3. Applications of PRINTEX kappa 70:
Polymers, General Conductive Applications, Wire & Cable
4. Forms of Supply of PRINTEX kappa 70:
Beads, available in FIBC 2 x 450 kg doublestack or 700 kg and 15 kg paper bag on a 600 kg pallet.
5. Storage Conditions of PRINTEX kappa 70:
The high surface area of Specialty Carbon Blacks bears the inherent risk of adsorption of vapors and/or gases, which in turn impacts the product’s application relevant properties.
It is therefore recommended to always store Specialty Carbon Blacks out of reach of potential contaminants and sources of contamination.
Storage temperatures of PRINTEX kappa 70 should not exceed 50 °C.
PRINTEX kappa 70 should be stored under cool and dry conditions.
Please refer to our Product Safety Data Sheet.
Densification or adsorption processes etc. may adversely affect the product’s application relevant properties.
This also applies to storage in silos or other closed containers.

PRINTEX kappa 70 for conductive Plastics Applications:
PRINTEX kappa 70 provides superior conductivity already at lower concentration than most of previously listed Carbon Black in the field of conductive blacks.
This improved percolation threshold is now closing the gap between Black XPB 538 and other regular Conductive Black such as HIBLACK 40B2.
At the same time the infl uence on rheology and mechanical properties of final parts was maintained on an excellently well-balanced level.
During the phase of PRINTEX kappa 70 product development specifi c attention was turned on good processability since necessary pigment loading at desired high output rates often delimits effi cient yield production.
All in all we release a high conductive Carbon Black with outstanding conductive overall performance.
Typical field Examples for end use of PRINTEX kappa 70:
Spark discharge flammability, e.g. Gas Pump Nozzle
Explosion-proof Areas, e.g. ATEX
Antistatic Packaging Films
Electrical Grounding and antistatic Flooring
LEDs in conductive Carrier Tray
Transport Boards for electronically sensitive Devices
Applications aimed for:
PRINTEX kappa 70 is qualified as an universal conductive pigment performing excellent in almost all regular electrically conductive plastic compounds and conductive applications.
PRINTEX kappa 70 can be used in most signifi cant polymer types such as polyolefi n, co-polymers, polyvinyl chloride, high-impact polystyrene, polyamide and others.
It is targeted for injection molded parts such as fuel canisters, boxes, housings for electrical goods, carrier trays of electronic devices, and is working just as well in extruded electrically conductive pipes, profi les, blown- and cast-fi lms.
Further target industries are areas with explosive risks, e.g. conductive hoses for the mining industry or ATEX environment (explosion protection), carpet backs and antistatic flooring and many articles for the automotive industry.
