History
The first known application of plastics as a substitute for ice for the purpose of ice skating was in the 1960s using materials such as polyoxymethylene plastic which was developed by DuPont in the early 1950s. The polymers used at the time had some significant shortcomings. The most obvious being that skaters could not glide on these surfaces as they can on real ice without the regular application of a silicone compound. The compound would build up on the surface, collecting dirt and grime.
In 1994, High Density Plastics launched the first full-size synthetic skating floor under the trade name of Hi Den Ice. The surface was made of interlocking panels of high density polyethylene which became an ice rink when sprayed with a gliding fluid. The surface needed to be cleaned off and resprayed once a month. In a dry form, the panels were also usable for other indoor sports.
Research and development in the field of synthetic ice has improved its skating characteristics. Special polymer materials have been specifically engineered for skating and unique lubricants designed to work with the polymer and be absorbed by it so that the surface is less sticky and does not attract contaminants while providing an ice-like glide. Smoothness between panels at seams has been improved by improvements in production and assembly methods. It is estimated that synthetic ice has 90% of the glide factor of natural ice.

Famous quotes containing the word history:
“the future is simply nothing at all. Nothing has happened to the present by becoming past except that fresh slices of existence have been added to the total history of the world. The past is thus as real as the present.”
—Charlie Dunbar Broad (1887–1971)
“The history of work has been, in part, the history of the worker’s body. Production depended on what the body could accomplish with strength and skill. Techniques that improve output have been driven by a general desire to decrease the pain of labor as well as by employers’ intentions to escape dependency upon that knowledge which only the sentient laboring body could provide.”
—Shoshana Zuboff (b. 1951)
“What we call National-Socialism is the poisonous perversion of ideas which have a long history in German intellectual life.”
—Thomas Mann (1875–1955)
