The properties of polyester
WebbFor instance, this fabric is present in almost every kind of form-fitting underwear for men and women; when this substance is used in undergarments, these garments can be designed on the small side with full knowledge that they will fit to expand the user's physique when they are worn. WebbCompared to polyether polyols in polyurethane elastomers, polyesters offer higher physical properties, cut, tear and wear resistance, better sliding abrasion and flex fatigue resistance. They are tough and durable. Polyester polyols in a polyurethane also exhibit very good resistance to oil, grease, fuels and nonpolar solvents.
