Mechanical properties for HDPE foam Mechanical properties for HDPE foam cjmorse (Mechanical) (OP) 31 Mar 14 15:37 I'm looking for UTS and or Young's Modulus for an HDPE structural foam. Anyone have any ideas? RE: Mechanical properties for HDPE foam Pud (Mechanical) 31 Mar 14 15:43 Must depend on foam density, surely? Data from manufacturers for a specific product is probably your best bet. H www.tynevalleyplastics.co.uk It's ok to soar like an eagle, but weasels don't get sucked into jet engines. RE: Mechanical properties for HDPE foam cjmorse (Mechanical) (OP) 31 Mar 14 16:25 True on both counts, however, the vendor has been slow to respond. I'm hoping I can find some general information at some standard density. I have seen information for Polyurethane foams at 20% reduction in density.
