Profile foamed seals for heatsinks and cases


In order to achieve satisfactory sealing, including IP and/or EMC protection of components and heatsinks against parts of the casing, the use of profile foamed seals is very expedient. The sealing compound made from polyurethane free from CFC is permanently elastic and can be foamed in almost any contour and dimension. By filling a groove or surface mounted, the sealing becomes an un-detachable, integral part of the heatsink. By proper selection and adaptation of the sealant and its filler materials it can be used for virtually every application, as the width and thickness of the foam can also be adjusted to suit specific needs. When a heatsink provided with a profile foamed seal is fastened to a case etc., handling is significantly easier as, unlike in the case of flat seals which are inserted between the heatsink and the case, incorrect installation is prevented. All profile foamed seals can be applied to standard heatsinks, parts of casings or to customized versions. For any enquiries or further details, please contact the Fischer Elektronik product specialists. They will be pleased to give you any advice you may require.
