20120121852 | HIGH STRENGTH TAPE ARTICLES FROM ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE - Tape articles having improved properties are made from ultra-high molecular weight (UHMW) multi-filament yarns. The tape articles can have a ratio of the low temperature area under the curve (120° C. to Tm-onset) to the total area under the curve (120° C. to 165° C.) of less than about 0.15 as calculated from an increasing temperature DSC scan from a temperature of 30° C. to a temperature of 200° C. at a constant rate of 10° C. per minute. Additionally, in some examples the tape articles can also have a tenacity at least about 24 g/d (2.06 GPa) when measured by ASTM D882-09 at a 10 inch (25.4 cm) gauge length and at an extension rate of 100%/min. Further, the tape articles can have no long period of less than 450 Angstroms (Å) when measured by small angle x-ray analysis. | 05-17-2012 |
20120258301 | HIGH STRENGTH ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE TAPE ARTICLES - Processes for the production of high strength polyethylene tape articles from high strength ultra-high molecular weight multi-filament yarns, and to the tape articles, fabrics, laminates and impact resistant materials made therefrom. | 10-11-2012 |
20130202844 | MULTIDIRECTIONAL FIBER-REINFORCED TAPE/FILM ARTICLES AND THE METHOD OF MAKING THE SAME - High tenacity, high elongation multi-filament polymeric tapes as well as ballistic resistant fabrics, composites and articles made therefrom. The tapes are fabricated from multi-filament fibers/yarns that are twisted together, bonded together, compressed and flattened. | 08-08-2013 |
20130225022 | HIGH TENACITY HIGH MODULUS UHMWPE FIBER AND THE PROCESS OF MAKING - Processes for preparing ultra-high molecular weight polyethylene (“UHMW PE”) filaments and multi-filament yarns, and the yarns and articles produced therefrom. Each process produces UHMW PE yarns having tenacities of 45 g/denier to 60 g/denier or more at commercially viable throughput rates. | 08-29-2013 |
20140030947 | NOVEL UHMWPE FIBER AND METHOD TO PRODUCE - Processes for preparing ultra-high molecular weight polyethylene yarns, and the yarns and articles produced therefrom. The surfaces of highly oriented yarns are subjected to a treatment that enhances the surface energy at the yarn surfaces and are coated with a protective coating immediately after the treatment to increase the expected shelf life of the treatment. | 01-30-2014 |
20140065913 | NOVEL UHMWPE FIBER AND METHOD TO PRODUCE - Processes for preparing ultra-high molecular weight polyethylene yarns, and the yarns and articles produced therefrom. The surfaces of partially oriented yarns are subjected to a treatment that enhances the surface energy at the fiber surfaces and are coated with a protective coating immediately after the treatment to increase the shelf life of the treatment. The coated, treated yarns are then post drawn to form highly oriented yarns. | 03-06-2014 |
20140170429 | LAMINATES MADE FROM ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE TAPE - Disclosed are laminates from multiple stacked plies of a uni-directional tape in which the tape formed from a plurality of ultra-high molecular weight polyethylene gel spun, multi-filament yarns. The resultant laminate contains not more than five percent resin by weight. Related methods of making a laminate of this type are also disclosed. | 06-19-2014 |
20140190343 | HIGH STRENGTH ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE TAPE ARTICLES - Processes for the production of high strength polyethylene tape articles from high strength ultra-high molecular weight multi-filament yarns, and to the tape articles, fabrics, laminates and impact resistant materials made therefrom. | 07-10-2014 |
20140272268 | HIGH STRENGTH TAPE ARTICLES FROM ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE - Tape articles having improved properties are made from ultra-high molecular weight (UHMW) multi-filament yarns. The tape articles can have a ratio of the low temperature area under the curve (120° C. to Tm-onset) to the total area under the curve (120° C. to 165° C.) of less than about 0.15 as calculated from an increasing temperature DSC scan from a temperature of 30° C. to a temperature of 200° C. at a constant rate of 10° C. per minute.
