This video provides an overview of the FiloSeal+Duct Seal system, showing how it is installed and detailing its key technical features.
The Filoform duct sealing system FiloSeal+ uses our MD+ sealant which is easily applied from a standard skeleton gun. The high quality, one component, flexible sealant “MD+” is based on a silicon compound that cures with air (Humidity).
After application and full curing the thixotropic MD+ forms a plastic elastomer mass with special qualities effectively sealing and bonding, while providing a high level of durability.
FiloSeal+ is very easy to apply regardless of the type of cable scenario in the cable ducts as it uses a uniquely shaped foam piece which positions neatly around the cables or pipes in the duct.
The unique design of the tri-flexible foam makes positioning and separation of the cables very simple while also providing a backing for the MD+ to be applied on.
This seal is easily installed in vertical scenarios while providing the added security of ensuring no loss of components down the duct.
FiloSeal+ is suitable for sealing several cables or pipes contained in one duct and also allows re-entry of the seal to add or remove cables or pipes as required.
