The utilization of fillers and reinforcements to develop an optimal DAP (diallyl phthalate) molding compound
- EG and G Mound Applied Technologies, Miamisburg, OH (USA)
Diallyl phthalate (DAP) resin-based compounds were formulated and tested. In these formulations, various types of fillers and fiberglass reinforcements were used in different concentrations while taking into consideration packing concepts, optimum aspect (L/D) ratios, resin content, rheology of the molding compound, and ultimately, the compound's performance. These formulations were required for transfer molding without restricting the melt flow through a gate size of less than 1 mm. The end products are very small parts that must conform to stringent dimensional tolerances (typically {plus minus}0.05 mm) and exhibit physical properties that exceed the requirements specified by MIL-M-14G without compromising excellent electrical characteristics. These objectives were achieved by changing from chopped glass roving to screened, milled fiberglass, by the use of microspherical fillers, and by improving micro packing which allowed an increase in the total
