Asbestos products & applications: what types of products were made using asbestos, and what were the various industrial and private markets for asbestos materials? This article gives the history of and describes the various applications of use of asbestos. We include an original table listing the wide range of asbestos-containing products across all areas and uses, and we link to a newer, more complete list of asbestos products & materials.
This articles series about the manufacture & use of asbestos-containing products includes detailed information on the production methods, asbestos content, and the identity and use of asbestos-containing materials. Our page top photo shows asbestos hardcast or paste insulation used on the exterior of a heating boiler.
Basic and applied research and development programs
have been carried out for many years on asbestos materials
and their products. The consumption and sales of asbestos
as well as the diversity of its applications have been

New mine deposits have been located
and improved mining processes have been discovered.
in turn have stimulated new product development. The
future growth of the industry may be estimated from
an analysis of the items in Table 1.7.
Asbestos products are
important contributors to the comfort and safety of mankind;
they are also important base materials for our
highly scientific and space age.
Materials exist for insulating
the home, operating automobiles, reducing or eliminating
fire hazards in industry and at home, protecting buildings,
pipes and other items against corrosion and decay; the same
materials service blast furnaces and steel mills, permit operation
of and provide protection in electric power stations, provide
fire resistant products on hoard ships, and help in the
development and progress of missiles and aircraft.

Asbestos in Building Construction
Asbestos-cement products are
widely used in commercial and industrial buildings and
Such products utilize the largest quantity
They include siding and roofing shingles, flat
and corrugated sheets, and wall boards, all of which are now
available in many different decorative colors.
Within recent years  approximately one-half of all asbestos
used in the United States was employed in the manufacture
of asbestos-cement sheets, pipes and floor tile.
Another important item is millboard. This product is similar to cardboard in appearance but is much tougher and stronger.
Incombustible insulation boards are available in different
colors. Another building material is asbestos-felted roof insulation;
this material is generally combined with asphalt.

hot spots—furnace repair, coking, working white hot ingots, etc.

Asbestos filled plaster, stucco and paints provide fire resistance
with low maintenance and good appearance.
In the hard-surface floor covering industry, asphalt and
vinyl-asbestos tiles (ASBESTOS FLOOR TILES) have helped to build a major industry.
Now they account for approximately 29 per cent of the flooring
The original textile use of asbestos was
in such woven products as coats, aprons, shoes, and gloves.
Next came asbestos curtains for the theatre and for other
public buildings. Now the textile uses are indeed diversified.
These uses include fire blankets, iron rollers, electrolytic
cells, filters, linings for ovens and refrigerators and oven or
As illustrated by our photo, asbestos textiles were also widely used in HVAC systems to provide flexible, heat-resistant connections between the air handler and ductwork, functioning as a vibration dampener to avoid sending equipment noises into the building. See ASBESTOS DUCT VIBRATION DAMPENERS.
Asbestos cloth continues to play an important part in the
manufacture of woven brake linings, clutch plates, and
related friction products.
Asbestos yarn and cloth are important as reinforcing
agents or fillers for gaskets and packings. Such diversified
types of hinders as organic and inorganic resins and rubbers
are used with asbestos to provide products which are resistant
to high temperature, to chemicals, to high pressures and
Asbestos is incorporated in filters (woven or nonwoven
form) and it is used to filter such products as dust, chemicals,
blood, and viruses.
Asbestos Use in Heat Insulators
Asbestos fiber is used alone or in combination
with other materials to produce temperature or
electrical insulations. The heat insulators can be used to
conserve fuel, eliminate overheating of areas, or protect
other products from fire.
Such varied types of heat, insulators
as millboard, molded shapes for pipes, other heat-generating
units, and different grades of paper are manufactured.

Insulators for heat and sound generating units are made
so that they provide maximum efficiency in these applications.
These types of products contain a very small percentage
of binder. Insulating material is also applied by spraying.
Asbestos filled inorganic binders are predominantly used.
Asbestos paper (above left) and on occasion asbestos fabric (above right) was used to wrap the exterior of heating ducts and their connection to heating registers - Ed.. For details about asbestos cloth or fabrics or paper used in these applications see:
Asbestos filled thermal insulation is an essential part of
modern equipment in most manufacturing plants. Such insulation
applies to boilers, pipes, reactors, etc.

plants may use asbestos electrical insulation on many of
their cables and wires. This is clone so that when cables are
overloaded and/or subjected to extreme high temperatures,
the asbestos fiber will occupy space with relatively no loss
in density or bulk.
Where high electrical insulation value is required and
extremely thin paper products are required, asbestos
products find good application. Extremely thin paper
sheets which are composed of nonmagnetic contaminants
Some general applications of asbestos products in the
electrical industry include conduit coverings, spark arrestors,
battery boxes, armature windings, bus bars, motor
slot wedges and other parts requiring good electrical properties
and high temperature resistance.
Asbestos Use in Motors and Engines
Nonwoven asbestos is extensively
used in brake linings, clutch facings, packings, and gaskets.
Asbestos filled plastics have found applications in such
varied automotive or motor parts as heaters, electrical units,
bearings, washers, etc. Such varied fillers as metals, graphite,
sisal, and glass, in addition to asbestos are frequently used.
Typical mass produced asbestos filled phenolic parts are
distributor covers and rotors.
Another application for asbestos is in lubricants to give
solidity and to regulate the melting temperature or the rate
