Canvases made of super-thin staple basalt fiber.

TU 23.99.19-001-93378912-2021


They are layers of chaotically spaced staple basalt super-thin fibers obtained by blowing primary fibers with hot gases and bonded together by natural cohesion forces.

Designed for the manufacture of high-performance heat and sound insulation and sound-absorbing materials in building structures, as high-temperature insulation in power and industrial equipment, furnaces, heating devices, as a heat-insulating material in construction, in the construction of noise mufflers in ventilation and air conditioning installations, as filters for cleaning gas-air and liquid media and other products with specific properties due to the fine-fiber structure.

Canvases are produced in two types:

BSTF- st – basalt super thin fiber for construction purposes;

BSTF – sp – special purpose basalt super thin fiber.

Canvases made of staple basalt super-thin fibers belong to the group of non-combustible materials (NG), are environmentally friendly products, they do not emit toxic substances in the air, do not form toxic compounds in wastewater and in the presence of other substances.

Packing canvases are made in plastic wrap.

Transportation - BSTF canvases are transported by any type of covered transport that protects against moisture and pollution in accordance with the rules for the carriage of goods in force for this type of transport.
