Abstract[English]
Gel-spun ultra-high molecular weight ultra-high molecular weight polyethylene (UHMWPE) polyethylene filaments are disclosed which are optimized for their use in permanent load applications. Yarns comprising at least 25 permanent load optimized UHMWPE filaments, a titer of at least 50 dtex, a filament titer of at least 0.50 dtex, a tensile modulus of at least 1500 cN/dtex and a minimum creep rate of at most 5.0x10-7 s-1 when measured at 70°C under a load of 400 MPa are also disclosed. The UHMWPE may be a linear homopolymer of ethylene. The load optimized filaments and various products such as ropes, nets, medical devices, fabrics, laminates, composite articles and ballistic-resistant articles containing the filaments or yarns are also disclosed.[French]
Des filaments de polyéthylène à ultra haut poids moléculaire (PE-UHPM) filés en gel sont divulgués, qui sont optimisés pour leur utilisation dans des applications de charge permanente. Des fils comprenant au moins 25 filaments de PE-UHPM optimisés pour charge permanente, un titre d'au moins 50 dtex, un titre de filament d'au moins 0,50 dtex, un module d'élasticité en traction d'au moins 1 500 cN/dtex et un taux de fluage minimal d'au plus 5,0 x 10-7 s-1 lors d'une mesure à 70 °C sous une charge de 400 MPa sont également divulgués. Le PE-UHPM peut être un homopolymère linéaire d'éthylène. Les filaments optimisés pour charge et divers produits tels que des cordes, des filets, des dispositifs médicaux, des tissus, des stratifiés, des articles composites et des articles pare-balles contenant les filaments ou les fils sont également divulgués.
