The process of enumerating the development of special epoxy resins and hardeners as examples, epoxy-cured resins with low dielectric constant is described in the chapter. Many excellent characteristics of epoxy resin originate from hydroxyl groups generated on curing. To lower the dielectric constant,...
The dielectric properties of an unmodified epoxy resin with a wide range of hardener content were investigated over the frequency range 5 cycles/sec. to 50 Mcycles/sec and over the temperature range 12–95°C. In the frequency region below 1 Kcycle/sec., the loss is predominently high ...

cured epoxy resin has excellent heat resistance, dielectric constant; curable blends containing polyphenylene ether and polystyrene thermoplastic elastomer; curable films; fast curing; used for electrical devices; varnishes solvent solubility; conductor layer...
Addition of epoxy resin concentration,hydrothermal aging and ultraviolet radiation aging caused increase of the dielectric constant and dielectric loss. However, the modified system belongs to excellent dielectric material, with epoxy resin concentration below 30wt%. 展开 关键词: cyanate ester resin epoxy...
A method for preparing a low dielectric constant epoxy resin composition, the first raw material preparation: Epoxy 70 - 100 parts, 1-10 parts of a curing agent, 50 to 70 parts solvent, and then dissolved with a solvent epoxy resin dissolved with stirring at room temperature for 1-2 hours...
Epoxy/BaTiO3 composite embedded capacitor films(ECFs) were newly designed for high dielectric constant andlow-tolerance (less than 5%) embedded capacitor fabricationfor organic substrates. In terms of material formulation, ECFsare composed of a specially formulated epoxy resin and latentcuring agent, an...
