PV100 polymer self-adhesive film waterproof membrane
PV100 is a domestic product model that was originally called GRACE and is now called Kishibo.
It is a polymer self-adhesive film formed of synthetic polymer sheet (usually high-density polyethylene) as the base film, coated with hot-melt pressure-sensitive adhesive on the upper surface, and then sprayed with reactive bonding sand. waterproof materials.
Grace Company invented this material and the corresponding pre-paved anti-adhesion construction method.
At present, there are many such materials (polymer self-adhesive film waterproofing membranes) in China. It has been a huge profit in the past few years. As more and more waterproof companies in the market start to do it, the price is getting lower and lower. More and more rational, but still much higher than sbs coil.
The industry believes that it is the real polymer self-adhesive film that uses polymer hot-melt pressure-sensitive adhesives, but products made of modified asphalt rubber are also available on the market. Do not use modified asphalt, otherwise there are endless problems.
Simply saying that PV100 is Grace product, is the only one, but many manufacturers of polymer self-adhesive film products.
