What Are Fire And Heat Resistant Sealants?August 19, 2015
In contemplating the label, sealant, there’s a risk of understating the many functions and applications of a high-quality sealing product. The natural implications of the merchandise, at least those inferred from the label, are as an airtight segregation mechanism. Sound is sliced in twain by the formulation, and the ability of the sealant to conform to every eccentric outline as it flows between surfaces ensures a formidable barrier is generated.. Insulation is another asset. The enclosed area will stay cool in the summer and toasty warm in the winter. But there’s still some question over the actual ingredients within the product. A cautious homeowner wonders if the chemicals are toxic or if they’ll exude fumes if a fire spreads through a building. These are valid concerns, ones that are addressed by safety-conscious chemical engineers.
At least as important as any sealing factor, a product that’s designed to be deposited in a structure where life is found must exhibit safety-centric features. This means the sealant is first of all composed of ingredients that will not combust. That’s a design ethic that’s subsequently reinforced by supplemental design elements, such as a chemical composition that won’t emit fumes, even non-toxic ones that could somehow compromise a delicate respiratory system. Think of this design aspect as the active fire retarding component of the sealant. Of course, on returning to the segregating capacity of the compound, it’s easy to discern the next fire retarding attribute. An airtight seal will prevent heat and smoke from spreading in the event of a catastrophic conflagration. Flames are rising and a fine wisp of smoke is seeking egress to the next room. The sealant stops this dangerous action fast.
The fire retarding and heat resisting properties of the sealant can typically be discerned by taking a closer look at the material safety data sheet associated with the product (safeworkaustralia.gov.au). Pay particular attention to the stability and reactance section of the document, but zero in on the fire-fighting advice section for information regarding combustion events. The document will support the concept, proving that the sealant is more than adequate as a thermal barrier, a fume suppressant, and a fireblock. After all, if a high-end sealant is designed to stop air and tiny vibrations, the odds are it’ll be able to block any wisp of smoke.
As apartment block, office buildings, and homes are designed by architects with firewalls in mind. The addition of a chemical sealant that can reinforce this flame retarding ethic is to be commended. Additionally, these foam sealants are particularly adept in the home, but imagine variations of the product being applied to vehicle engine compartments, to aircraft frames and other structures as a highly effective heat segregating agent.
