Premix Thermoplastics PRE-ELEC® PP 1398 Conductive Thermoplastic Compound
Categories: Polymer; Thermoplastic; Polypropylene (PP); Polypropylene with Carbon Black Filler

Material Notes: PRE-ELEC® PP 1398 is a conductive thermoplastic compound based on polypropylene. Conductivity is achieved by using special conductive carbon black. In addition to a low electrical resistivity PRE-ELEC® PP 1398 has an excellent balance of mechanical properties and is easy to injection mould.

Applications: Include injection moulded crates, boxes, pallets and tote bins for electronic components and other static sensitive devides (SSD).

Processing: PRE-ELEC® PP 1398 compound can be processed in the injection moulding machines using normal processing conditions as with polypropylene.
Test Specimen: 10[mm] wide moulded rod
