Thermoplastic PO and reactive PUR hot melt adhesives from Jowat facilitate a laminated activated charcoal filter media with a high permeability of the compound. The absorption capacity and the breathability of the filter media is influenced by the lamination of the multiple layers. The necessary compound strength of the filter media is already ensured with a minimal application amount in manufacturing. Therefore, as much surface as possible remains free for air filtration to provide clean air and for high breathability.
PO as well as PUR hot melts from Jowat facilitate a fast processing of the filter media and therefore efficient manufacturing due to optimum spraying performance and high green strength, and support all further downline processing steps. Both adhesive systems are characterised by low fogging and emissions, and are odourless.
Jowat adhesives for filters meet the high heat resistance demanded in the automotive industry and facilitate the manufacture of cabin filters in original equipment quality.
When filters for passenger compartments are manufactured that are to provide clean air for the vehicle interior, a variety of materials in several layers is bonded in a series of inline steps.
The filter materials assembled this way protect the passengers from dust, pollen, rust, bacteria, and odours, and also against gaseous pollutants like benzene or ozone.
When considering the ecological fingerprint of a car, these filters are playing an important role. This means that the adhesive used may not impair the performance of the filter in any way.
