Product Description

Product Description

 

1, 3-propanediol (1, 3-propanediol, 1, 3-PDO) is a colorless, odorless, salty, hygroscopic viscous liquid. It is a raw material for the production of unsaturated polyester, plasticizer, surfactant, emulsifier and demulsifier. In the polyurethane industry, it is commonly used as the raw material of polyester polyol, the initiator of polyether polyol and the chain extender of polyurethane. In the organic chemical industry, it is also an important monomer and intermediate, the most important use is as a polymer monomer, the synthesis of polypropylene glycol terephthalate.
