PEBA material is a block polymer prepared from polyether and polyamide blocks. The efficiency of tetra-alkoxide catalyst family discovered by Deleens made it possible to produce ultra-high molecular weight materials, which were put on the market under the Pebax trademark in 1981. Their unique properties are attributed to their unique phase separation structure. There is a hard phase, mainly including polyamide blocks, and a soft phase, mainly including polyether blocks.
