| PRE-ELEC® PP 1351 is a dissipative thermoplastic compound based on polypropylene. The electrical dissipation is achieved by using special conductive carbon black. In addition to stable surface resistance between 10e5-10e8 ohms. PRE-ELEC® PP 1351 has an excellent balance of mechanical properties and is easy to injection mould. Typical applications include injection moulded dissipative ESD products such as crates, boxes and tote bins.&& |
