TECAMID 66/X GF50 black

PA 66 50% glass fibre reinforced

TECAMID 66/X GF50 black is a PA66 GF50 50% glass fibre filled material based on a partially crystalline polyamide with partial aromatic components for improved thermal stability. In addition to the heat stabilization, this material has been reinforced by a higher percentage of glass fibres than is typically seen with extruded products. As a result, this special glass filled Nylon can be used at high service temperatures up to 130°C under high loads, while still demonstrating very low warpage.
