Determination of the thermal stability of PVC
In 1999 Metrohm introduced the Thermomat, a dedicated instrument for determining the thermal stability of PVC and PVC products, a well approved method for PVC Quality Control
Two heating blocks allow analysis of eight samples at one or two different temperatures.
Up to four PVC Thermomats can be connected to a PC and operated simultaneously with the included software.
Optimum flexibility is achieved by individual management of each sample and heating block.
With the disposable sample reaction vessels the cleaning procedure is reduced to a minimum.
The method of determination depends upon the fact that chlorinated plastics decompose at elevated temperatures with the release of gaseous HCl.
These thermal decomposition products are blown off by a stream of inert nitrogen into the measuring cell, filled with distilled water.
The thermal stability of the PVC materials is determined by measuring the conductivity in the measuring cell. Request a free brochure from Metrohm UK ...
