What is the difference between ordinary and flame-retardant PVC?

What is difference between ordinary and flame-retardant PVC? First, you may need to know whether your own PVC products are hard or soft. Rigid PVC: Since polyvinyl is a hard-to-burn material, hard PVC is inherently flame-retardant, while soft PVC is different, because soft PVC needs to be added with oily plasticizer , Let the material soften, the flame retardant effect of the material will be weakened. Everyone knows that oily substances will burn in fire. At this time, if you want to make soft pvc achieve the flame retardant V0 effect, you need to add a flame retardant to the material. , Then the difference between ordinary and flame-retardant pvc is because of the flame retardant added by the latter, so the density and cost of flame-retardant pvc will slightly increase, while the transparency and tensile strength will be slightly reduced. Enhancement of combustion performance.

In other words, if the hardness of soft pvc is softer, then if you need to achieve better flame retardant effect, you need to add more flame retardants, then the cost will rise greatly, which is why some pvc prices are so expensive The reason is up.
