Product Texts

Glass fiber reinforced injection molding grade for plastic parts in electronic components like housings for electronic control units or connectors. Ultramid EQ (Electronic Quality) materials offer a high purity regarding ionic and halogen containing compounds. This helps to minimize potential corrosion processes and to protect sensitive electronic components.
The product has a LS coloration (Laser Sensitive) and can be marked with Nd:YAG lasers.
