Influence of filler dosage of PVC cable material on flame retardant performance
May 17, 2018

In the PVC cable material, usually need to add a certain amount of filler. If we add talc and clay as fillers, the oxygen index can be increased 1 to twice times, but the burning speed of the cable will be doubled, the maximum dimming coefficient unchanged. If the addition of Al (OH) 3 as a filler, the combustion rate increased by 50%, the oxygen index increased, the maximum reduction coefficient decreased, so it has a good effect on the smoke emission inhibition. CA CO3 Fillers are also usually added to the PVC, scientists have found that [5], with the increase in CA CO3, the oxygen index of PVC cable decreased, and the maximum reduction coefficient also decreased, so the amount of CA CO3 can not be too much, otherwise it will affect the flame retardant smoke suppression effect of cable materials. However, CA CO3 can be used as a trapping agent for HCL Gas, which has a very significant effect.
