General - Aavid Thermalloy component material composition

What material is DAP? I’m looking at Aavid Thermalloy part number 7717-156DAPG-ND, and I want to know what type of material it is?

DAP stands for Diallyl Phthalate. DAP is a polymer resin that has long been the material of choice for critical, high-performance military and commercial electrical components where long-term reliability is demanded.
