Use of Polyether Polyol

 Polyether polyol is abbreviated as polyether. It is an oligomer whose main chain contains ether bond (—R—O—R—) and the terminal group or side group contains more than 2 hydroxyl groups (—OH). It is prepared by addition polymerization of an initiator (a compound containing an active hydrogen group) with ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO), etc. in the presence of a catalyst. The largest polyether producers are all common polyether polyols. Polyether polyols are produced with glycerol (glycerol) as the initiator and epoxide, by changing the PO and EO addition methods (mixed addition or separate addition), addition ratio, addition order and other conditions.

 

The main purpose

1. Detergent or defoamer

L61, L64, F68 are used to prepare low-foam, high detergency synthetic detergent;

L61 and L81 are used as defoamers in the papermaking or fermentation industry;

F68 is used as an antifoaming agent in the blood circulation of artificial heart-lung machine to prevent air from entering.

 

2. Excipients and emulsifiers

Polyether has very low toxicity and is often used as a pharmaceutical excipient and emulsifier; it is often used in the oral cavity, nasal sprays, eyes, ear drops and shampoos.

 

3. Wetting agent

Polyether is an effective wetting agent and can be used in acid baths for fabric dyeing, photographic development and electroplating. F68 is used in sugar factories. Due to the increased water permeability, more sugar can be obtained.

 

4. Antistatic agent

Polyether is a useful antistatic agent, and L44 can provide long-lasting static protection for synthetic fibers.

 

5. Dispersant

Polyether is used as a dispersant in emulsion paints. F68 acts as an emulsifier during the emulsion polymerization of vinyl acetate. L62 and L64 can be used as pesticide emulsifier, as coolant and lubricant in metal cutting and grinding, and as lubricant during rubber vulcanization.

Difference Between Sodium Laureth Sulfate And Sodium Lauryl Sulfate

Sodium laureth ether sulfate  (SLS) and sodium lauryl ether sulfate (SLES) are surfactants that play a role in foaming products. It is widely believed that the foam produced by a product is its performance. The composition of SLS and SLES reduces the surface tension of water. They can also be used as dispersants to properly mix spices and body spray. SLS and SLES can also be used in a variety of personal care products such as soap, shampoo, shower gel, toothpaste and other foaming products. SLS and SLES are also added to moisturizing lotions and sunscreens because of these properties. The difference between SLS and SLES is in the manufacturing process. SLS undergo a process called ethoxylation. And then you get SLES. Why do we have this ethoxylation process? Because SLS has some mild irritation on the skin, such as dry. The manufactured SLES are more gentle and do not irritate the skin. Many manufacturers do not use SLS because it is irritating. SLES should be softer o...

Two Different Types of Anionic Surfactants

  Anionic surfactant is a kind of product with the longest history, the largest output and the most varieties among surfactants. According to the structure of hydrophilic groups, anionic surfactants can be divided into sulfonates and sulfates, which are the main categories of anionic surfactants.    The  anionic surfactants definition  is a must-known concept for many people working in the chemical industry. The various functions of surfactants are mainly manifested in changing the properties of the liquid surface, liquid-liquid interface and liquid-solid interface, of which the surface (interface) of the liquid is the most important.   Sulfate-type anionic surfactants mainly include fatty alcohol sulfate (also known as primary alkyl sulfate) and secondary alkyl sulfate : 1.  Fatty alcohol sulfate (ester) salt (FAS or AS). The general formula of fatty alcohol sulfate is: ROS0-3M+, R is alkyl, M+ is sodium, potassium, ammonium, ethanolamine and other ca...
