Co-Extruded Rubber Profiles

The most common and by far the most important application of the EPDM based sealing system in an automobile is the door seal (co-extruded profiles). These are dynamic seals which seals the door with the door flange firmly to avoid dust, water & air to leak inside the cabin. The same sealing system is also used in Deck lid sealing, bonnet sealing and similar other applications. The seals are also very important as far as aesthetics is concerned. It takes care of the door & Body flange panel variations and gives a smooth look from outside.
Functional parameters are easy fitment on the sash but high retention force after fitment and the desired level of force required in the closure of the door. The important design parameters like Compression load deflection force, insertion and retention force are the reflection of these factors.
