PREPERM® Components
Extremely low losses, very low water absorption and good temperature resistance. Combining these properties with cost-efficiency makes PREPERM® screws, nuts and washers a very competitive alternative to PEI or PEEK.
PREPERM® components can be used in RF filters, RF combiners, antennas, or wherever you need low-loss dielectric fasteners.

PREPERM® Filaments for 3D printing
PREPERM® 3D filaments are good for quick prototyping when you want to validate a new concept. You can create structures which are impossible to make with any other manufacturing method!
The dielectric constant of our filaments range from 3 up to 10. They are ABS-based and can be printed with conventional FDM printers. The PREPERM® 3D filaments come in 750 g spools with a dimension of 1.75 mm.
