 tiles are composed of colored vinyl chips formed into solid sheets of varying thicknesses (1/8” is most common) by heat and pressure and cut into 12” squares. Tiles are applied to a smooth, leveled sub-floor using a specially formulated vinyl adhesive
Adhesive
An adhesive, or glue, is a mixture in a liquid or semi-liquid state that adheres or bonds items together. Adhesives may come from either natural or synthetic sources. The types of materials that can be bonded are vast but they are especially useful for bonding thin materials...

 that remains tacky but does not completely dry. Tiles are typically waxed and buffed using special materials and equipment.

Vinyl tile is favored over other kinds of flooring materials in high-traffic areas because of its low cost, durability, and ease of maintenance. Vinyl tiles have high resilience to abrasion and impact damage and can be repeatedly refinished with chemical strippers and mechanical buffing equipment. If properly installed, tiles can be easily removed and replaced when damaged. Tiles are available in a variety of colors from several major flooring manufacturers. Some manufacturers have created vinyl tiles that very closely resemble wood
Wood
Wood is a hard, fibrous tissue found in many trees. It has been used for hundreds of thousands of years for both fuel and as a construction material. It is an organic material, a natural composite of cellulose fibers embedded in a matrix of lignin which resists compression...

Vinyl composition tiles took the place of asbestos

Asbestos is a set of six naturally occurring silicate minerals used commercially for their desirable physical properties. They all have in common their eponymous, asbestiform habit: long, thin fibrous crystals...

tiles, which were widely used in schools, hospitals, offices, and public buildings up until the 1980s. Use of tiles and adhesives containing asbestos were discontinued when asbestos materials were determined to be hazardous. The asbestos content of tiles sometimes can be determined by size or appearance. Tiles free of asbestos cannot distinguished by their size alone – although asbestos tiles were commonly manufactured in 9-inch squares, not all 9-inch square vinyl tiles manufactured before 1980 contain asbestos, and asbestos tiles were created in a variety sizes. Mastics and adhesives containing low concentrations of asbestos were used into the 1970s and are generally considered non-hazardous because the asbestos is not considered friable.

Non-ACM (asbestos containing materials) floor tiles are not identifiable by their size. ACM flooring (tiles, sheets, panels, etc.) may come in any color or size and the use of asbestos in flooring and mastics has not been eliminated.

In the debate over the "greenness" of building materials, vinyl has become a divisive topic. Burning the material can release dioxins and other hazardous chemicals. Harmful additives such as phthalates and heavy metals can leach out of the roughly 1.5 million tons (1.4 million metric tons) of vinyl discarded each year just in the United States.
