Product Description:

Hydrogenated bisphenol A (HBPA), also known as 4,4′-(Propane-2,2-diyl)dicyclohexanol, is the hydrogenated derivative of bisphenol A. It typically appears as a white to off-white crystalline powder or flakes. HBPA is valued for its enhanced thermal stability, improved weatherability, and superior UV resistance compared to conventional bisphenol A. These properties make it a crucial intermediate in the production of high-performance polymers, particularly epoxy resins, polyester resins, and specialized coatings, where durability and color stability are paramount.
