Ultimate RF performance

PREPERM™ materials boost the antenna performance to new levels. They also provide solutions for tomorrow’s mmWave frequency demands. Patented PREPERM™ technology gives you a headstart compared to other plastic materials currently used in RF applications.


Consistent antenna performance

Consistency is an outcome of controlled dielectric performance and stable product quality. Homogenous composition makes PREPERM™ virtually isotropic.


Highest antenna efficiency

PREPERM™ leads to energy savings and better product performance through low dielectric losses – even at mmWave frequencies.


Reliability in extreme weather conditions

Stable dielectric properties even in humid and warm environments. Good mechanical properties also after ageing and in low temperatures.


Looking for replacement for ceramic materials?

Achieve significantly better performance and lower total costs by replacing the plastic currently used in your design.


Take a trip to a third dimension

PREPERM™ fits your design – not vice versa. Producing complex 3D shapes has never been easier. From now on the only limits are set by your imagination.


Lower total costs through mass manufacturing

Light-weight plastic materials enable fast and simple production processes. Efficiency leaps equal savings of time and money.
