Evonik VESTAMID® LC-GF23 NC Nylon 12, 23% Glass Fiber Reinforced
Categories:	Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 12 (PA12); Nylon 12, 20% Glass Fiber Filled
Material Notes:	VESTAMID® LC-GF23 NC is a semi-crystalline, heat- and UV-stabilized compound based on PA 12 from which connectors are preferrably produced by injection molding. The polyamide compound is especially suitable for the automotive and mobility sector. The semi-crystalline molding compound absorbs only small amounts of water. Components made from VESTAMID® LC-GF23 NC therefore have excellent dimensional accuracy with changing ambient humidity and constant general chemical stability. The semi-crystalline polymer is characterized by its outstanding mechanical and thermal load capacity. Molding or process-specific deviations from the recommended processing parameters are possible to a certain extent if the cavity or the process requires it. VESTAMID® LC-GF23 NC is delivered as cylindrical-granules in ready-to-process condition, in moisture-tight packaging. Preliminary data sheet.
