Polyethylene glycol, one of the chemical components in Polyether block amide serves what purpose?
Polyether block amide Polyether block amide or PEBA is a thermoplastic elastomer (TPE). It is known under the tradename of VESTAMID® E (Evonik Industries), and PEBAX (Arkema). It is a block copolymer obtained by polycondensation of a carboxylic acid polyamide (PA6, PA11, PA12) with an alcohol termination polyether (Polytetramethylene glycol PTMG), PEG). The general chemical structure is:
Polyethylene glycol propylene glycol cocoates Polyethylene glycol propylene glycol cocoates or PEG propylene glycol cocoates are chemical compounds produced by the esterification of polyoxyalkyl alcohols with lauric acid. Their chemical designation is PEG-8, referring to its polyethylene glycol (PEG) molecular chain length.
