Property

Due to high technical barriers and limited sources of raw materials, global BDO production is relatively concentrated. In 2011, global BDO capacity was mainly distributed in Asia, the United States and Europe, with Asian BDO capacity accounting for 56.6%.

1,4-butanediol (BDO) is an important organic chemical and fine chemical raw material, which can generate many derivatives such as THF, PTMEG, GBL, etc. BDO and its derivatives can be widely used in PBT plastics, spandex, polyurethane, pharmaceuticals, cosmetics and other fields.
