AP-60 polymer is for sealing in high-pressure, high-temperature settings that also require high resistance to wear and friction. The material is a fully fluorinated, chemically modified fluropolymer alloy of Alkoxy-TFE with a fraction of polybenzmidazole as a polymer matrix. It is reinforced with organo-metallic microspheres and high-purity graphite fibers. The polymer seals at 650F and 2,500 psi, with intermittent high-temperature excursions.
