Flexible PVC vinyl film, is made from raw material PVC resin and plasticizer.PVC resin is a white or light yellow powder ,density of 1.35-1.45g/cm3, which one is flame retardant. The plasticizers make the flexible PVC film soft and good performance low temperature resistance.
However, the addition of plasticizers in the flexible PVC film production, reduce the flame retardant performance. To improve the flame retardant, it is necessary to choose flame retardant plasticizers such as phosphate esters and chlorinated paraffins in flame retardant PVC film calandering production. The order of the flame retardancy of plasticizer is: TCP>TPP>TOP>DPOP.
