Acoustic solutions

The challenges today’s acoustic product solutions have to meet is inherent in the protection of highly sensitive electronics against dust and liquids and to simultaneously prevent negative effects on the acoustic properties.

The use of our microporous TRAKETCH^® Filter Membranes (PFOA-free), the cylindrical pores of which can be perfectly size adjusted during the manufactur-ing process, puts us in a position to guarantee the concise achievement of this goal. TRAKETCH^® Filter Membranes preserve the application specific sound quality / transparency, including all acoustic properties. At the same time, they protect sensitive electronics, such as loudspeakers and microphones against external impact.

Our product portfolio ranges from membranes on rolls to preassembled membrane components to the development of complex component groups in combination with plastic injection molds.
