Polymers play a vital role in various technology sectors. They offer a range of properties in terms of mechanical strength and flexibility, electrical insulation, and thermal and chemical resistance. Two polymers of particular note are polyimide (PI) and polyethylene Terephthalate (PET). Polyimide, known for its high mechanical strength and thermal/chemical resistance, continues to be a mainstay in the flexible printed circuit board market, serving as a robust dielectric material to manage the flow of electrical current. In resin form, PI is also used in thermoset carbon fiber constructs as well as high-temperature fiber coatings and integrated circuit passivation layers.
