Bisphenol A polyether polyol (BPA-based polyether polyol) is a kind of polyether compounds formed by polymerization of ethylene oxide, propylene oxide with bisphenol A as the core structure. It has both high strength and flexibility because its molecular structure contains rigid aromatic rings and flexible ether bonds. It is widely used in multiple industrial fields.

Properties:

1.       Excellent Mechanical Properties

The molecular structure containing aromatic rings that gives the material high rigidity and excellent mechanical properties.

The polyether chain segment provides a certain degree of flexibility, giving it high impact toughness.

2.   Heat resistance and thermal stability

      Bisphenol A polyether polyol has a high glass transition temperature (Tg) and thermal decomposition temperature, and it can be used in high temperature conditions.

3.   Chemical resistance

      It exhibits excellent resistance to chemicals such as acids, alkalis, and solvents, especially stable chemical properties at high temperatures.

4.   Good insulation properties

      Excellent electrical insulation properties, suitable for electronic and electrical applications.

5.   Processability and Adjustability

      The molecular weight and functional groups can be adjusted through the synthesis process to meet different application requirements. It can be modified into epoxy resin or polyurethane to improve the overall performance.

Application
