The flame-retardant properties of cured epoxy resins were examined by measuring the LOI. To demonstrate the flame-retardant properties of DOPO epoxy resin, DOPO epoxy, and Bis-A epoxy were cured with (1) Ph Nov, (2) DDS, and (3) DICY for comparison. The LOI values are shown in Table III. Increased char formation can limit the production of combustible carbon-containing gases, decrease the exothermicity due to pyrolysis reactions, as well as decrease the thermal conductivity of the surface of a burning material.24 DOPO epoxy cured with Ph Nov, DDS, and DICY had LOI values of 34, 32, and 36 that were higher than those of Bis-A epoxy cured with Ph Nov, DDS, and DICY (LOI 5 26, 22, 21). The UL- 94Vtest determines the upward-burning characteristics of a solid. Five sample bars of each cured epoxy resins suspended vertically over surgical cotton were ignited by a Bunsen burner; two ignitions of 10 s each were applied to the sample. The results of UL-94V and LOI test are listed in Table III. DOPO epoxy resin, besides being superior to phosphorus-free epoxy resin in flame retardancy, also generated much less visible smoke than phosphorus-free epoxy resin.
Dynamic Viscoelastic and Thermal Properties of Flame-Retardant Epoxy Encapsulants
Owing to excellent heat, solvent and chemicalresistance, good adhesion and inexpensiveness, epoxy resin has been widely employed in the encapsulation of microelectronic devices. In this study, DOPO epoxy and TBBA epoxy (tetrabromobisphenol A epoxy resin) were compared for their flame retardancy in the encapsulation formulation . Bis-A epoxy was blended with various amount of DOPO epoxy and then cured with Ph Nov to give the cured products with phosphorus content of 0, 0.58, 1.03, and 1.45% (Bis-A/Ph Nov, DOPO-A, DOPO-B, DOPO-C). In the same manner, Bis-A epoxy was blended with TBBA epoxy and then cured with Ph Nov to give the cured products with bromine content of 4.01, 7.24, and 9.91% (TBBA-A, TBBA-B, TBBA-C). Thermal properties of cured epoxy resins are shown in Table IV. It should be noted that Tg of cured epoxy resins increased with the increase in phosphorus content while Tg decreased with the increase in bromine content . The result may be attributed to the bulky rigid phosphorus-containing group.
