Physicochemical Properties:
E type epoxy resin is widely used in China. It is made from bisphenol A and epichlorohydrin. According to the manufacturing method, there are 3 types of resin: small molecule resin, molecular weight is 340-700, its softening point < 50 °C and liquid in normal temp. ; middle molecule resin, molecule weight is 800-2200, its softening point is 50~ 95 °C, and it is solid in normal temp. ; high molecular resin, molecular weight is 2200, its softening point > 100 °C, and it is solid in normal temp. Customers can choose different type according their requirements.
