Poly ether ether ketone (PEEK) is a kind of polymer which contains one ketone bond and two ether bonds in the main chain. It is a special polymer material. It is a kind of semi crystalline polymer material with melting point of 343 ℃, Tg = 143 ℃, thermal deformation temperature of load as high as 315 ℃ and instantaneous service temperature of 300 ℃. The results show that the tensile strength is 132 ~ 148 MPa, the density is 1.265 (amorphous) ~ 1.320 (crystalline) g / cm3; the maximum crystallinity is 48%, usually 20 ~ 30%, impact strength (notch) 60 ~ 80J / M; elongation at break ≥ 150%; water absorption ≤ 0.1%; volume resistivity 1016 Ω· cm; bending strength ≥ 140MPa; dielectric constant 3.2 ~ 3.3; tensile strength ≥ 93mpa; flame retardant (UL94) It can be used as high temperature resistant structural materials and electrical insulation materials, and can be used as reinforced materials with glass fiber or carbon fiber. This material has a large number of applications in aerospace, medical devices (as artificial bone repair of bone defects) and industrial fields, known as the pyramid tip of the plastic industry.
