2.Product Description:
1, 4-BDO is a versatile chemical intermediate because of its terminal, primary hydroxyl groups and its hydrophobic and chemical resistant nature. Polymers produced upon reaction with diacids or diisocyanates are the basis for many commercial polyurethane and polyester applications.
1, 4-BDO is used to manufacture polybutylene terephthalate (PBT). PBT& acute;s high strength, excellent thermal stability and good durability lead to its many uses in the automotive, electrical and appliance industries. PBT is also compatible with several other thermoplastics with several other thermoplastics which enables a compounder to tailor a polymer alloy to an end user& acute;s specifications.
1, 4-BDO is a key component of thermoplastic copolyester elastomers. These elastomers rely upon 1, 4-BDO to provide crystallinity which in turn provides elasticity and resilience to these terephthalate based polyesters.
