Which material is pvc and pu good? How to distinguish the fabric of the bag is pu or pvc? Coated fabric is a fabric that has been treated with a special process to form a uniform covering rubber on the surface of the fabric, which makes the fabric more waterproof and windproof. The market bag fabrics are leather, canvas, oxford, PA coating, PU coating, PVC coating, PE coating, EVA, etc. So, how to distinguish the fabric of the bag is pu or pvc? Xiaobian introduced to everyone.


The PU polyurethane coating in the bag is made of PU white glue coating and PU silver glue coating. The basic properties of PU white glue and silver glue coating are similar to those of PA coating, but PU white glue and silver glue coating are more full, fabric is more elastic, and the fastness is better, and PU silver glue coating can withstand high water pressure. And the PU coating has moisture permeability, ventilation, abrasion resistance, etc., but the cost is high and the weather resistance is poor.


Compared with the PU coating, the PVC coated bottom fabric is thinner and cheaper, but the PVC coated film is not only toxic, but also easy to age. More importantly, the PVC coating feels no PU coating. And the fabric is still relatively hard, if the fire is used, the taste of the PVC coated fabric is much larger than that of the PU coated fabric.


The PU and PVC coated fabrics in the bag have the difference of hand feeling and taste. Another point is that the PU coating is generally leather and the PVC is glue.
