What are the benefits of car heat insulation films? Which brand is good? How to choose

The heat insulation film can effectively block the ultraviolet rays in the sun, so that the instruments and interior of the car will not deteriorate so quickly; In addition, it can also play a role in riot prevention. The most famous brand is, of course, 3M, there are many counterfeit 3M on the market, you must first check the local regular 3M construction authorized store on the Internet before going to the film. Generally, if you choose the film, you can choose 40% of the front file, and 50%-60% of the other generals.

Automobile explosion-proof heat insulation film is a necessary product for car window glass to improve heat insulation and safety, people have been actively or passively exposed to and understand the car explosion-proof heat insulation film when buying a car, but the knowledge we have obtained about identifying the heat insulation film is quite poor, not as clear and clear as a car. Since the performance and quality of automobile heat insulation film have not been clearly stated, this gives those unscrupulous businesses an opportunity to damage consumers with shoddy quality from time to time.

For the production technology of automotive heat insulation film, from the initial dyeing (coloring) process, vacuum electroplating aluminum film, vacuum electroplating aluminum layer and dyeing mixed film, magnetron sputtering metal film to magnetron sputtering multi-layer metal film, with the continuous progress of technology, the performance of the product is also continuously improved, and its production cost and selling price are very different. However, at present, there is no brand in the market that can clearly indicate which type of production technology it belongs to, but uses confusing concepts and using some scientific and technological terms to introduce its products. Here, relevant experts remind consumers to pay attention to some matters when purchasing automotive heat insulation film:

Be sure to choose a big brand.

I use Ray-Ban's.

Although it feels a bit pricey.

But it's definitely worth it.

Because of the summer. I was very hot before the dark.

Like a large steamer, too.

Right now. The temperature should be lowered by several degrees.

Film. Mainly low-grade ultraviolet radiation.

One is that the driver will be much more comfortable after driving.

If you post a front-file.

And then the front doesn't feel too hot.

There are many good films, but if it is cost-effective, it should be the Northern Lights solar film. It has stable quality assurance, a nationwide sales network, perfect after-sales service and an eight-year quality warranty. After 14 years of ups and downs, it has become a leader in the industry.

I am also a big fan of the Northern Lights, and I have been buying a car for 4 years since I was 27 years old. There are also many friends around me who use this brand, and everyone thinks it's very good. Recommend this brand for your reference.

The top ten rankings of automotive films are: Meiji, Dragon Film, 3M, Weigu, Federal, American Bef, Bekaert, Johnson & Johnson, Ray-Ban, Amber Optics, etc.

2. Llumar dragon membrane.

Affiliated to Eastman Chemical, it has significant anti-scratch function, the world's most respected high-performance window film brand, the world's largest window film manufacturing enterprise Dragon Film, and is produced by the world's largest window film manufacturer CPFILMS. CPFILMS is known for its advanced technology development, superior manufacturing capabilities, extensive global distribution, and customer service levels.

3. V-KOOL.

Eastman Chemical's famous brand, developed the first intelligent window film that can screen the spectrum, its thermal insulation effect is well-known all over the world, favored by top European car manufacturers, V-KOOL (Weigu) heat insulation film manufacturer is located in Silicon Valley, the United States Shaohua Technology, as a NASDAQ-listed company Shaohua Technology has long been engaged in the development of spectrally selective films required for military and space technology.

Structure & Performance.

The most basic composition of the film is a polyester substrate (PET) with a scratch resistance layer (HC) on one side and a adhesive layer and protective film on the other.

PET is a material with strong durability, strong and moisture resistance, high and low temperature resistance. It is clear and transparent, and has been treated by various processes such as metallization coating, magnetron sputtering, and sandwich synthesis to become films with different characteristics.

Specialized manufacturers of membranes often use their respective proprietary adhesives for sandwich synthesis and adhesive lining. It is mainly divided into: pressure-sensitive adhesive and water molecule activation adhesive.

The main varieties of heat insulation film are: transparent thermal mirror, heat reflection heat insulation film, low reflection heat insulation, low emissivity (low-e) film, etc.

Considering the safety and ease of construction, the thickness of the substrate of the heat insulation film should be more than 2mil.

Many friends are in **, which car heat insulation film is good, so let's talk about it. There are two types of automotive heat insulation films, ceramic films and heat absorbing films.

The basic principle of ceramic membrane is to use the reflection of metal material to carry out heat insulation, and according to the alloy layer in the film, the infrared induction with heat energy in natural light can be selectively reflected, so as to achieve the effect of long-term heat insulation.

The heat absorbent film contains a large amount of heat absorber in the film layer, and its basic principle is to use the heat absorber to digest and absorb the heat of natural light to achieve the effect of heat insulation.

Compared with the two, the thermal insulation effect of ceramic film will be better, and it is not easy to cause shortcomings such as secondary radiation sources of heat generation, and the thermal insulation time is also longer; And the heat absorption effect of heat absorption film is limited, so its heat insulation effect is general.

Which well-known brand of car heat insulation film is better.

Here are some examples of some well-known brands of automotive heat insulation films.

1.Master Wrap.

V-KOOL is the world's only "convenient" glass film that can be selected for spectrometers, with high thermal insulation and light transmittance, with 73% visible light transmittance and 94% insulated infrared induction heat convection. To put it simply, it can have a cooler extracellular fluid, and has the functions of faster deheating, ultraviolet light maintenance, and anti-crushing.

2.Dragon film.

Dragon Film has a professional window film production and processing industry base, with a variety of product models to meet the different requirements of customers.

The functions of this brand of automotive heat insulation film are: reducing dazzling glare and improving the comfort of drivers; Isolate 99% of harmful ultraviolet light; Reduce the load of air conditioning and improve the high efficiency of gasoline and diesel; Do not weaken the vision of safe driving at night; In the event of a safety accident, it is conducive to fixing the fragments of damaged laminated glass; Explosion-proof anti-theft features in the true sense of the word.
