Mitsubishi Chemical Advanced Materials Semitron® HPV ESd PEEK Polyetheretherketone
Categories: Polymer; Thermoplastic; Polyketone; Polyetheretherketone (PEEK); Polyetheretherketone, PEEK, Unreinforced

Material Notes: Semitron® HPV ESd Polyetheretherketone PEEK electro static dissipative shapes contain specific additives that make it an excellent performer in wear and friction applications where antistatic properties are essential. Due to this, this grade excels in electronic fixture applications that require a high degree of dimensional stability over an extended thermal range, as well as precise machinability.
