Poly(propylene glycol) 2000 is a macromolecule composed of repeating propyleneoxy units. Poly(propylene glycol) 2000 is a hydroxypolyether and a poly(ether) macromolecule.

PPG 2000 is 100% active polypropylene glycol based defoamer. PPG 2000 is recommended for rubber processing, foam inhibition and brake fluid formulations.

PPG-2000 is a 2,000 molecular weight polyether diol. It is designed to be an intermediate for a variety of polyurethane applications. 


Polypropylene glycol or polypropylene oxide is the polymer of propylene glycol. Chemically it is a polyether, and, more generally speaking, it's a polyalkylene glycol (PAG). 
The term polypropylene glycol or PPG is reserved for low to medium range molar mass polymer when the nature of the end-group, which is usually a hydroxyl group, still matters. 
The term "oxide" is used for high molar mass polymer when end-groups no longer affect polymer properties. 
Between 60 and 70% of propylene oxide is converted to polyether polyols by the process called alkoxylation


Polymerization
Polypropylene glycol 2000 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. 
With a multifunctional initiator like glycerine, pentaerythritol or sorbitol the polymer branches out.


Properties
PPG 2000 has many properties in common with polyethylene glycol. The polymer is a liquid at room temperature. 
Solubility in water decreases rapidly with increasing molar mass. 
Secondary hydroxyl groups in PPG are less reactive than primary hydroxyl groups in polyethylene glycol. 
PPG 2000 is less toxic than PEG, so biotechnologicals are now produced in PPG.


Linear polypropylene glycols (PPG) are difunctional polyols mainly used for CASE (coatings, adhesives, sealants, elastomers) applications and as for the production of binders and foams. 
ATAMAN CHEMICALS offers various polypropylene glycols with molar weights rangin from 500 to 4000 g/mol. 


Linear polypropylene glycols (PPG) are difunctional polyols mainly used for CASE (coatings, adhesives, sealants, elastomers) applications and as for the production of binders and foams. 
As ATAMAN we offer various polypropylene glycols with molar weights rangin from 500 to 4000 g/mol. 
PPGs with a low molecular weight are produced by KOH catalysis. 
PPGs with a high molecular weight are also available as DMC catalyzed products or are solely produced by the latter technique, which lowers the content of unsaturated, monofunctional by-products to a minimum.

Polypropylene glycol 2000 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. 
Polypropylene glycol 2000 is soluble in water and in certain organic solvents as aliphatic ketones and alcohols and insoluble in ether and in most aliphatic hydrocarbons.


PPG-2000 is a 2,000 molecular weight polypropylene glycol polyol containing only propylene oxide. 
PPG-2000 polyol can be used in polyurethane foam, coatings, and elastomers.
PPG-1000 polyol can be used in a number of urethane applications including flexible foam, elastomers, sealants and coatings. 
Hydroxyl Value 54.5-57.5 mg KOH/g, viscosity at 25C is 370 cps.

PPG-2000 is suitable for polyurethane coatings, adhesives, sealants, elastomers, and potting compounds.

PPG-2000 is extensively employed in the production of filled as well as unfilled elastomer, sealants, adhesives, and encapsulation compounds. 
PPG-2000 is widely used in the manufacture of prepolymers, high flexibility foam, and coatings

PPG 2000 is a polypropylene glycol with an average molecular weight of 2000. 
PPG 2000 is a 100% active, nearly colorless, somewhat viscous liquid polypropylene glycols are compatible with a wide range of other liquids, and at 77°F, are miscible in all proportions with most organic aromatic compounds, halogenated hydrocarbons, alcohols, aldehydes and acids. 
In addition, they show good solubility with some animal and vegetable oils, and modified alkyd resins. 
PPG 2000, as this product is also known, is a clear, viscous liquid at room temperature. 
PPG 2000 has a higher pour point and, unlike the lower molecular weight PPGs, is partially soluble in water at 25 °C. 
PPG 2000 loses its water solubility at higher temperatures. 
Like all polypropylene glycols, Polyglycol 2000 is soluble in all proportions with any organic solids and liquids, the main exception being long chain aliphatic hydrocarbons. 
Polyglycol 2000 possesses excellent lubricity and has a low vapour pressure. 
Under extreme heating conditions it does not form coke not does it form a varnish. 
Decomposition products are low boiling products that are either lost as volatiles or soluble in the polypropylene glycol.

Poly(propylene glycol) Chemical Properties,Uses,Production

Chemical Properties
Viscous colourless liquid (whose viscosity depends upon the average

Uses
Hydraulic fluids, rubber lubricants, antifoam agents, intermediates in urethane foams, adhesives, coatings, elastomers, plasticizers, paint formula- tions, laboratory reagent.

Definition
ChEBI: A macromolecule composed of repeating propyleneoxy units.

General Description
Colorless liquid that is odorless or has a mild sweet odor. May float or sink in water.

Reactivity Profile
Poly(propylene glycol) is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. 
They react with oxoacids and carboxylic acids to form esters plus water. 
Oxidizing agents convert them to aldehydes or ketones. 
Alcohols exhibit both weak acid and weak base behavior. 
They may initiate the polymerization of isocyanates and epoxides.

Health Hazard
The compound has a very low toxicity; few, if any, symptoms will be observed. 
Contact of liquid with eyes causes slight transient pain and irritation similar to that caused by a mild soap.

Safety Profile
Poison by intraperitoneal and intravenous routes.
When heated to decomposition it emits acrid smoke and irritating fumes.

Polypropylene Glycols
ATAMAN polypropylene glycols are relatively easy to store and handle. 
They can be stored in bulk in steel tanks, which should be padded with nitrogen or any other inert gas to prevent air from entering the tank. 
If slight iron pickup and color changes cannot be tolerated then the storage tanks should be constructed from stainless steel.
To ease the handling of polypropylene glycols somewhat, higher storage temperatures should be considered to keep the viscosity of the polyglycols within limits suitable for the pumping equipment available. 
The maximum storage temperature should not exceed 40°C to avoid the risk of product degradation. 
Pipelines may also require insulation and/or tracing to maintain suitable product temperatures.

Although PPGs have very low pour points, especially PPG 2000 and PPG 4000 become very viscous at low temperatures. 
Consequently it is recommend that they be stored in tanks which are well insulated and heated. 
Externally located heating devices are preferable to internally sited ones. 
With external heating the risk of accelerating product deterioration is greatly reduced.
Similarly drums should be stored under cover, or preferably inside a warehouse, to maintain the temperature of the polyglycol at a level which allows for easy discharge.

The shelf life of properly stored bulk and unopened drums is, at least, 24 months.
Polyglycols 2000 and 4000 are considered to be low in acute oral toxicity, whereas polyglycols PPG 400, PPG 600, PPG 1000 are considered to be low to moderate in acute oral toxicity.
They cause no significant skin irritation or sensitization and are not reportedly absorbed in any appreciable amount. 
Direct contact with the eyes may cause slight temporary irritation, similar in character to that caused by mild soap. 
Consequently it is recommended that eye protection should be employed and viewed as the minimum level of safety equipment required when working with polypropylene glycols.
