描述
VESTAMID DX9310 BK E70399 is a high-viscosity, plasticized, heat- and light-stabilized, impact-modified polyamide 612 (PA612-P-I) extrusion compound from Evonik Operations GmbH. It is specifically developed for the production of tubing systems, such as multilayer tubes used as air brake lines.
Besides optimized processing behavior and improved cold impact resistance, VESTAMID DX9310 BK E70399 offers, owing to a special modification, similar mechanical properties as VESTAMID X7393 (a PA12-based compound typically used for monolayer air brake tubing). Due to these properties, it is suited as the middle layer in multilayer tube 250.1, together with VESTAMID X7393 as the inner and outer layers.
The material absorbs only little moisture. Therefore, dimensions and properties of parts are nearly unaffected through ambient conditions. The compound is supplied as black cylindrical pellets in moisture-proof bags. Pigmentation may affect values.
