Title (EN) SINTERED AND POROUS ARTICLES HAVING IMPROVED FLEXURAL STRENGTH
(FR) ARTICLES FRITTÉS ET POREUX PRÉSENTANT UNE RÉSISTANCE À LA FLEXION AMÉLIORÉE
Abstract:
(EN) Polymer compositions containing polyethylene particles having a multi- modal molecular weight distribution are disclosed. The polymer compositions are well suited to producing porous substrates through a sintering process. Formulations made according to the present disclosure can produce porous substrates having improved flexibility demonstrated by an increased flexural strength while still retaining excellent pressure drop characteristics.
(FR) L'invention concerne des compositions polymères contenant des particules de polyéthylène possédant une distribution de masse moléculaire multimodale. Les compositions polymères sont bien appropriées pour produire des substrats poreux par l'intermédiaire d'un procédé de frittage. Les formulations fabriquées selon la présente invention peuvent produire des substrats poreux présentant une flexibilité améliorée démontrée par une résistance à la flexion accrue tout en conservant d'excellentes caractéristiques de perte de charge.
