Automatic determination of PVC thermal stability
With the 763 PVC Thermomat Metrohm offers the first fully PC-controlled instrument for the determination of the thermal stability of PVC plastics
In 1999 Metrohm introduced the Thermomat which is a dedicated instrument for determining the thermal stability of PVC and PVC products.
Thermal stability is a well approved method for the Quality Control of PVC and its products.
When a sample is exposed to elevated temperatures HCl gas is formed due to the thermal decomposition of the resin.
The time after which the HCl can be detected is the evaluation criterion.
The 763 PVC Thermomat uses conductivity for this detection.
Pure PVC resin cannot be used for manufacturing; it is always mixed (blended) with additives improving stability (stabilisers) and plasticity (plasticisers).
Pure PVC shows very short induction and stability times, and if additives are added, these times significantly increase.
The Thermomat enables compliance to International standards DIN 53381 Part 1; DIN VDE 0472 part 614; ISO 182-3 Parts 1,2 3 and 4. Request a free brochure from Metrohm UK ...
