ULTRA-HIGH STRENGTH UHMW PE FIBERS AND PRODUCTS

Multi-filament UHMW PE fibers can be produced according to processes that result in improved properties. The UHMW PE can have an intrinsic viscosity in decalin at 135 C of at least about 30 dl/g, and can be processed under optimal conditions to achieve a gel spun fiber having a tenacity of greater t...

Zusammenfassung:	Multi-filament UHMW PE fibers can be produced according to processes that result in improved properties. The UHMW PE can have an intrinsic viscosity in decalin at 135 C of at least about 30 dl/g, and can be processed under optimal conditions to achieve a gel spun fiber having a tenacity of greater than about 45 g/denier (40.5 g/dtex). Las fibras multi-filamento de UHMW PE pueden producirse de acuerdo con los procesos que resultan en propiedades mejoradas. El UHMW PE puede tener una viscosidad intrínseca en decalina a 135°C de al menos alrededor de 30 dl/g, y puede procesarse bajo condiciones óptimas para lograr una fibra de hilado en gel que tiene una tenacidad mayor de alrededor de 45 g/denier (40.5 g/dtex).
