Noise-absorbing cotton is known to some car owners. As its name implies, sound-absorbing cotton has the effect of sound insulation and heat insulation. Car noise insulation cotton really has the effect of noise insulation? Today Xiao Bian will take you to understand, what is the car noise insulation cotton ? The real role of noise insulation cotton is actually this, do you really know?

What is car noise insulation cotton

Many friends have just bought a new car and they will add some accessories to the car or dress it up, such as a guard under the engine or car noise insulation. In general, the original factory has been equipped with soundproof cotton for the car. The material of the soundproofing cotton will be relatively thick and will be fixed in the car's car cover, which looks unconventional and beautiful. If there are two types of sound insulation cotton in the latter stage, one is a special plastic flocking material for the special car; the other is a free-cut aluminum foil sound insulation cotton. Special car-specific materials are basically buckled and fixed. There will be a good set of buckles on the car cover. It is more suitable than the free cut material.

The real effect of soundproofing cotton is actually this

1, sound insulation cotton has a very good insulation effect of temperature. Therefore, with the sound insulation cotton, the surface of the engine cover can be well protected from rapid aging. Some car owners know that after a long time driving, the temperature inside the engine compartment will be very high, and the cover table paint will quickly age and crack after long-term high-temperature baking. Therefore, we usually find the hood of some cars. Aging loses its luster, while other places are relatively new.

2. When the temperature in the winter is relatively low, the insulation wool can also be well protected. The temperature in the cabin will not drop rapidly, so the temperature in the cabin will not drop abruptly, which can greatly reduce the damage caused by restarting the engine. . In other words, when the engine is kept at normal temperature, frequent start-stop damage is not significant, and if the temperature is too low, frequent start-stop damage is significant. Therefore, the protection of soundproofing cotton will be much less effective.

3, many people will feel that after the installation of sound insulation cotton, will not protect the temperature inside the cabin so as not to distribute the temperature will be dangerous? In fact, this is completely no need to worry, qualified soundproof cotton also has a certain degree of flame retardant Sex. Second, the engine cooling is mainly achieved through the cooling system. Therefore, the insulation wool is only isolated from the temperature and does not increase the temperature.

Xiao Bian concludes: On the above, what is the real effect of car noise insulation cotton ? Sound insulation cotton is actually this related content, Xiao Bian introduced to this, understand the above, you are not surprised to see it? Car noise cotton unexpectedly There are also these functions that I hope can help your car use.

Manufacturer Supply 0.3mm Clear Rigid Thermoplastic PET Roll Film For Vacuum Forming

PET hard film has good toughness, high transparency, easy to burn, and does not produce harmful gas when burned. It is an environmentally friendly material, but the price is high, and it is suitable for high-end blister products. The blister blister in European and American countries generally requires PET hard film, but It is not easy to heat seal, which brings great difficulties to packaging. In order to solve this problem, people laminate a layer of PVC Film on the surface of PET, named PETG rigid sheet, but the price is higher.

Introduction of pet sheet and its products
PET sheet is a new type of material developed in recent years. With its excellent toughness, high strength, high transparency, recyclability, and excellent environmental performance of burning and not producing harmful gases, it has gradually been greatly appreciated by consumers and producers. Green ignorance; follow the trend of environmental protection.
main feature: 
1. It has excellent transparency and smoothness and good display effect.
2. Excellent surface decoration performance, can be printed without surface treatment, easy to suppress patterns, easy to metal processing (vacuum metal coating)
3. Has good mechanical strength.
4. Good barrier performance to oxygen and water vapor.
5. Good chemical resistance, can withstand the erosion of a variety of chemical substances.
6. It is non-toxic and has reliable hygienic performance. It can be used for packaging food, medicine and medical equipment, and can be Y-ray sterilized for the packaged items.
7. It has good adaptability to environmental protection and can be recycled economically and conveniently; when its waste is incinerated, no harmful substances harmful to the environment are produced. The thermoforming performance is good, which is comparable to ordinary pvc sheets, and can be vacuum formed to produce PET thermoformed products with excellent performance; PET sheets are considered to be an ideal packaging material that meets the requirements of environmental protection.
Performance parameters:
1. Density 1.36g/cm Oxygen transmission rate 4-4.5cm*mm/(m*24h*0.1mpa)
2. Tensile strength longitudinal 53MPA moisture permeability ≈ 3G*mm/(M*24H)
Horizontal 53MPA, the highest operating temperature is nearly 70 degrees
3. Elongation at break 250% longitudinal direction 250% transverse direction
4. Heated size change, longitudinal ≤5%, transverse ≤5%
5. Transparency≤3%
6. Hygienic performance meets the requirements of GB13113-91
The main purpose: 
Electronics, food, toys, color box windows, collar supports
