Does anybody know why Motorcycle helmet manufactures recommend replacing helmets every 5- years regardless if they have bounced off the pavement or not? I know that when EPS (Expanded Polystyrene), the protective lining in DOT approved helmets, is impacted that it crushes and does not flex back so it definately should be replaced. Does time also have a degrading effect on EPS? EPS is the material used to make coolers and coffee cups. I am under the impressing that it takes a radioactive particle half-life (or maybe never) for EPS to degrade in a landfill. Will good care and storage of a helmet make it last longer?
