描述
VESTAMID DX9304 BK E70238 is a high-viscosity, impact-modified, heat- and light-stabilized polyamide 612 (PA612) extrusion compound from Evonik Operations GmbH. It is specifically developed for the manufacturing of tubing systems with higher demands on heat resistance.
The melting point of VESTAMID DX9304 BK E70238 is approximately 35°C higher than PA11 and PA12 compounds, allowing for elevated temperatures during use. This makes the compound especially suitable for the extrusion of tubing systems that are exposed to high burst pressures at high service temperatures, such as hydraulic clutch lines.
The material absorbs only little moisture. Therefore, dimensions and properties of parts are nearly unaffected through ambient conditions. The compound is supplied as black granules and is electrically insulating, impact-resistant, and stabilized against heat and light.
