PRE-ELEC® PS 1340

About
PRE-ELEC® PS 1340 is a conductive thermoplastic concentrate based on polystyrene. Conductivity is achieved by using a high concentration of special conductive carbon black. PRE-ELEC® PS 1340 can be diluted up to 60% with virgin or recycled polystyrene. The actual amount should always be tested as it also depends on the processing conditions. Typical applications include mono- or co-extruded sheets for thermoformed trays.&&
