually potassium hydroxide. When the initiator is ethylene glycol or water the polymer is linear. Conventional polymerization of propylene oxide results in an atactic polymer.
Is polypropylene glycol the same as propylene?
Abstract: Propylene Glycol is an aliphatic alcohol manufactured as a reaction product of propylene oxide and water. Polypropylene Glycol is a polymer formed by adding propylene oxide to dipropylene glycol.
Is polypropylene glycol a crystalline?
Generally, PPO and PTMG (Mn ≥ 2000 Dalton) are amorphous and crystalline polymers, and their blends present a white crystallizing solid (shown in the inset as (a) in Figure 5) at ambient temperature for PTMG crystallization.
What is polypropylene glycol used for?
Polypropylene glycols are liquids, mostly insoluble in water, used to suppress foaming in industrial processes and for making polyurethane resins, hydraulic fluids, and various other materials.
Is polypropylene glycol an alcohol?
What Is Propylene Glycol? Propylene glycol is a synthetic food additive that belongs to the same chemical group as alcohol. It is a colorless, odorless, slightly syrupy liquid that is a bit thicker than water.
What is propylene used for?
Propylene is used mainly to produce polypropylene plastics for injection molding and fibers and for manufacturing cumene (used in phenol production). Propylene is also used to make propylene oxide, acrylic acid, oxo alcohols and isopropanol.
Is polypropylene glycol a antifreeze?
Propylene glycol is added to food and beverages to improve taste and texture. It is not antifreeze. It is considered safe to use in the amount present in foods.

Is glycol a glycerin?
Alcohols with two OH groups on adjacent carbon atoms are commonly known as glycols. Commonly called glycerol or glycerin, 1,2,3-propanetriol is the most important trihydroxy alcohol. Like the two glycols, it is a sweet, syrupy liquid. Glycerol is a product of the hydrolysis of fats and oils.
What is the formula for propylene glycol and polypropylene?
Polypropylene glycol is an addition polymer of propylene glycol and water. It is represented by the formula HO (C3H6O)nC3H6OH in which n represents the average number of oxypropylene groups.
How is polypropylene glycol soluble in water?
Polypropylene glycol is soluble in water and in certain organic solvents as aliphatic ketones and alcohols and insoluble in ether and in most aliphatic hydrocarbons. In this paper, we discuss recent advances in the preparation of various TiO2 porous structures via hard and soft-templating routes.
How is the toxicity of polypropylene glycol determined?
1 Toxic Effects and Modes of Action The acute toxicity of ingested polypropylene glycol (PPG) depends on its molecular weight and is moderate to low. With increasing molecular weight, the toxicity increases initially to reach a maximum for PPG600 and PPG750 and then decreases at higher molecular weights.
What are the synonyms for polypropylene glycol?
Synonyms: Polypropylene glycol; Poly (propylene oxide). Used as solubilizing agent, antifoaming agent, lubricant, antistatic agent, plasticizing agent, parting agent, viscosity conditioning agent and chemical intermediate in the industry. Package: 1000 Kg / IBC drum or 200 Kg / metal drum (Net weight).
