Le PEEK est un plastique haute performance reconnu dans l\u2019industrie<\/h1><\/div>

Le PEEK est un polym\u00e8re haute performance largement r\u00e9pandu. Il pr\u00e9sente des propri\u00e9t\u00e9s m\u00e9caniques et une r\u00e9sistance \u00e0 la temp\u00e9rature \u00e9lev\u00e9es, ce qui le rend id\u00e9al pour les pi\u00e8ces complexes.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Le PEEK est un plastique de plus en plus utilis\u00e9 en substitution des m\u00e9taux<\/h2><\/div>

Le PEEK, poly\u00e9ther \u00e9ther c\u00e9tone, est un polym\u00e8re thermoplastique organique.\u00a0C’est le polym\u00e8re le plus courant de la famille PAEK (polyaryl\u00e9therc\u00e9tone).\u00a0Depuis sa premi\u00e8re commercialisation en 1978, les propri\u00e9t\u00e9s PEEK sont utilis\u00e9es dans un nombre toujours plus croissant d’applications exigeantes.<\/p>\n

Avec ses propri\u00e9t\u00e9s m\u00e9caniques \u00e9lev\u00e9es et un point de fusion \u00e0 343\u00b0C, le PEEK offre des performances \u00e9lev\u00e9es pour une large gamme de propri\u00e9t\u00e9s.\u00a0 Ce polym\u00e8re est tr\u00e8s r\u00e9sistant \u00e0 la d\u00e9gradation thermique et diff\u00e9rentes qualit\u00e9s permettent une utilisation \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es ou basses.<\/p>\n

Le mat\u00e9riau PEEK pr\u00e9sente \u00e9galement une bonne r\u00e9sistance chimique, bien qu’elle ne soit pas aussi large que celle des fluoropolym\u00e8res.\u00a0Il pr\u00e9sente une bonne isolation \u00e9lectrique et thermique.<\/p>\n

Le mat\u00e9riau PEEK est souvent le polym\u00e8re de r\u00e9f\u00e9rence lorsque l’on consid\u00e8re une substitution de pi\u00e8ces m\u00e9talliques par des polym\u00e8res haute performance dans les pi\u00e8ces critiques.<\/p>\n

Il est \u00e9galement beaucoup plus l\u00e9ger que le m\u00e9tal (3 \u00e0 5 fois plus l\u00e9ger) et offre une bonne stabilit\u00e9 thermique.\u00a0Par cons\u00e9quent, il est souvent utilis\u00e9 pour remplacer des pi\u00e8ces m\u00e9talliques dans des environnements difficiles. C\u2019est souvent le pas par exemple pour des paliers.\u00a0Il pr\u00e9sente \u00e9galement d’excellentes propri\u00e9t\u00e9s d’\u00e9tanch\u00e9it\u00e9 dans des composants tels que les si\u00e8ges de vanne.<\/p>\n

En substitution du m\u00e9tal, il est \u00e9galement utilis\u00e9 dans une grande vari\u00e9t\u00e9 de pi\u00e8ces inject\u00e9es : ressorts et engrenages par exemple ont beaucoup d’atouts face \u00e0 leurs homologues m\u00e9talliques en termes d’efficacit\u00e9 et de r\u00e9duction du bruit.<\/p>\n<\/div>\n

          Le PEEK existe en diff\u00e9rents grades, et diff\u00e9rentes qualit\u00e9s.\u00a0Ces grades d\u00e9pendent du proc\u00e9d\u00e9 de transformation (injection, moulage\u2026), mais plus important encore des propri\u00e9t\u00e9s finales.\u00a0Par exemple, certains grades offrent une temp\u00e9rature de transition vitreuse jusqu’\u00e0 170\u00b0C.\u00a0D’autres peuvent \u00eatre utilis\u00e9s \u00e0 basse temp\u00e9rature.\u00a0Une bonne connaissance des diff\u00e9rents grades et des diff\u00e9rents fournisseurs est donc un atout pour transformer une bonne mati\u00e8re.<\/p>\n
          \n

          De plus, les compounds \u00e0 base de PEEK sont de plus en plus utilis\u00e9s dans l’industrie pour am\u00e9liorer ses propri\u00e9t\u00e9s.\u00a0Les charges les plus courantes incluent:<\/p>\n

            \n
          • PTFE<\/li>\n
          • Carbone<\/li>\n
          • Graphite<\/li>\n
          • Fibres de verre<\/li>\n<\/ul>\n

            L\u00e0 encore, les charges ont un fort impact sur toutes les propri\u00e9t\u00e9s, et atteindre les bonnes performances implique une solide connaissance des mat\u00e9riaux de matrice et de charge, ainsi que des proc\u00e9d\u00e9s de m\u00e9lange et de transformation.<\/p>\n

            Le PEEK est \u00e9galement couramment utilis\u00e9 en tant que matrice de mat\u00e9riaux composites.\u00a0Avec sa plage de temp\u00e9rature \u00e9lev\u00e9e, son comportement est dans ce cas proche des pi\u00e8ces m\u00e9talliques, tout en divisant son poids par 3 \u00e0 5.<\/p>\n<\/div>\n
