Polyethylene glycol Pharma Grade

Polyethylene Glycol、PEG    

Chemical Structure:HO(CH2CH2O)nH 
Commodity Name:Polyethylene Glycol、PEG
Properties and Uses:Normally, these non-ionic products are soluble in water and most organic solvents except paraffin and benzoglycols. These products will remain their properties while soluble in water and they are not toxic or irritant. They are used to produce binder,anti-static agent and softener with their good lubricating, wetting and dispersing ability. They are usually used to produce a medium in an organic synthesis,a carrier at a high temperature,humectqant and inorganic salt’s solubilizing agent in daily chemistry industries,adjusting the melting point and viscosity as matrix ,lubrication agent and softener in cosmetics and medicine ;promoting and adjusting sulfidationas dispersion agent,lubrication agent and dispersion agent white carbon black on rubber;increasing the polyester’s dyeability and making the textile products more comfortable as dyeable polyester monomer in chemical fiber; widely application in plastics, papermaking ,paints, electroplating ,pesticide, melt and food processing industries.
Quality indexes:These products are made with the most advanced ethoxylation and catalytic polymerization technology.They feature accurate molecular weight, narrow dispersing ability and white color. Their quality is as good as those foreign ones and high molecular products are unique in China.

remark 1:date with “*” are measured in 25% water solution 
remark 2:Refined PEGs are clear and colorless while fused,the content of buring residues is less 0.2%,arsenate is less 3PPM,heavy metal is less 5PPM. 
Packaing:Liquid and paste PEGs are packed in 200 kg galvalized drum.Solid PEGs after flaked is packed in 25kg plastic lined carton or bag. 
Storage and Transporttion:these products ae intoxic and hard to burn,so they they can be dealt with as common chemicals,and should be stored in dry and ventilated places avoiding sunshine and rain,and storage time is two years.
