Carbon Black Content Tester for Polyethylene Tanks

Tube furnace unit that determines the carbon black content in black or UV-stabilised polyethylene by pyrolysis and weighing. Used by tank makers to confirm UV protection level.

Specification

A weighed polymer sample is heated in a nitrogen stream at 550 deg C so the polymer decomposes while the black remains, and the residue is weighed. The result, typically 2.0 to 2.5 percent, confirms that the compound gives adequate UV protection for outdoor tanks. The furnace has stable temperature with programmed ramp.
