However, due to the poor water resistance of the constituent materials, long-term safety was problematic in areas susceptible to large amounts of moisture such as rain and condensation water. Also, due to its low strength, there were problems with workability such as breakage during work.

性に劣る為、好ましくない。 Regarding the thickness of the film, if it is less than 0.01 mm, it is not appropriate because problems such as poor wrapping workability, increased moisture permeability, and decreased reinforcing properties of the strips occur. On the other hand, if it is 0.10 mm or more, there is a risk that the degree of thermal foaming of the strip will be inhibited, and it will be less reliable as a sealing material in case of a fire, which is not preferable.

It can be roughly divided into cases where polymer films are simply superimposed on each other, but the purpose of the present invention can be achieved in either case. The above-mentioned adhesive refers to a support with adhesive properties on both sides, such as double-sided adhesive tape, and
consisting of a string-like adhesive layer, and a liquid adhesive;
Also, any hot melt type adhesive can be used as long as it can stick polymer films together.

のメリツトは非常に大である。 As mentioned above, the sealing material of the present invention is a sealing material in which the side surface of the strip 2 made of a thermally foamed material is coated with the aforementioned polymer film, and protects the strip from environments such as rain and dew and condensed water. In some cases, the length of the strips is not long enough to fully perform the function of blocking hot smoke and toxic gases, which is the original purpose of the strips, and due to the reinforcing effect of the covering polymer film, Deformation and breakage are prevented, workability is improved, and at the same time, application to areas that require waterproof and moisture-proof properties can be kept to a minimum, reducing human safety and expensive costs. It is very useful in preventing damage to machinery and equipment, and has great benefits in terms of industrial development.
