Material Notes:
Vydyne® 49H NT is general-purpose, impact-modified PA66 resin. Available in natural, it is heat-stabilized for improved resistance to elevated temperatures. The heat-stabilized for improved resistance to elevated temperatures. The heat stabilization package for Vydyne 49H NT was formulated to provide thermal endurance when used in applications in which continuous or extended high-temperature exposure is anticipated. Vydyne 49H NT is recognized for all the processing and property advantages inherent to PA66 with the addition of improved impact strength. This resin offers a well balanced combination of engineering properties characterized by high melt point, good surface lubricity abrasion resistance and resistance to many chemicals, machine and motor oils, solvents and gasoline. Typical Applications/End Uses: Vydyne 49H NT may be used in most market segments, including industrial, consumer, automotive and electrical applications. Typical end uses include clips, fasteners, gears, cable ties, electrical connectors and many other parts that require additional toughness at room and low temperatures.
