DAP (Diallyl Phthalate)
Diallyl-Phthalate (DAP) has long been the material of choice for critical, high-performance military and commercial electrical components where long-term reliability is demanded.

The uniqueness of Sumitomo Bakelite North America DAP molding compounds lies in the chemistry of the resin system, which enables the parts molded from these compounds to retain their superior insulating properties, even when subjected to extreme environmental conditions of high heat and high humidity over long time periods. Additionally, DAP compounds will resist dimensional change in high-heat soldering environments where competitive materials may warp.
