Inquiry (采购产品): safety glass for mines Good Morning, Please inform by return the best price and the shortest possible delivery for the following goods : - bullet proof sight glasses dia 140 mm, thickness 30 mm ( consist of six layers 4 mm each), working pressure 15 bar, must withstand hit by 1 kg weight falling from 1 meter height , quantity 5 pcs for trial , total quantity 100 pcs of one size per year. The best would be if after dropping 1kg weight from 1 meter there is no crack at all. However the crack is permissible but after this test with the weight the glass must withstand 15 bar of water pressure. My clients are interested to get the product from the best material used in cool-mining. May be kevlar glass instead of bullet proof glass ?
