In the world of E-cars There is a new development. The rolling noise of the tires is much more present in electric vehicles, as the engine works almost silently. To counteract this, tire manufacturers have in the past relied on so-called Silent Tires leave.
These are tires that reduce driving noise through special materials and a special design. However, the technology has so far been expensive and difficult to produce.
Handle & 4JET
But Henkel (known from brands like Persil or Schwarzkopf) has together with the laser specialist 4JET a possibly groundbreaking solution is on the way. Until now, a quiet tire has been Polyurethane foam which dampens the noise. However, the effort is usually around 25% more expensive for the end customer. But the new process is more effective.
No solid foam is used, but liquid acoustic foamIt is placed directly into the tire at the end of the production line and is activated using a patented laser process from 4JET. The so-called Direct foam to tire technology is faster, cheaper and even more environmentally friendly.
The technology behind the innovation
The heart of the Loctite LASER-FIT acoustic foamIt has a specially designed pore structure that absorbs sound waves instead of reflecting them back. The laser process removes the skin of the foam, allowing full sound absorption. What makes the system particularly impressive is the speed with which it was developed.
From the first performance at the TireTech in Hanover until the final premiere at the upcoming RubberTech24 in Shanghai It's only six months. With the new tires, electric cars could soon become even more comfortable and quieter. Source: Henkel
