There had already spoken before the Singapore Grand Prix on the use of Polysil the rims to try to bring to the correct temperature in a short time the tires Discovered the material used inside of the rims: It called Polysil. The images seen today in the pits of Korea we can see that Ferrari uses this material that is produced by a company in Sassuolo called Nanoprom. The material used is a kind of liquid glass with black opacifying pigment that is used to improve the thermal conductivity and it is created primarily for the market for the nautical. It is a based on atomic silicon coating with revolutionary features that allows the protection of reconditioning the substrate surface structure. With a layer of a few microns high surface hardness (9H) ,the surfaces also have a high resistance to abrasion. This “liquid glass” weighs 95% of a normal painting and has a resistance to temperatures of 1100 ° C. Currently the color coatings of a wheel of Formula 1 weigh from 65 to 85 grams. Thanks to this product the coating weighs only 5 grams and in addition to improving thermal conductivity gave an improvement of 3 points to the CFD as are generated less turbulence.
