According to the people at Synthetic Ice USA:
Quote:
When you skate on ice you are actually skating on water because the blade is causing friction which generates heat and melts the ice. With Super-Glide™ the blade causes the same friction and heat, but this now causes a release of the lubricants integral in the chemical make-up of the core substance in the Super-Glide™ skating surface. This is what sets us apart from the competition. With silicone based products, like our competitors use, the blade cuts through the silicone and hits dry spots which cause the blade to give the skater a "chattering" feel. This also increases the friction, making skating more difficult. This problem is exactly what led to the scientific development of Super-Glide™ and it's unique formulation which eliminates the "chattering" and allows the blade to glide smoothly at all times.
