Does foaming agent work when car tires make loud noise? Does foaming agent on fenders soundproof?

The filling of foaming agent must play a certain role in sound insulation, but foaming agent is flammable, and I think it is still a bit inappropriate to use it in high-temperature places near the engine. There are many ways to insulate the car. The simplest and most effective one is to replace the Michelin Haoyue tires, which are the most comfortable. Other sound insulation cotton and shock-absorbing glue can be used. After all, there are a lot of things to be dismantled, and there may be abnormal noises after disassembly.

What is a foaming agent?

For foaming agents, the most common thing we use is when we send express delivery, especially some fragile items. At this time, because the box is relatively large, the gaps are relatively large. In order to prevent the items being sent from being damaged by running back and forth inside, the courier will spray some foaming agent in the empty space of the box. After spraying in, the foaming agent dries quickly. At this time, the foaming agent plays both a fixing and buffering role. To put it simply, the foaming agent is actually foam board.

Does foaming agent on fenders soundproof?

1. I think foaming agent on fenders definitely plays a soundproofing role. Because I work in the tire industry, I understand that sometimes, the noise is not necessarily caused by the tires. Most of them are caused by the impact sound caused by the tires rolling up stones and the like and hitting the lining of the fenders when they are running. If a large amount of foaming agent is filled, it can make the fender lining fuller. For example, when we hit an empty bottle and a bottle filled with water, our most intuitive feeling is that the empty bottle is louder, and the sound of the bottle filled with water is relatively small and low, so supplementing the foaming agent is definitely useful.

2. I once dismantled the taillight of a Lufeng X7 car. The rear fender and bumper were filled with a large amount of foaming agent. There is no doubt that this is to increase the buffering force of the car in the event of a collision, and it must be for sound insulation.

Does foaming agent work when car tires make loud noise?

It is useful, but it is not very effective, and it will make it more difficult to disassemble the fenders and repair other parts later.

If the tires are noisy, you can check if it is a problem with the tire model. You did not say what kind of car you have or what type of tires you have. For example, if you drive a BBA car, most of them are run-flat tires. Of course, the noise is loud because the tires are hard and have thick sidewalls, so the noise is also loud. This can be solved by replacing the tires later.

The second thing is that if you don’t want to change tires, you can solve it by doing sound insulation. However, this sound insulation is professional, and it does not mean that you just fill the gaps with sound insulation materials. This kind of sound insulation is the most effective, but it is not cheap. If good materials are used, the price of complete vehicle sound insulation ranges from 5,000 to tens of thousands. The price varies greatly depending on the car model and materials.

By the way, this kind of additional sound insulation will increase the weight of the car. Better materials will weigh almost 200 kilograms, which is equivalent to the mass of an adult, so fuel consumption will increase.
