In the past few decades there has been a gradual development and increase in the use of tile. Vinyl floor tile and asphalt floor tile can use as much as 30 to 50 per cent, by weight, of asbestos shorts and floats.

Sometimes, longer fibers are used; however, it is rare inasmuch as they are more expensive and tend to interfere with producing smoothly surfaced tiles. Asbestos is also used in the manufacture of synthetic resin tile.

It has been reported that the asphalt tile industry had its beginning in 1920 when the asphalt roofing manufacturers attempted to develop a material similar to slate shingles. The material developed was not suitable for shingles, but it started the asphalt floor tile business.

The term tile generally identifies tiles using asphalt materials as the principal binder; such organic resin binders as vinyl are used too, because they permit the manufacture of light-colored products. Vinyl asbestos tile competes with asphalt tile.

Both of these markets are expanding, however, the vinyl market is expanding faster. [That is to say, asbestos-based floor tile markets were still significantly expanding in 1959 - Ed.] Asphalt tile was originally manufactured with heavy asphalt solutions mixed with a very high percentage of asbestos filler. The tiles were hardened by means of solvent evaporation in the production process of asbestos tile production line. Hot mixed asphalt solutions were also used. These tiles were black or extremely dark in color. In order to obtain a different color, brown or intermediate colors, gilsonite is used.

Similar to asphalt tile, but generally more flexible, vinylasbestos tile has the largest volume of sales of the vinyl flooring family. The annual production rate is estimated at more than 80 million sq yd; the tile produced is usually 9 in. by 9 in. and 1/16 in. thick. Commercial installations usually use 1/8 in. tile.
