Sliding on Ice

#PolarSkin PolarSkin Ice Sheets work for the same reason you can slide on ice. Sort of. Water is a phase change material with a melting point of 32F. Just above this, at 33F, it's a liquid, and just below at 31F it's a solid. Elementary science? Nope

Sliding on ice becomes less of an issue as the temperature falls well past 32F. Why? First, assume that an object (let's use a tire) is the same temperature as the snow and ice. As the tires pass over the snow and ice you will feel a certain level of traction occurring. As the tires continue to to rotate, the tire temperature begins to rise. At 33F the tire begins to melt the snow and ice as the tire passes over the snow and ice. This melting causes a thin layer of liquid H2O to form. Now it's slick. Only a thin film of liquid H2O interfaces with the tire and the ice. This film of liquid will remain at 32F until one of two things occur.

  1. The tire releases enough thermal to fall below 32F.

  2. The ice absorbs enough thermal energy from the tire to melt all of the ice.

PolarSkin behaves fundamentally in the same way. The PolarSkin Ice Sheets incorporates four different phase change materials with unique melting points . This allows the Ice Sheet remain at a prescribed temperature for longer periods of time. Once the first phase change occurs with the PolarSkin Ice Sheet the material absorbs energy sensibly until it reach the next melting point of the Ice Sheet.

Wishing everyone a Happy New Year! Russ #beattheheat
