摘要: A curable epoxy resin composition is provided. The composition includes at least one diglycidyl ether of bisphenol A (DGEBA) and at least one diglycidyl ether of bisphenol F (DGEBF) as epoxy resins, in which the weight ratio of DGEBA:DGEBF is within the range of about 15:85 to 45:55; (ii) an anhydride hardener; (iii) and at least one plasticizer. The composition can additionally include a catalyst, at least one filler material and/or further additives. The dynamic complex viscosity value (η*) of the composition is within the range of 0.1 to 20 Pa·s. The present disclosure also provides a process for making the composition and electrical articles including an electrical insulation system made from the composition.
