Sealing profiles

Sealing Profiles for Fire Prevention -
with Expanding Cord Insert

Sealing profiles for channels. Made from EPDM according to EN 45545-2 with an embedded Ø 4 mm round cord made from a graphite material (PROMASEAL®-LX). This sealing system reaches EN 45545-2 as the cord expands under heat creating the smoke sealing that is necessary.

Typical uses for the product is in railway industry where doors or panels may be sealed in such a way that if a fire would start, the expanding profiles would effectively seal off the enclosure from the train, preventing noxious fumes and smoke to enter the area where people are present inside the train compartment. Also, the goal is to smother the existing fire by preventing oxygen to enter the enclosure.

The cord insert expands up to 22 times it's original size when exposed to heat over 190° and creates a thermally stable "foam" that insulates and seals against the hot gases from the fire.

Sealing profile: EPDM. black. Expanding cord: Graphite (PROMASEAL®-LX)

Available in the following formats:
A) The expanding cord is inserted into the top of the sealing profile after the extrusion process.
