Inquiry (采购产品): polypropylene fabrics Seeking a little more info on polypropylene sack cloth (PSC). We're volunteer "engineers without borders" to help in shelter reconstruction in the tsunami region. We have a process of using standard fiberglass screen, several layers, as reinforcement for acrylic-modified cement panels - for walls and roofs. But would like to utilize the plentiful PSC instead. Have tested the PSC for adequate strength and resistance to moisture and heat. Our questions now are: (a) it's chemical resistance to the alkalinity of portland cement? (b) is PSC also found with coarser weave than typical tight closed surface, having 6 - 10 apertures per inch? **** Hidden Message ***** George Nez 2570 S.
