Polyurethane foam for sealing against water and gases, yields up to 8 2" conduits

Polywater FST-250KIT Duct Sealing Foam against water and gases.

Code FST-250KIT

The Polywater FST-250KIT polyurethane sealing foam kit is a professional solution for protecting electrical conduits, telecommunications ducts, and cable entries against the penetration of water, methane, gases, humidity, dust, insects, and rodents.

Polywater FST sealant uses two-component closed-cell foam technology, which flows around cables and into the duct space to form a strong bond. Once applied, the material expands and cures to form a rigid, robust, semi-permanent, yet removable seal for future interventions.

It is recommended for ducts 50 mm / 2" or larger and is ideal for installations where reliable sealing is required in demanding environments, such as electrical rooms, manholes, substations, poles, cabinets, meters, combiner boxes, solar systems, underground networks, and telecommunications ducts.

Polywater FST stands out from common foams because it creates airtight and watertight seals, is fire retardant, and complies with applicable electrical codes for sealing conduits and building entries. In addition, it withstands continuous water pressure of 6.7 m / 22 feet and overpressures of up to 27 m / 90 feet.

The FST-250KIT includes a 250 ml FST sealing foam cartridge, mixing nozzles, foam containment strips, abrasive cloth, gloves, positioning rod, pre-treatment wipe, resealing cap, and instructions. The TOOL-250 is not included and is sold separately.
