“…Studies have been reported on foaming of polymeric materials (neat polymers, blends, and nanocomposites) based on different types of block copolymer TPEs, namely, styrenic block copolymers, [ 33,105,106 ] poly(ethylene‐ co ‐octene) (PEOc), [ 93,107 ] thermoplastic polyurethane (TPUs), [ 108,109 ] poly(ether‐block‐amide) (PEBA), [ 4,110 ] and thermoplastic polyester elastomer (TPEE). [ 111,112 ] Various research groups have conducted foaming of different thermoplastic polyolefins (TPOs) (blends of thermoplastics and elastomers in which there is no vulcanization of rubber) [ 15,113,114 ] and thermoplastic vulcanizate (TPVs) (blends of thermoplastics and elastomers in which the elastomer is dynamically vulcanized).
