Thermoplastic chemical structure
WebbThermoplastic polyamide elastomer (TPE-A) is a newly developed class of alternating block copolymer elastomers. It consists of soft segments of polyesters or polyethers and a rigid block of polyamide. The polyamide can be for example polyesteramide (PEA), polyetheresteramide (PEEA), polycarbonate-esteramide (PCEA) or polyether-block-amide … WebbPolyamide 12 (PA12) or Nylon 12 is a semi-crystalline thermoplastic. It has a similar performance to Polyamide 11. It can be derived from both petroleum and renewable sources. It is an expensive polymer compared to other polyamides.
