As a class of high-temperature/performance polymer, Phthalonitrile (PN) resins have many excellent properties such as high thermal and oxidative stability, flame retardance, water, and chemical resistance. These properties make the PN resins attractive for many advanced technological applications, such as composite matrices, adhesives, and electrical conductors.
Phthalonitrile resins offer a better alternative to high-temperature polyimides and provide a high glass transition temperature and ease in property tailoring through molecular design without the evolved volatiles and complex cure cycles of polyimides. Phthalonitrile exhibits superior physical properties relative to other high-temperature polymers such as polyimides, BMIs and Cyanate Esters.

Phthalonitrile resins have an indefinite shelf life at room temperature.
Does not sustain combustion on exposure to flame.
Can be processed in the same way as ordinary commercial epoxy resins, using standard industrial composite manufacturing methods.
The Material chemistry can be tailored to melt at temperatures between 160 °C - 240 °C and control its initial cure to the required shape below 200 °C.
