TOMBO™ No. 8300 FIRE PROOF CLOTH

Fire-Proof Cloth

TOMBO™ No. 8300

FIRE PROOF CLOTH

Shipyards and construction sites are constantly exposed to the risk of fires due to spatter and slag produced during welding and cutting. There may also be cases where vital equipment such as computers could be damaged. Our Fire-Proof Cloth is a dedicated spark-protection cloth developed to withstand such severe conditions.

Forte

It offers excellent resistance to molten metal.
Lightweight and flexible.
It offers excellent workability.
*We also offer custom-designed sewn products. Please consult us if you have particular specifications in mind.

Application

Prevents the scattering of welding sparks
Prevents the scattering of slag when cutting
Equipment protection and covering
Non-combustible curtain

Comparison with carbon-based cloth

A test was carried out to compare the product with a carbon-based cloth that is typically used at welding sites.
Specimen
FIRE PROOF CLOTH S (Nichias product)
FIRE PROOF CLOTH SW cloth surface (Nichias product)
FIRE PROOF CLOTH SW coating surface (Nichias product)
A typically used carbon-based cloth
Test conditions and test method
JIS A 1323 Class A equivalent
The four test specimen types were used to assess the flame retardancy of sparks generated when a 9mm-thick steel plate for spark generation was cut.
Judgment criteria
No through holes that are harmful in terms of ignition and fireproofing.
Test results
No through holes that are harmful in terms of ignition and fireproofing were made in either test specimen during the test (about 48 seconds long).
However, smoke was observed after the “typically used carbon-based cloth” was cut on its own.
A video of the test is below.
