Semitron™ ESd HPV PEEK electrostatic 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. Semitron™ ESd HPV PEEK is ideal for chip trays and carriers, PCB board manufacturing and fixturing for electronic assemblies.
