World demand for optical fibers crock pot lunch crock food warmer increases, as far as the available space for overhead transmission lines and conduits, wiring and buildings crock pot lunch crock food warmer and optoelectronic components. Cables have to be thinner while maintaining the same capacity. To meet the growing demand, BASF has developed a new variety of Ultradur specifically for thin optical coatings. Ultradur is a brand developed by BASF semi-crystalline, thermoplastic saturated polyester-based PBT (polybutylene terephthalate). The new species crock pot lunch crock food warmer is named Ultradur B6550 LNX and has excellent mechanical properties even thinner. Thus, BASF is expanding its existing product line Ultradur extrusion coatings for optical fibers. In contrast to PBT species optimized for injection molding materials crock pot lunch crock food warmer are characterized by their high molecular weight and high viscosity. Internet traffic is growing along with the demand for telephone, cable and industrial connections, crock pot lunch crock food warmer such as communications equipment crock pot lunch crock food warmer to control crock pot lunch crock food warmer the electricity network. This requires a thinner and more efficient fiber with thinner coatings. At the same time the optical fibers must still be protected under all circumstances. It can only provide a plastic coating which has particularly good mechanical properties such as stiffness. Cables used for optical signal transmission have a complex structure. Up to 12 glass fibers transmitting light may consist of the so-called. shroud loose tube with a rigid stabilizing polybutylene terephthalate (PBT). The coating takes place in a fully automated process of extrusion tubes, wherein the individual fibers are taken from separate spools at a speed of from 100 to 500 meters per minute and at the same time introduced into the extruded tube. In order to facilitate the production of thin cable cover BASF has developed Ultradur B6550 LNX that provides at least as good as the previous crock pot lunch crock food warmer resistance to bending with a much thinner shell surrounds crock pot lunch crock food warmer loose tube. The material has a high yield strength and higher modulus of elasticity. The result is much stiffer, usually accompanied by brittleness. However, in this case, BASF managed to combine low friability of high modulus of elasticity - which means a considerable elongation crock pot lunch crock food warmer at break. Ultradur B6550 LNX addition, due to the partially crystalline morphology, shows an even more rapid than the standard PBT crystallization and has a very high melt viscosity, especially at low shear rates. Both properties are preferred in the extrusion process. A key indicator for assessing the quality of the user with the protective coating is resistant to crushing. It describes the homogeneity of the sheath around the loose tubes, and the crushing strength. To measure the resistance to crushing of a specified length of the cable is fixed in a holder, and then sends the signal light by subjecting the cable pressure until the signal is suppressed to a value of 0.05 dB. Measured value is the maximum force (in N / dm), which cable can withstand until they reach the attenuation in the fiber. Present on the market today based coating materials offer PBT crushing strength of about 600 N / dm for the cable outer diameter of 2 mm and about 1.5 mm inside. New Ultradur B6550 LNX has twice the value of the crushing strength (1350 N / dm). With the new material, if desired, may be at the same thickness of the cable for its increased resistance to crushing. Its value is determined crock pot lunch crock food warmer in the laboratory of one of the world's leading manufacturers of fiber optic cables. crock pot lunch crock food warmer See also: BASF: a new way to control global coffee BASF PS: financial results for the first half. 2013 BASF Polymer strategy "Innovation Marketplace 2013" in Warsaw, New variants of BASF BASF's plastics job cuts Impressive results BASF constant AH salt in Ludwigshafen BASF invests at CBS in the Gulf of BASF: profit decreased by 21%, a record year Breakthrough BASF BASF's crock pot lunch crock food warmer investment in Asia announces new strategy Jaroslaw Michniuk exited from BASF BASF Plastics support Direction - Record results of engineering plastics from BASF German rivalry crock pot lunch crock food warmer in PA and PBT new investor for Styrolution!
