PU ester filter foam
PU ester filter foams – open-cell foam for air filtration, sound insulation and wind absorption
The black filter foam made from PU ester is an open-cell, elastic and durable technical foam, which is primarily used in industrial applications for air filtration, noise reduction and wind absorption. Its open-cell structure ensures that air can flow through unhindered, whilst particles, noise or airflow effects are dampened. This makes the material ideal for devices, machines and systems where functional air permeability is required without having to sacrifice filtering or damping effects.

The black filter foam made from PU ester is an open-cell, elastic and durable technical foam, which is primarily used in industrial applications for air filtration, noise reduction and wind absorption. Its open-cell structure ensures that air can flow through unhindered, whilst particles, noise or airflow effects are dampened. This makes the material ideal for devices, machines and systems where functional air permeability is required without having to sacrifice filtering or damping performance.
The filtration performance is determined by the defined pore size, which is classified using the unit PPI (pores per inch). The designation PPI 15, 20, 30, 35, 45 or 60 means that the foam has 15, 20, 30, 35, 45 or 60 pores per inch. Depending on the PPI value, this pore design enables coarser to finer filtration and a corresponding air flow rate, making the filter foam particularly suitable for applications such as pre-filters in ventilation and air-conditioning systems, flow damping in fans and compressors, wind protection for microphones and sensors, or the acoustic damping of air flows in technical enclosures. Furthermore, PU ester filter foam is used in applications where flow noise needs to be reduced, such as in soundproofing construction or in the design of low-noise air ducts.
The filter foam is easy to work with and can be cut, punched, glued or fabricated into contoured moulded parts, enabling optimal adaptation to a wide range of technical requirements. Our online shop offers a wide selection of filter foams with different PPI values (15, 20, 30, 35, 45 and 60) and thicknesses, so that the right quality can be selected for every application. Order the filter foam you need conveniently online or contact us if you require advice on selecting the appropriate pore size or custom-cut pieces. We are happy to assist you in optimising the design of your project.
