Bamberger claimed that one of his students, Hindermann, had noted the formation of polyethylene in 1897. In addition to main polyethylene types (LDPE, HDPE), medium-density polyethylene (MDPE), cross-linked polyethylene (PE-X) and ultra-high-molecular-weight polyethylene (UHMWPE) are also used for industrial purposes.
