The viscosity of PPG with different brands is very different

The viscosity of PPG with different brand varies greatly, and the color will vary according to the brand. Its monoester is a non-ionic surfactant and can also react with alcohol to form ether. It is also used to prepare alkyd resin, emulsifier, demulsifier, lubricating oil and plasticizer. The molecular weight of PPG is 400-2050, which is non-volatile and non corrosive. The lower molecular weight polymer is soluble in water, the higher molecular weight polymer is only slightly soluble in water, soluble in oil, many hydrocarbons, aliphatic alcohols, ketones, esters, etc.

Polyethylene glycol PEG as a chemical finishing agent, the finished fabric has the characteristics of smoothness, softness, strong elastic wool shape, fullness of hand, and can improve the tear strength and wear resistance, as well as some antistatic and antifouling properties. Compared with diethylene glycol or triethylene glycol, polyethylene glycol is not volatile, and its hygroscopicity is less than that of low molecular weight diol and glycerin, so the mixture of polyethylene glycol PEG is not sensitive to the change of environmental humidity, even if it is stored for a long time, it is still high quality. Peg is widely used in cosmetics, pharmaceutical, chemical fiber, rubber, plastics, paper, paint, electroplating, pesticide, metal processing and food processing industries.

The monomers of PPG are nonionic surfactants

PPG is noncorrosive, and its monoester is a non-ionic surfactant, which can react with alcohol to form ether. PPG is the solvent of vegetable oil, resin and paraffin. It is also used to prepare alkyd resin, emulsifier, demulsifier, lubricating oil and plasticizer. PPG can be used as antifoaming agent in paint and hydraulic oil, antifoaming agent in synthetic rubber and latex processing, refrigerant and coolant for heat transfer fluid, viscosity improver. It can be used as mold release agent, solubilizer, additive of synthetic oil, additive of water soluble cutting fluid, roller oil, hydraulic oil, high temperature lubricant, internal lubricant and external lubricant of rubber.

Polyethylene glycol PEG has good water solubility and is widely used in cosmetics, pharmaceuticals, chemical fiber, rubber, plastics, paper making, paint, electroplating, pesticides, metal processing and food processing industries. Peg is soluble in water, ethanol and many other organic solvents. With the increase of molecular weight, its hygroscopic capacity decreases correspondingly. With the difference of average molecular weight, its properties also vary. Peg can be compatible with protein, oxidized starch, nitrocellulose, polyvinyl acetate and corn gluten. It is insoluble in beeswax, castor oil, gelatin, gum Arabic, mineral oil, olive oil and paraffin.
