EMS-Grivory Grivory® GVL-5H nat PA*-GF50
Categories:	Polymer; Thermoplastic; Nylon (Polyamide PA)
Material Notes:	Product description: Grivory GVL-5H natural is based on a combination of a heat stabilized semi-crystalline Polyamide with a partially aromatic Polyamide and 50% long glass fibers. Grivory GVL-5H natural is characterized by the following key-properties: high stiffness and strength even after conditioning and over a wide temperature range excellent notched impact resistance also at low temperatures low creep high heat distortion temperatures low moisture absorption very good dimensional stability and little warpage The product has been designed for injection molding of technical parts especially in the area of die-cast metal replacement. Grivory GVL-5H natural is used in the following market segments: automotive mechanical engineering household and appliances The glass-fibers are aligned in parallel and are just as long as the pellets (usually 10 mm).
