Filoform MDIV Cable Duct Sealing System Description

Filoform MDIV cable duct sealing system is a quick and easy sealing of empty ducts or boreholes where cables or pipes are to be installed at a later date. The Filoform MDIV system provides an effective Gas and Watertight seal of underground cable penetrations. Filoform MDIV is specified and used by major Electrical, Gas, & Water Utililty companies in the UK and Benelux countries.

Filoform MDIV will protect valuables from damage which is caused by gas and water leaks. The Filoform MDIV sealing system is suitable for ducts with a diameter of 75mm up to 160mm.

Filoform MDIV sealing systems are based on a specially formulated two-component expanding polyurethane resin. The polyurethane sealant is packed in a transparent plastic bag with a screw ring where the two components are separated by a clamping profile. After removal of the clamping profile, the two components are simply mixed together for 30 seconds. The Filoform MDIV package is now ready for use and can be easily opened with the use of the screw nipple.

After pouring the Filoform MDIV resin in the duct, the resin starts expanding by forming CO². During the expansion the Filoform polyurethane filling material penetrates all areas inside the duct and sealing all openings regardless of the shape of the duct or borehole, then the hardening process starts. The Filoform MDIV two component filler provides not only a 100% gas and watertight seal but also offers excellent mechanical strength.

Filoform MDIV duct sealing system seals all know materials, PVC & PE sheathed cables, PILC, (HD) PE pipes
