Carbon Black is one of the most important filler in plastics materials. It not only acts as pigment but also as an UV absorber. However, the level of addition of this filler influences the plastics behavior a lot and hence, requires to be well controlled. This is major reason of determining the percentage of it in given polymer mass.

This test method is used to determine the average carbon black content in materials like plastic pipes, films, sheets, cables, water tanks. The test is often used as a quality control measurement for black polyolefin. This is particularly more effective in polyolefin and polyethylene.

Salient features:
  • Heavy & thick heat insulation providing to eliminate radiation of heat
  • Attractive powder coated body.
  • Using microprocessor based temperature controller
  • Providing m/c leveling arrangement for flow level of gas.
  • All glassware accessories are of "BOROSIL" make.
  • Nitrogen gas cylinder has to be arranged by the operator. (It will not be supplied with the instrument)
Brief Construction Details:
  • EIE Carbon Black Content Apparatus consists of a tubular furnace fabricated using mild steel.
  • Exterior body is powder coated in attractive shades.
  • The temperature of the furnace can be adjusted from ambient to 950° C working temperature.
  • Relatively low operating wattage of the heater ensures that the furnace life span is much better.
  • The heaters are made from best quality alloys to avoid premature fusions.
  • The temperature is controlled by Programmable (8 or 16 channels) Digital PID Temperature Indicator cum Controller with built in rate-of-rise device function to practically avoid any over-shoots and under-shoots & to offer better  temperature stability.
  • The EIE Carbon Black Content Apparatus is equipped with a nitrogen flow meter (Rotameter) and a full set of glass parts.
  • Rotameter is adjusted such that it will provide the nitrogen flow rate of 1.7 ± 0.3 Liters/Min only as per the test requirements.
  • Complete instrument will be supplied with wooden supporting back rack with clamp attachment to hold  the glass parts firmly during the experiment.
  • The glassware are of standard BOROSIL make.
