PRE-ELEC® PP 1381

About
PRE-ELEC® PP 1381 is a conductive thermoplastic compound based on polypropylene. Conductivity is achieved by using special conductive carbon black. PRE-ELEC® PP 1381 contains a high load of carbon black and it can be diluted up to 50% with virgin or recycled PP. The actual amount should always be tested as it also depends on the processing conditions. PRE-ELEC® PP 1381 is intended for injection moulded products. It is cost-effective solution for big mouldings e.g. boxes, crates and pallets.&&
