From a functional perspective, the key performance indicators of intercotch composite TPU anti-slip cloth in operating room floor mat applications are as follows:

The special structural design of the material makes it outstanding in anti-slip performance. The surface layer of the TPU has been carefully textured to form a micron-level concave and convex structure, which can effectively increase the friction force of the contact surface. At the same time, the bottom of the material adopts a honeycomb airbag design, which not only ensures sufficient support but also provides a good cushioning effect. According to the clinical test report of the UK National Health Service (NHS), floor mats using this material can still maintain stable anti-slip performance under slippery conditions, and the sliding distance is reduced by more than 60% compared with ordinary rubber floor mats.

InIn terms of antibacterial properties, the inter-cotton composite TPU antislip cloth forms a long-lasting antibacterial protective layer by uniformly dispersing nanosilver ions in the TPU substrate. Experimental data show that the material’s inhibition rate on Gram-positive and negative bacteria exceeded 99.9%, and after 100 high-temperature and high-pressure disinfection, the antibacterial performance remained above 99%. This long-acting antibacterial property is of great significance to maintaining a sterile environment in the operating room.

In addition, the ease of cleaning and chemical resistance of this material are also important advantages in operating room applications.
