WebFLAMMABILITY DIAGRAM The flammability triangle can serve as an immensely useful resource to plan safe cargo operations on board a ship, but merely seeing the flammability chart isnt sufficient unless you are able to decipher what the various lines on the graph mean. Learn more about it in this article. Introduction WebThe second graph stage is a graph of wear resistance versus flammability. As it is already pointed out in the first stage, the materials have to have good wear resistance and very poor flammability. Therefore, the second graph stage limits 6 materials out of 67 materials available. And, they are Butyl Rubber, EVA, Isoprene (IR), Natural Rubber
