描述
VESTAMID CW1442 BK is a highly filled, carbon fiber reinforced and heat-stabilized compound based on polyamide 12 (PA12) from Evonik Operations GmbH. It is generally used for components manufactured in the injection molding process and is especially suitable for applications requiring high stiffness, high strength, and high impact resistance.
The PA12 compound absorbs only small amounts of water. Therefore, components made from this material have an excellent dimensional accuracy with changing ambient humidity. Due to the low melting point of VESTAMID CW1442 BK, the material provides a wide processing window for the injection molding process. The compound is suitable for applications requiring a high ratio of flow length to wall thickness.
The carbon fiber reinforcement provides electrical conductivity in addition to high mechanical performance, making it suitable for applications requiring electrostatic discharge (ESD) protection or electromagnetic interference (EMI) shielding.
VESTAMID CW1442 BK is supplied as cylindrical granules ready for processing, in moisture barrier bags. The use of colorants can change property values.
