VESTAMID® DX9304 BK E70238

Chemical Family: Polyamides

VESTAMID® DX9304 BK E70238 is an extrusion compound specifically developed for the manufacturing of tubing systems that require higher heat resistance. With a melting point approximately 35 °C higher than PA 11 and PA 12 compounds, VESTAMID® DX9304 BK E70238 allows for elevated temperatures during use. This compound is particularly well-suited for extruding tubing systems that are exposed to high burst pressures and high service temperatures, such as hydraulic clutch lines. Thanks to its low moisture absorption, the dimensions and properties of parts remain largely unaffected by ambient conditions. Choose VESTAMID® DX9304 BK E70238 for its exceptional heat resistance, reliability, and ability to meet the demanding requirements of tubing systems.
