Lanzhou Institute of physics and chemistry, Chinese Academy of Sciences launched new polyester polyol technology

August 7, 2006

recently, Lanzhou Institute of physics and chemistry, Chinese Academy of Sciences launched a new technology for the production of polyester polyols, most of which are all technologies of a large flexible packaging manufacturer who does not want to be named publicly. This technology can be used to chemically treat mineral water bottles, beverage bottles, edible oil barrels, waste materials from polyester factories, corners and corners of polyester products with small weight loss, waste materials and other materials discarded in industry and life under the action of organic alcohol chemicals and catalysts to produce polyester polyols, which can be used to produce polyurethane foaming materials and intermediates of synthetic materials such as plastics, rubber, coatings, adhesives and so on

compared with polyether polyols, which are widely used in the market at present, polyester polyols have advantages in temperature resistance, wear resistance, oil resistance and mechanical strength. Therefore, polyester polyols have been developed by showing their characteristics in polyurethane foaming materials, polyurethane fibers, coatings, adhesives, elastomers and other products around synthetic leather cores. Especially in recent years, a certain proportion of polyester polyol is added to the polyether type polyurethane rigid foam materials, which can greatly improve the strength of the materials and significantly reduce the production cost of polyurethane rigid foam materials; Due to its low thermal conductivity and excellent thermal insulation performance, polyester foamed materials are widely used in pipeline insulation and building insulation at the 2014 exhibition
