Filters

Processing and application of adhesives, sealants and encapsulation

Filters, more precisely fluid filters, are used to withheld solid particles from a gas or liquid flow. The core of this statement already gives a first idea of how widespread the different applications for filters are.

Motor vehicles need oil, fuel and air filters. Activated carbon filters and respirators are widely used in different industries and crafts to clean air, water or protect people from hazardous substances. However, they are also used in medical technology e.g. as Dialyzers – and this is just a small glimpse of the diversity in which filters do their job in almost all areas of life.

Equally diverse are the materials, depending on use, from which filters are manufactured: papers, synthetic fibers, metals, non-woven materials, fiberglass – to name a few. Thus, for example, blood filters are made of a bundle 10,000 to 12,000 fine synthetic hollow fibers, which are embedded in a plastic housing and sealed with a polyurethane potting compound.

In most cases of filter manufacturing different components are bonded, sealed or liquid compounds are metered in potting as well as casting applications. Frame material and filter media are bonded together - while the tightness must be ensured.
