摘要：
This study conducted friction experiments of three elastomer block materials on ice (low pressure injection of polyurethane (PU), injection moulding of a thermoplastic polyurethane (TPU) and vulcanization of rubber (RU)), with a linear tribometer operating under four different ambient air temperatures (-10 to 0 degrees C) and six different sliding velocities (0.3-5 m/s). At low temperatures (-10 degrees C and-5 degrees C), the RU material showed the highest dynamic and static friction. However, at high temperatures (-2 degrees C and 0 degrees C) the PU revealed the highest dy-namic friction and highest static friction at 0 degrees C. We discuss the physical phenomena's of elastomer friction on ice and in relation to the application of footwear slipping on ice.
