SINOMER® BPFL (Bisphenol Fluorene, CAS 3236-71-3) is a high-purity, bulky bisphenol 单体 containing a rigid fluorene skeleton. It serves as a versatile building block for the synthesis of high-performance polymers, including polycarbonates, epoxy resins, polyurethanes, and polyesters. The rigid fluorene unit imparts excellent thermal stability, high glass transition temperature (Tg), and superior optical clarity to the resulting polymers. SINOMER® BPFL is especially valued in applications requiring high refractive index and low birefringence.
