Lamp Black

The lamp black process is the oldest industrial process of pigment manufacturing. The heating is conducted on a cast-iron pan with the feedstock. Radiant heat from the hood causes the feedstock to vaporize and partially combust. Most of it is converted into carbon black.

Typical characteristics for lamp black are low surface in combination with substantial structure (aggregation of particles) and a broad particle distribution. Typical particle sizes are between 60 nm and 200 nm.

This kind of carbon black is used in paint, plastics and several special applications. It provides good dispersability due to a high structure and unique coloristic values like bluish undertone.

In rubber and EPDM compounds lamp black offers very unique properties due to the combination of bigger particles and low surface areas. Our lamp black can be provided in fluffy and beaded form.

In comparisment with the furnance carbon black process the lamp black process does not permit much modifications in primary particle size, surface and structure. Nevertheless the typical lamp black process leaves a unique fingerprint to the carbon black properties.
