ATM mats are made of super-thin BSTV basalt fibers, lined on all sides with glass or silica fabric and stitched with appropriate threads.
Dimensions
Length – 1100mm
Width – from 500 to 800mm
Thickness – from 5 to 60mm
Sizes of mats can be agreed.
ATM mats are used as a highly effective heat and sound insulation insulation. They are characterized by heat resistance, incombustibility, high chemical resistance to alkaline and acidic environments, and a high sound absorption coefficient. Do not contain a binder.
An exceptional feature allows the use of ATM mats with very high vibration and cyclic exposure to temperature, while the characteristics and geometric shapes remain unchanged, which allows them to be used repeatedly as removable insulation.
Scope and features of application
- Use as a noise-reducing, sound-absorbing and heat-insulating material for industrial equipment, apparatus,
Vehicle. - Use in the construction industry (thermal and sound insulation of industrial, civil and individual construction objects).
- Application as a heat and noise insulation layer on vibrating equipment of nuclear power plants and thermal power plants.
