摘要:
A method of making personal protective equipment, such as a push- in earplug, is disclosed. The method includes the steps of covering a substrate (310) with an outer layer (330) that includes an unactivated foaming agent, positioning at least a portion of the outer layer in a mold (370), and activating the foaming agent such that a portion of the outer layer expands.
