What is the Polysil on the rims of the F1 wheel
Is called Polysil, It is a product of NANOPRO, company of Sassuolo and it is a film that allows trattene the heat of wheel rims and then return it to the tires by improving the thermal warm-up of the tires.
During the World Cup Formula 1 2013 has talked a lot about this issue but now we are able to show a video, posted on facebook Gian Luca Falleti, owner of the NANOPRO, in which the same company, for voice Giorgio Falleti explains their product.
The Polysil has the ability to attract and transmit heat to himself then in the wheel rims. For every braking action on a F1, thanks to Polysil, generated from the brake disc temperature it is stored and transmitted to the rim which in turn will distribute it inside the tire. So out of a bend the tire itself will be warmer and better trazionerà seater.
The teams that have used the drug were three: Ferrari, Mercedes e Red Bull.

Read MoreSport polish, nanotechnology anti marbles
The Nanoprom product is called Sport polish and has been used by two Formula teams 1 to Interlagos. The ingenious club from Sassuolo that came to the fore for Polysil, the film of “liquid glass” which allows to retain the heat of the rims and return it to the tires, improving the warm up of the tire, in its catalog it offers other very interesting nanotechnologies that have piqued the curiosity of two Circus teams.
The bodies of four single-seaters in Brazil have been treated with Sport polish, an anti-adhesive product that has given excellent results to prevent the rubber marbles from occluding the blowing in the front wing flaps, also ensuring effective protection from oil and insects.
The teams were also able to count on two other products: EcoBio1000 and Nanopulitore 602. The former made it easy to clean up residues of hydrocarbons or other impurities on the bodywork. It is a solution that was designed for airplanes (it is used by the helicopter team of Turin and by two companies within Linate airport). The second one, instead, has the ability to remove the protective products released by Sport polish and EcoBio1000 products, as well as removing dirt in depth, leaving the surface ready for painting, without further steps of detergents and degreasers.
Nanoprom technicians assure that compared to normal silicone products, or with naphtha inside them, you can get surprising results with Sport polish since the reduction of dirt adhesion is 80 percent compared to more traditional solutions. Not only, but the other products on the market need to be treated before each session on the track, while the Sport polish only needed one intervention before free practice on Friday and it proved to be sufficient for the whole Brazilian weekend. There remains only a doubt: which teams have benefited from nanotechnology? For now the names remain top secret ...

Read MoreLatest end-of-season questions: technical tricks and originality
with F1, In the foreground / by Anna Re / the 17 November 2013 all 19:14 /
Penultimate test session at the Austin circuit: we will see who studied well, apart from that nerd Vettel. Promoted, postponed and rejected among the "students" in competition. Opposite is a winter of intense and restorative study ...
From today, only one weekend separates the Formula teams 1 from the bell at the end of the F1 World Championship 2013. The FIA for the winter holidays did not fail to "impose" the dictates according to which to develop the car 2014. According to the new regulation, the single-seater cannot be developed (inserting or removing new components) during the four test sessions to be carried out during the season, approved for the championship 2014. A restriction that has a direct consequence: the teams will have to present the car on the track with the new components already installed, without being able to evaluate improvements or comparisons between different configurations during the test sessions.
For this reason, several teams use the latest races of the 2013 as test sessions, without giving up the maximum performance of the car in the current race.
Red Bull hasn't made any aerodynamic changes, but experiment with Polysil on circles (amorphous solid similar to liquid glass, with black mattifying pigment, used to improve thermal conductivity) with the intent to speed up the heating of the rims and keep the heat distribution constant. Mercedes experiments with new paints, to study the effect on aerodynamic flows. Williams and Sauber have modified the exhausts thus obtaining amazing performances (Valtteri Bottas not, Nico Hülkenberg room), but without making substantial changes, but by proposing solutions from the 2012.
Lotus will race with both single-seaters suitable for the Texan track, but already changed in perspective 2014, with the long wheelbase (wheelbase longer than 10 centimeters), the configuration preferred by Roman Grosjean and with an open air vent near the upper attachment of the rear suspension. The Ferrari reads everywhere about "monkey seat", "Front wing with upper flap", "Bridge side deflector" (we wrote it too): only to pronounce them would one have to enroll in a university training course, with personal assistant ...
The Circuit of the Americas requires more downforce: this is the purpose of the monkey seat and makes his debut in the car from Maranello at the Bahrain GP 2012. It is a very small aerodynamic appendage installed on the lower support of the rear wing, with the aim of directing the heat by improving the interaction of hot air that goes from the hood to the rear wing. The monkey seat in the final part of free practice was eliminated from Alonso's F138.
The front wing is designed to generate aerodynamic load and also to manage the air flows to direct the flow along the body of the car and minimize resistance to forward movement, decreasing the amount of air that impacts on the tread. This is the purpose of the front wing: the one mounted on Massa's car is that of the Singapore GP, the front wing with two blowholes on the top was tested on the Alonso car (upper flap), a solution inspired by Red Bull.
Finally, the bridge side deflector - used only in Abu Dhabi - has the purpose of directing the flow of the sides towards the final part. Lift decreases thanks to the particular "P" structure that flattens the flow, obtaining greater adherence to the car body in the lateral area. Another effect is to stabilize the car in the event of side gusts.
A solution used in practice sessions, but then eliminated in both cars for qualifying. We will see how much the "Allison cure" in Ferrari - with its assemblies-and-disassembles - will be able to reinvigorate hopes for second place in the constructors' classification.
All that remains is to wait for the 20 for the exam session: all on the starting grid ready for questions! Ballots later 56 laps ...

