Successive Launch of Four New Products for Fireproofing Service Penetrations of Compartments
- Contributing to needs and convenience on construction sites by providing a diverse range of products -
The Furukawa Electric Co., Ltd., and Furukawa Techno Material Co., Ltd. (Headquarters: Hiratsuka, Kanagawa Prefecture; President: Toshio Tosaki; Capital: 300 million yen, 100% funded by Furukawa Electric) are successively launching four new products in the form of materials and fire proofing measures for cables and piping that penetrate walls and floors in fireproof compartments installed inside buildings. By providing a group of diverse products, we are working to improve convenience for users while responding to construction site needs.
The products will be shown at the 61st Electrical Construction Equipment and Materials Fair (JECA Fair 2013), which is held from May 29th to 31st.
- DANSEAL-KP, a lightweight fireproof putty
- ICHIJIKAN Pat, a fireproofing method for circular holes in walls (electric wiring)
- ICHIJIKAN Maruyuka, a fireproofing method for circular holes in floors (electric wiring)
- ROKUMARINE-TIGHT, a fireproofing method for airtight, watertight walls and floors (marine wiring)
By law, wherever cables or wiring penetrate the walls and floors of fireproof compartments installed in given areas in buildings and ships, it is obligatory to install fireproofing measures with a fire-resistive performance of one hour accredited by the Minister of Land, Infrastructure, Transport and Tourism in the case of buildings, and fire proofing measures with a fire-resistive performance of 1 hour accredited for ship classifications worldwide in the case of ships.
As a pioneer of fireproofing measures, Furukawa Techno Material Co., Ltd. has provided a range of materials and methods of construction over a quarter century. Recently, building specifications and needs at building sites have been diversifying, and there is a demand for methods and materials that can be adapted to various types of constructions. In addition, the job is made easier when the construction is uncomplicated and the structures are simple and lightweight, which increases convenience for the contractor. Therefore, we have now expanded our lineup with new materials and new construction techniques for both construction use and marine use, including DANSEAL-KP, a newly developed lightweight and fireproof putty. These materials are either pending, or have passed official fireproof testing to obtain accreditation, and are expected to go on sale in order of precedence.
DANSEAL-KP is a unique, lightweight and fireproof putty recently developed by Furukawa Techno Material Co., Ltd. Since conventional fireproof putty is required to withstand flames and retain its shape, it is heavy with high specific gravity (1.8-2.0) as it contains a lot of inorganic filling material. The newly developed DANSEAL-KP demonstrates excellent fire resistance even though, at 1.0, it has only about half the specific gravity. It is soft with outstanding workability; it is both easy to transport and to install because of the light specific gravity; and it is also economical because a larger volume of the material can be used without adding weight. Since the putty does not harden, maintenance and rebuilding after installation is also easy. It can be used in many places including fireproof seals for service penetrations in fireproof compartments, places that require anti-smoke partitions or flame resistance, or to finish gaps between joints etc.
ICHIJIKAN PAT is a process that simplifies construction where electric wiring penetrates the walls of fireproof compartments in buildings. After filling gaps in the opening with DANSEAL-KP, the installation is completed by simply wrapping the service penetration in flexible and thermally expandable Rokumaru Sheets. For openings up to a maximum diameter of 160 mm, it can also be applied to service penetrations with cables and flexible plastic conduits, or a mixture of the two. It can also be applied to a wide range of walls including concrete walls, ALC (Autoclaved Lightweight Concrete) walls, hollow plaster walls, and thin walls, and by using a steel sleeve it can also be installed on one side. We have obtained accreditation by the Minister of Land, Infrastructure, Transport and Tourism, and at present, we have passed official tests that have expanded the scope of application. We are also applying for accreditation by the Minister of Land, Infrastructure, Transport and Tourism for the expanded applications, as well as a rating for condominiums and other residential quarters by the Fire Equipment and Safety Center of Japan.
ICHIJIKAN Maruyuka is a process that simplifies construction above floor level where electric wiring penetrates the floors of fireproof compartments in buildings. After inserting the auxiliary support fittings and backup materials in the gaps in the opening, the installation is completed by simply filling with DANSEAL-KP to the level of the floor. For openings up to a maximum diameter of 160 mm, it can also be applied to service penetrations with cables and flexible plastic conduits, or a mixture of the two. Since it is finished with putty, the presentation and seal properties are good; it copes with minor water leaks; and it can even be applied to protruding steel sleeve conduits installed in the floor. We have passed the official tests and are presently applying for accreditation by the Minister of Land, Infrastructure, Transport and Tourism.
Rokumarine-Tight is a process for combining fire resistance with watertightness and airtightness where electric wiring penetrates a ship's bulkhead and deck (floor). The installation is completed by closing the opening with Rokumarine-Tight Light Sealant, which is a sister product of DANSEAL-KP, and filling it in with a pourable quick-hardening material made by mixing Rokumarine-Tight Hardener with water. Water pressure resistance is 0.25MPa/60 minutes, air pressure resistance is 0.03 MPa/60 minutes, fire resistance is 60 minutes, and we have obtained accreditation by Nippon Kaiji Kyokai. The process can be applied to combing openings (rectangles) up to maximum 300x800 mm, and to SGP openings (round) with a maximum diameter of 200. This process has been developed jointly with Furukawa Electric Industrial Cable, Co., Ltd., which also handles sales.
