Polystone® P Copolymère Le polypropylène offre une excellente résistance chimique et est facilement usiné, fabriqué et soudé. Le copolymère offre une force d'impact plus élevée que l'homo-polymère PP, en particulier dans les températures froides aussi basses que –40 ° F.
Propriétés clés
Résistance chimique
Coût relativement bas
Meilleure force d'impact que l'homo-polymère pp
Limites
Force d'impact plus faible que le HDPE
Mauvaise résistance aux solvants aromatiques, aliphatiques et chlorés.
Applications
Réservoirs et doublures structurels
Tonneaux de placage
Conduits et cagoules de fumée
Équipement de traitement des semi-conducteurs
Dispositifs orthopotiques et prothétiques
Composants de pompe et de vanne
