Origin of E-TPU：
The Expanded TPU（ETPU） cell foam raw materials was originally invented by BASF known as the Infinergy foam and Adidas was the first company who had applied it in its shoe mid-soles known as the Energy Boost. Previously only BASF owns the E-TPU cell foam bead raw material manufacturing technology, but after many years now the Chinese local chemical companies has already resolved the E-TPU cell foam bead raw material manufacturing technology.
