Schematic structures of thermoplastics and crosslinked rubbers

Among the numerous acronyms relating to thermoplastic elastomers, let us quote without claiming to be exhaustive  

TPEE or COPE ThermoPlastic Ester Elastomer or CO-PolyEster SBC Styrenic Block Copolymer 

PP/EPDM-V Vulcanized EPDM dispersed in polypropylene PP/NBR-V Vulcanized nitrile rubber dispersed in polypropylene PP/IIR-V Vulcanized butyl rubber dispersed in polypropylene 

PP/EPDM Unvulcanized EPDM blended with polypropylene or block copoly- 

When one wants to replace crosslinked elastomers by TPEs, it is necessary to survey the problem with a fresh eye and to redesign the subset where the part is used and redraw it to reduce the strains and integrate a maximum of functions to reduce the end-cost.
