Each electrical application has different requirements in regards to the conductivity level.
The amount and type of carbon black determines the conductivity of the product.
We offer 6 basic black grades with carbon Black:
PG 5412 bnc or PG 5415 bnc – Black non conductive
PG 5412 b or PG 5415 b – Black with antistatic properties: < 10^11 Ohm surface resistivity
PG 5412 bc or PG 5415 bc – Black conductive: < 10^6 Ohm surface resistivity
