What are the insulating materials used for military aviation plugs?

I. What are the insulating materials for military aviation plugs? Aviation plug insulation materials can be divided into thermosetting plastics and thermoplastics, thermosetting plastics are phenolic resins, poly(diallyl phthalate), epoxy resins and unsaturated polyester; thermoplastics are mainly glass fiber reinforced pET, PBT, FCT, PAB, PA66, PA6T, PA9T, PA6T, PA9T, poly(propylene glycol) terephthalate, polyetherimide, polyethersulfone, polyarylate, polyaromatic ether, and so on, Polyarylene ether, etc. If it is a low-frequency aviation plug, the materials used in the past are mostly mineral-filled phenolic plastics, but the production efficiency is low, so it has been replaced by new thermoplastics such as PA, PC, reinforced PC and polyalum; if it is used in hot and humid conditions, it can be made of DAP materials; if the application has high requirements for sealing, it can be made of sulfur-free or low-sulfur rubber with good dielectric properties. Only according to the different requirements of different occasions to choose the right insulation plastic materials to fundamentally ensure the reliability of the aviation plug.
