Application

Expands under heat to seal gaps around cables cable trays and ladders and also to close off plastic pipes and insulated metal pipes (elastomeric and glass wool insulation). The product seals penetrations in flexible and rigid walls (≥100 mm) and floor constructions. Consult technical literature for specific applications details.

Description

PROMASEAL®-HPEx Sealant is an acrylic-based graphite sealant used to reinstate the fire resistance performance of wall and floor constructions where they are penetrated by various cables, plastic and insulated metal pipes.

The sealant expands upon contact with heat and is considered as an intumescent or reactive material. The high expansion ratio causes it to swell upon heating and can achieve a fire rating up to 240 minutes.

Features and benefits:

  • UL-EU Approval.
  • CE marked.
  • Paintable and odourless.
  • Expands up to 20 times original dimension.
  • Air, water, smoke and gas tight.
  • Minimum seal depth: ≥25 mm.
  • Angular gap width: ≤20 mm.
  • Available in 310 ml cartridges.
