Trelleborg Sealing Solutions has three technical cleanliness standards based on accepted international standards:
1. Defined particulate cleanliness As components and assemblies become smaller, more complex and have higher efficiency, functional density is increased. This narrows tolerances and makes component parts more sensitive to particle contamination.
2. Freedom from paint wetting impairment substances Clean components are a particular requirement within the lacquering process. The surface to be lacquered, as well as the smallest components within the painting system, have to be free from any contamination that may cause disturbances or disorders in the lacquered wettings.
3. Class 5 cleanroom quality, ISO 14644 – 1 Some automotive components, such as electronic parts, require the ultimate in clean production, with the slightest contamination, even from airborne particles, potentially affecting component function. This is eliminated using cleanroom production where the concentration of airborne particles is controlled.
Flexcoat™ : Friction-free running
Trelleborg Sealing Solutions has developed a number of micro-thin performance coatings and surface modifications that improve the friction performance of elastomer seals. Choosing one of these has the following benefits:
