A New Perspective on HCl Scavenging at High Temperatures for Reducing the Smoke Acidity of PVC Cables in Fires. II: Some Examples of Acid Scavengers at High Temperatures in the Condensed Phase

In the European Union, according to Regulation (EU) n. 305/11 (Construction Product Regulation, or CPR), cables permanently installed in buildings need additional classification for acidity, performing EN 60754-2. The research on PVC compounds with low smoke acidity helps to produce cables in the best additional classes for acidity, giving the PVC cables the possibility to be used in medium and high fire risk locations. In this paper, some acid scavengers at high temperatures are tested to verify their possible scavenging mechanism and their efficiency in performing EN 60754-2 at different temperatures.
