The TVOC results show that burning depends very much on the threshold concentration of volatiles as discussed earlier and the results show that values should be lower than the virgin material if the material need to pass the V0 classification. As we can observe here that the TVOC values differ for PFR 1 and PFR 2. The results show that by performing such measurements for a large number of samples, it must be possible to determine specific threshold values for V0 classifications for different types of PFR additives and different HFFR formulations because according to our earlier discussions TVOC, heat of combustion, ignition temperature and the flame-retardant properties are interrelated to each other. This measuring technique has been fine-tuned further to obtain results with narrow spreading. It is evident from the results that addition of Paxymer® to PFR additives favors also to reduce the TVOC values in addition to the increase of ignition temperature at reduced addition levels of PFR and thereby showing its function as an effective synergist.
