Inorganic Flame Retardant and Smoke Suppressant in Flexible PVC

Adding the inorganic flame retardant and smoke suppressant to the flexible PVC is a very popular method to enhance the flame-retardant property.This method has the characteristics of convenience,high efficiency and lower price.It has become the main method in improving the properties of soft PVC materials.In this paper,several different flame retardant and smoke suppressants have been compared.Based on the comparison,the flexible PVC should be developed into high efficiency,low poison,anti-climate,and lasting flame retardant.
