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.
PREPERM® components can be used in RF filters, RF combiners, antennas, or wherever you need low-loss dielectric fasteners.
PREPERM® PEEK screws combine excellent RF properties, very good mechanical performance and outstanding thermal stability. This makes PREPERM® PEEK screws a very competitive solution for applications where mechanical strength and thermal stability are valued.

PREPERM® Filaments for 3D printing
Traditionally, prototyping has been carried out by mechanical machining. However, this is a slow manufacturing method which generates material waste. 3D printing technology significantly simplifies the manufacturing process and can generate complex perforated structures that are difficult to achieve by any other technology.
PREPERM® 3D filaments take you a step further with optimized dielectric properties - they are designed for rapid prototyping when you want to validate a new concept. The dielectric constant of our filaments ranges from 3 up to 12. 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.