Read MoreF.One – Tecnica, the Nanoprom launches Q.R.S for hoops!
After providing the all'OZ Racing Polysil, the silicon film formed by nanotechnology that allows to retain the heat of the circle with the goal of immediately send heat into the tires in the first lap of each stint (qualifying and race), the Nanoprom, company of Sassuolo, He has already designed an interesting evolution of the theme: il Quantum Radial System. So far the engineers have worked only in the outer face of the rim, but inside the channel, making sure that the heat generated from the brake to dissipate (the wheel comes to temperature peaks which reach the 200 degrees) avoiding that there is disposal quickest possible thanks to the special ducts. With the current Pirelli tires circle has taken a secondary function that Gp Gp after gaining increasing importance.
GLASS LIQUID The application is simple: spraying the "liquid glass" in the circle and creating a film of a few microns (touch does not feel any step between the treated and the "naked") that, in addition to ensuring a limited thermal conductivity, associates high abrasion resistance thanks to the surface hardness of this material which also offers a small aerodynamic advantage since it reduces the turbulence generated in the circle for the rotation of the wheel. Without forgetting that the traditional coating of a wheel F.1 requires at least 65 grams of paint, while it only takes Polysil 5 grams!
NANOPROM FORGE OF IDEAS Now the genius engineers to Sassuolo of Nanoprom directed by Gianluca Falleti studied a new treatment that is aimed at increasing the temperature on the inside of the circle: exclusive image that we propose, indeed, We see the Quantum Radial System that has been sprayed with the power to have a high thermal conductivity. The Opposite of Polysil! The tests carried out have shown a marked improvement of the "warm up" in the circle and consequently of rubber. Also in this case we have been used of nanotechnology (some people think that you are also materials for aerospace and military nature!) but without having as a starting silicon.
THERE 'S ONLY THE POLYSIL What is it? For now, the curiosity of Q.R.S. can not be satisfied, because the new material is still top secret, but are different teams of Formula 1 who have already shown a great interest in this innovation throughout Italian. What is the temperature rise that can be drawn from this treatment? The experiments are initiated with a gain of five degrees, but tests conducted later are leading to more meaningful values, especially since it would be possible to generate more heat when the designer needs it most.
MANUFACTURERS CONCERNED short, the feeling is that the Nanoprom not want to be a company that wants to limit to only offer revolutionary products, but also it has the ambition of becoming with its engineering consultant Manufacturers, to develop other applications that can provide performance benefits to the cars that represent the ultimate expression modern technological ...

Read MoreA special coating for wheels controls the temperature of the tires
Enzo Ferrari asserted that the English manufacturers should not claim the title of builders in when they did everything in the house but bought the components from the best suppliers on the market using the name of garage owners. The old Drake also knew that with the mechanical changes you earn tenths but with the tires working well you can recover even the seconds. In any case, even a total manufacturer like Ferrari and Mercedes has to deal with some components that necessarily have to buy. The tires and rims on which calettano. The difference is also in choosing the best suppliers that offer the best material and the best possible technology.
All this to explain that it is the Mercedes but also the Redbull then used a special surface coating for the 'inside their circles. As seen in the photo to the left is a circle with a black Mercedes with fins and right to RedBull with a black jacket the same but with a series of small dimples. This coating was created by an Italian manufacturer the Nanoprom, and it is a paint based surface of a component called Polisyl. In practice it is it is a surface coating which protects the surfaces which wear out by atmospheric agents and also used on boats clearly improves the penetration in the water for reducing friction it is said that this paint is also used for the bodywork of the Redbull to improve the aerodynamic penetration.
Use this product on a circle by formula 1 It has the functions to stabilize and increase the flow of warm air from the brakes into the circle itself to the outside by straightening the turbulence in that area huge gift. A controlled flow inside the wheel also allows to keep under control the temperature of the magnesium wheel. Since magnesium is an excellent thermal conductor, the heat is transferred directly to the tires with all the damage that you know. It goes without saying that control the flow vortex can not also allow teams to have the circles in desired temperatures to make the circle as a kind of blanket inner race running as needed.
The thermal room photo, shows how the RedBull uses this protective coating and dimples to keep the internal temperature constant cornering removing faster hot air to the outside. As seen in the images above, a curve faced by Vettel in Austin to the temperature curve input is greater that in the final phase of the curve where it should be higher for the effort in curve. But the amazing thing is the use of this paint on the straights as seen in the lower part of the picture with tire warm even on the obverse. Combined with Lemelle and dimples air flow can be controlled in its elimination or stagnation. If you can control the flow velocity of the hot air from the brakes are held hot wheels even on the long straights. It is saying that if a circle remains warm even the rubber that remains above is kept hot and into the corner you have the ideal temperature while the other Ferrari in the lead coming into the curve on cold tires with a noticeable loss of grip and then warm too much not being able to control the temperature in the middle curve. Such a system as simple as it can also bring advantages in terms of lap time even of the order of eight tenths in certain tracked. In fact if we go back to the speech starting work with the tires Pirelli earns much more than any mechanical or aerodynamic devilry. The fact that this company is in the Nanoprom Emiliana land and its beneficial effects discovered them first in UK from companies like Mercedes and Red Bull, It speaks volumes about the fact that it makes no sense to build everything yourself then if you neglect certain details that make a huge difference.
