Extruded sections provide a simple and effective means of sealing to common IP ratings, such as IP44, IP55, IP65, IP66. EMKA gaskets seal against ingress of dust or liquids when installed face-to-face between a door and cabinet frame. Other sections install edge-to-face and yet others seal inspection windows or provide a wiping action. Paint protection and compensation of varying gap thicknesses are further important factors in gasket application.
Extruded gaskets for enclosures and other purposes are available in self-adhesive, self-grip (clip-on), channel fixing and window type (with expansion insert). The EMKA range includes EPDM, NBR, CR, PVC and silicone, as well as many with EMC-compatible coating.
In addition to electrical/electronic enclosures and cabinets, many standard sections are available specifically for applications, such as motor vehicles, railway carriages, and off-road trucks and machines, including agricultural equipment and fire trucks. Coaches and motor homes also feature, with moulded sections to suit doors, windows and ventilation panels, as well as external storage compartments. EMKA also offers a bespoke custom design service – where there is a requirement for a really different profile, then the EMKA team will design, develop and produce to suit specific needs.
The EMKA gasket programme now includes in excess of 730 sections, with or without spring clip mounting spine, for environmental sealing, equipment protection or personnel protection. Profiles in neoprene, epdm, PVC, black nitrate and natural rubber cover traditional expanded closed cell (self-adhesive) foam, through wiping blade and bubble or P type sections, to more complex multi-functional and custom designs.
“Profiles include wiping designs, fillers, and flocked weather strips and supported sections with internal or flange structural support. Specialist considerations regarding shore hardness, tensile strength, recoil elasticity, abrasion resistance and climatic/chemical resistance can also be advised upon and allowed for in custom production,” said the company.
