Synthetic ice is a solid polymer material designed for skating using normal metal-bladed ice skates. Rinks are constructed by interlocking panels. Synthetic ice is sometimes called artificial ice, but that term is ambiguous, as it is also used to mean the mechanically frozen skating surface created by freezing water with refrigeration equipment. Comparison with true ice Skating on natural ice, the skate blade increases the temperature of the microscopic top layers of the ice reducing drag and causing the blade to glide on top of the ice. On synthetic ice rinks, liquid surface enhancements are common among synthetic ice products to further reduce drag on the skate blade over the artificial surface. Most synthetic ice products allow skating without liquid. With most synthetic ice products, more effort is required to skate. Although this side effect can be positive for resistance training, skaters report to miss out on the fun of effortless skating. Synthetic ice surface wears out skates much faster.Most synthetic ice products still wear-down the skate blades very fast, with 30 min - 120 min the industry average. Many synthetic rinks produce a large amount of shavings and abrasions - especially if the material is extruded sheet. Sinter pressed material on the other hand uses a much higher molecular weight resin and has a far better abrasion resistance and therefore the shavings are greatly reduced. Although this disadvantage is less on a practical level than on an aesthetic level, surfaces have to be cleaned more regularly with an extruded product and the attractiveness of the rink can be reduced significantly. Temporary markings for hockey or other sports wear off. Only permanently embedded markings do not scratch off. Materials A typical synthetic ice rink will consist of many panels (usually in typical building material sheet sizes) of thin surface material assembled on top of a sturdy, level and smooth sub-floor (anything from concrete to wood or even dirt or grass) to create a large skating area. The connection systems vary. A true commercial joint connection system can be installed virtually on any type of surface whereas the typical "dovetail" joint system requires a near perfect substrate to operate safely. The most common material used is HDPE (high-density polyethylene), but recently UHMW-PE (ultra high molecular weight polyethylene) is being used by some manufacturers. This new formula has the lowest coefficient levels of friction at only 10% to 15% greater than real ice. Usage Synthetic ice rinks are sometimes used where frozen ice surfaces are impractical due to temperatures making natural ice impossible. Synthetic ice rinks are also used as an alternative to artificial ice rinks due to the overall cost, not requiring any refrigeration equipment.For pleasure skating, rinks have been installed indoors at resorts and entertainment venues while newer installations are being made outdoors. For purposes of ice hockey, synthetic ice rinks are typically smaller, at about 50 feet (15 m) by 50 feet (15 m), and are used for specialized training, such as shooting or goalie training.
