Russ Phifer's response is excellent.
I would add that the expiration date, while often largely arbitrary, is the date after which the manufacturer or supplier is going to reject any legal responsibility connected with use or misuse of the material. So if your use is ever likely to be assessed or discussed in a legal or adversarial situation, you probably do NOT want to use anything beyond the expiration date - unless, perhaps, you have comprehensive testing results showing that the item is not impacted by age deterioration at the time you are using it.
