Polytetrahydrofuran Polymer Science

Polytetrahydrofuran is a white waxy solid that is easily soluble in alcohols, esters, ketones, aromatic hydrocarbons, and chlorinated hydrocarbons, but insoluble in fatty hydrocarbons and water. When the temperature exceeds room temperature, it will turn into a transparent liquid

Easy to dissolve in alcohols, esters, ketones, aromatic hydrocarbons, and chlorinated hydrocarbons, insoluble in fatty hydrocarbons and water. When the molecular weight increases, the solubility decreases. At room temperature, PTMEG has water absorption properties. Its water absorption depends on the size of its molecular weight

Polytetrahydrofuran is mainly used as a block copolymerpolyurethaneOr block polyetherpolyesterThe soft chain segment. fromaverage molecular weightBlock polyurethane rubber made from 1000 polytetrafluoroethylene can be used as tires, transmission belts, gaskets, etc; It can also be used for coatings, synthetic leather, films, etc. The block polyether polyester produced is a thermoplastic elastomer.average molecular weight2000% tetrahydrofuran can be used to producePolyurethane elastic fiberIn 2008, it was reported that block polyurethane made from polytetrafluoroethylene had good anticoagulant properties and could be used asMedical polymermaterial
