What are the advantages of bisphenol A epoxy resin?
Bisphenol A BPA epoxy resin is the most produced and widely used type of epoxy resin. It exhibits high transparency and is synthesized from bisphenol A BPA and epichlorohydrin in the presence of sodium hydroxide. The degree of polymerization, denoted as "n", typically ranges from 0 to 25.Based on molecular weight, epoxy resins can be classified into various grades. Generally, low molecular weight epoxy resins have an average "n" value of less than 2 and a softening point below 50°C, and are referred to as soft epoxy resins. Medium molecular weight resins have an "n" value between 2 and 5, with a softening point ranging from 50°C to 95°C. Resins with an "n" value greater than 5 (softening point above 100°C) are classified as high molecular weight resins.
