The Differential Scanning Calorimetry
We would like to draw your attention regarding a new Rollepaal technique: the Differential Scanning Calorimetry (DSC) for the materials research.
There are multiple techniques for determining the quality of PVC parts, the most common being the acetone immersion test and the dichloromethane test. These aggressive chemical methods require that the degree of chemical attack be observed over a certain period of time, and they only provide a pass/fail result. A much more accurate and quantitative technique uses differential scanning calorimetry (DSC) to evaluate the quality of small samples PVC. For a given part, the DSC method accurately determines both the percentage of gelled material (called the degree of gelation) and the processing temperature at the precise location tested.
DSC technique to determine degree of Gelation of un-plasticized PVC (UPVC) on a regular basis for the PVC pipe industry.
In addition to the above mentioned application, Rollepaal also offers the following
- Determination of glass transition temperature (Tg)and crystalline melting temperature ( Tm) of different types of polymers.
- Determination of accurate melting points (till 250 deg C) of the different additives used in polymer and food industry
Analysis of the samples can be done quickly (within two weeks), thus less waiting time.
