Specializing in Dry Ice BlastingThe Polar Clean Story
Dry ice creates a micro-thermal shock upon impacting the contaminant on a surface, because of the extreme cold (-109.3 F or -78.5C). The cold temperature makes the material brittle, shrinks the material, and loosens it from the subsurface.
The solid food-grade dry ice pellets strike the cold and brittle contaminant and fractures it. The energy transfer begins to remove the contaminant without abrasion to the substrate surface.
When the dry ice comes in contact with the warmer sub surface, the dry ice converts back into carbon dioxide gas, a process called sublimation. This process results in the dry ice getting into the fractured contaminant and expands 800 times in volume, lifting the contaminants from the surface.
