Well, use pvc foam board for flooring is not an easy thing, and it is my bold test, I know many pvc foam board from China is not lead-free, many are toxic, so what i need to do first is test the pvc boards first, I found 5 manufactorer in China and asked them send me samples, I sent my samples to FDA, only epvcmaker passed the test, they promised lead-free, non-toxic, and they did do it. I choose pvc foam board is becase pvc foam board is stronger, and water-proof, easy cleaning, what i know is it is more longer than wood. you-epvcmaker.com do help me a lot, and I will bring you more customers.
