Abstract
Multi-filament UHMW PE yarns 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 yarn having a tenacity of greater than about 45 g/d (40.5 g/dtex).
