Cloth gasket


TOMBO™ No. 1374/13781420-ST/-S/-TH/1400-NA9094

An endless gasket in which woven fabric is coated in a rubber compound and sewn together into various manhole shapes. This gasket has insufficient airtightness, so use it only for parts where some slight leakage is permitted.
It is best suited for applications in which the flange diameter is large, there is distortion, or a high clamping surface pressure will not occur.

Heat-resistant rock wool heat-insulation material with moisture-proof barrier

MAKIBEE™ dannetsu

TOMBO™ No. 5520-D

“Is there a thermal insulation material out there that is resistant to fire and has a low thermal conductivity?”
“Can you improve its fire resistance as well as its thermal insulation?”
“Spray-on thermal insulation materials have inconsistent thickness and we struggle to ensure thickness-related consistency”
MAKIBEE™ dannetsu is a thermal insulation material born out of such customer feedback. For the base material, rock wool with heat resistance equivalent to MAKIBEE™ is used.

Square stack lining material


TOMBO™ No. 6496

CERASTUCK is a board-shaped stack lining material with excellent heat resistance and workability. It is made by adding aggregate and inorganic reinforced fibers to its main material Xonolite (calcium silicate). It can be used for the exhaust of boilers for distributing hot water and heating as well as the exhaust of internal combustion engines of home power-generation facilities.

Board-form heat-insulation/sound-absorption material


Nichias offers two types of MG BOARD: a JIS1 product (MG BOARD 080) and a JIS2 product (MG BOARD 120), which are made by adding a thermosetting resin to rock wool as a binder and molding it into a board. For the surface materials of MG BOARD 080, Nichias offers adhesive aluminum glass cloth (ALGC) and glass cloth (GC) that is affixed flat on top and around the edges.

Belt-shaped thermal insulation materials


MG BELT is made by cutting MG BOARD into strips and reinforcing it with cheesecloth.
The fibers stand upright in the thickness direction, and so it has excellent flexibility and is easy to wrap around pipes and circular ducts. Nichias’ product lineup also includes a cheesecloth-affixed product and an ALGC-decorated product.

Roll-form heat-insulation/sound-absorption material


MG MIGHTY ROLL is a product in which minute amounts of resin are added to rock wool as a binder before molding it into a felt. ALK (aluminum craft foil) or ALGC (aluminum glass cloth) is then affixed to one side before rolling the product up into a roll.
The adhesive ALGC products comply with the Japanese Architectural Standard Specifications (Mechanical Equipment Construction Work Edition).

Blanket-form heat-insulation/sound-absorption material


MG WIRED BLANKET is a product that is made by fixing hexagonal wire mesh to one side of an MG BOARD with iron wire and rolling it up into a roll.
It has excellent workability and can be installed easily onto complex parts and curved surfaces. It is also useful as an additional heat insulation material for added thickness.

Rock wool pipe heat-insulation material


MG MIGHTY COVER is a roll of lightweight heat insulation material that is not susceptible to bending and has excellent thermal insulation, heat resistance, and non-flammable properties.
It has low levels of halogen and so it is excellent at preventing stress and corrosion cracks in stainless steel.

Decorated rock wool heat-insulation material

MG Decorated heat-insulation material

MG Decorated heat-insulation material is a product that is made by affixing ALGC or ALK on the surface of an MG product.
It comes complete with an outer material, so the finish is aesthetically pleasing and it is easy to install.

Decorated rock wool sound-absorption material

MG Decorated accoustic material

MG Decorated acoustic material is a sound-absorption material that is finished by adhering glass cloth around all sides of MG BOARD.
It is a product suitable for indoor sound absorption such as in underground machine rooms.

Reusable flexible heat-insulation material


TOMBO™ No. 4500-R

It is an attachable thermal insulation material that can be used repeatedly.
Nichias assists in environmental conservation and improvements through energy saving initiatives at buildings and plants.

Fluoropolymer slide bearing material


TOMBO™ No. 9017

Various slide bearing pads (sliding pads) are used to absorb the expansion and contraction that occurs in structures such as bridges or corridors between buildings.
NAFLON™ Sliding Pad, which uses filler-filled fluororesin (PTFE), is superior to conventional rubber pads, metal plates, roller bearings, etc. in many aspects such as low friction, high weather resistance and chemical resistance.
