Plastic pipes which pass through fire-rated bulkheads and decks as part of, for example, sanitation systems, create serious problems in case of fire. Most plastic pipes start to soften at a temperature of about 75°C and ignite at a temperature of about 140°C. This means that should a fire occur, a hole will be formed by the softened or combusted plastic pipe, allowing fumes and flames to spread freely.
RISE Ultra plastic pipe penetrations are a newly developed version of Beele Engineering and CSD's CRUSHER technology used in all our RISE products. It uses a combination of adhesion followed by rapid and extreme expansion, resulting in a solid, stable filling of the conduit opening, closing off any gaps left by the melting plastic pipe. The RISE Ultra's effectiveness comes from its reaction at two different temperature levels. Firstly, the rubber becomes very adhesive, bonding itself to the ducted pipe and then following the initial stage of expansion, bonding itself to the inside wall of the conduit opening. The next stage of the reaction as the temperatures increase further is a huge expansion of material which crushes the softening plastic pipe quickly and prevents any smoke or fire breakthrough. The resulting rubber mass is then extremely stable and will withstand extended exposure to fire.
