PVC burning performance
- Jun 22, 2018 -

PVC's burning performance is not good, away from the fire that is off, the flame is yellow, the lower end is green, white smoke, is a non-flammable plastic; burning, there is irritating smell of hydrogen chloride released, softened when burned.

In practice, since PVC contains a large amount of organic esters (such as DOP) flammable plasticizers, flame retardance issues must be considered. The use of antimony trioxide in PVC alone has flame retardancy. If used in combination with chlorinated paraffin, the flame retardancy is better. Transparent PVC should use phosphate flame retardant, commonly used tricresyl phosphate (TCP) but TCP low temperature performance. Halogenated phosphate esters are good, but the price is a bit expensive
