Hdpe minimum bend radius
WebCreated Date: 2/5/2004 5:55:42 PM Websafer minimum bending radius = four times the thickness of the sheet. m.b.r. = T (100-E)/ (2E), where T is the thickness and E is the % elongation at break. For example, suppose a sheet is 5 mm thick and its ductile strength permits 25% elongation before breaking. Then the minimum bend radius is about 5 (100-25)/ (2*25) = 7.5 mm.
