Melt flow resistance tester.The XNR-400 melt flow indexer measures the melt flow resistance (MFR MFR, n See myofascial release. ) of a wide range of thermoplastics. This tabletop tester conforms to all national and international melt flow resistance standards, including BS, EN, ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. 1133 and ASTM ASTM abbr. American Society for Testing and Materials D1238, according to the company. Any temperature within 120[degrees]C to 450[degrees]C (248[degrees]F to 842[degrees]F) can be accurately controlled, according to the manufacturer. The XNR400 melt flow indexer has a built-in microprocessor that maintains the temperature control to within [+ or -] 0.2[degrees]C ([+ or -] 0.4 F), with rapid ramp-up to set point. Extruded material is automatically cut off by the built in scraper See scraping. mechanism at preset intervals, controllable to [+ or -] 0.01 seconds. The XNR-400 ix supplied complete with spare barrel and die, plus all the accessories and weights necessary for maintenance and operation, according to the company. There are no other accessories or components to buy. Users simply plug in the XNR-400 melt flow indexer and begin testing, according to the manufacturer. The company manufactures and markets physical property testing instruments for the robber, plastic, coatings, textile, nonwoven non·wo·ven adj. Made by a process not involving weaving. Used of textiles. n. Material or a fabric made by a process not involving weaving. and other industries. (Testing Machines) Circle 103 on card |
