TPU Clear Car Paint Protection Film is a specific type of automotive protective film, also known as car wrapping or transparent car protection film. It is typically made from a material called Thermoplastic Polyurethane (TPU). This thin film is transparent, hence the term "clear," as it has minimal impact on the appearance of a car when applied to its surface.

The primary purpose of TPU Clear Car Paint Protection Film is to safeguard the car's paint surface from scratches, stone chips, UV radiation, and other environmental damages. It helps preserve the car's appearance, preventing paint peeling or discoloration, thus extending the overall visual lifespan of the vehicle.

They not only enhance the appearance of living spaces but also improve the living and working environment. Decorative films are versatile and easy to apply, suitable for flat, curved, and spherical surfaces. They are cost-effective and make it exceptionally easy to cover defects or modify styles.

Sun control film is made of PET (polyethylene terephthalate) as the base material and is produced using advanced multi-layer metal sputtering technology, vacuum technology, ion technology, and thin-film physics, as well as fine chemical engineering techniques. This makes it highly efficient in heat insulation, with high tension, high elongation, and strong resistance to acids and alkalis. Additionally, it offers a rich and natural color. Test results indicate that it can block 81% of solar energy. When outdoor temperatures reach 38-39 degrees Celsius, it can reduce the temperature by 3-5 degrees compared to regular glass, resulting in over 30% energy savings in air conditioning costs. It is a high-tech and energy-efficient safety material.

1. UV Protection: Applying sun control film can block 99% of ultraviolet (UV) rays, significantly reducing furniture fading caused by UV rays and extending the lifespan of furniture and other items.

2. Safety and Explosion Resistance: Sun control film has explosion-resistant properties, preventing injuries caused by the natural breakage of regular glass and tempered glass, thus ensuring personal safety.

3. High Heat Insulation: With a heat insulation rate of up to 79%, one layer of film is equivalent to a 24 cm thick brick wall. It effectively blocks the heat radiation and conduction of solar energy, leading to savings in air conditioning expenses. It improves the efficiency of HVAC systems without the need for expensive cooling capacity.

4. Glare Reduction: It makes the indoor environment more comfortable and helps maintain comfortable conditions for the eyes by reducing glare when looking from indoors to outdoors.

1) Comparison with Regular Glass:

Some public buildings have window-to-wall ratios exceeding 20%, with energy consumption through windows accounting for approximately 50% of the building's total energy use. About 75% of energy losses through windows are attributed to glass, especially for windows with a shading coefficient (SC) of around 0.8 or higher. This leads to what is commonly referred to as the "greenhouse effect" due to the excessive introduction of solar energy. Energy-efficient renovation in public buildings, particularly window and façade upgrades, is crucial for energy conservation. Glass retrofitting for existing buildings offers two main options: replacing existing glass with energy-efficient glass or applying architectural insulating safety film. The latter is a faster, more convenient, and effective solution.

2) Comparison with Laminated Glass:

Laminated glass is typically used in banks and offers protection against break-ins and bullets. However, it has relatively poor thermal insulation properties and does not effectively block ultraviolet (UV) rays. Laminated glass has complex production processes and high technical requirements. Moreover, the cost of the PVB material used for interlayer lamination is significantly higher than the cost of the glass itself. Architectural film for glass is easier to install, more cost-effective, and offers good performance in terms of thermal insulation, light transmission, and UV protection. After applying the film, the strength of the glass can be increased by 4 to 40 times or even achieve bullet-resistant effects, comparable to laminated glass.

There are many dangers associated with inferior architectural glass films. Some consumers may believe that there is no significant difference between cheap films and expensive ones. However, this is not the case.

Authentic glass films undergo professional testing, ensuring that the chemical components they contain pose no harm to the human body. They have passed relevant test reports. Consumers can request to see these test reports and other related procedures when making a purchase. Genuine glass films are exclusively produced abroad, accompanied by authentic and valid customs declarations and certificates of origin. These can be verified on the official website of the respective manufacturer. Inferior glass films not only result in wasted money but also pose health risks. In fact, inferior thermal insulation films exhibit several disadvantages, primarily in the following aspects:

(1) Shoddy and inferior high-transparency thermal insulation films offer poor thermal insulation performance. Customers can request on-site testing with relevant instruments to verify this.

(2) Inferior films have low clarity and lack an anti-scratch layer, making them less wear-resistant and unable to guarantee safety.

(3) Adhesives in inferior films may contain residual volatile formaldehyde, benzene, xylene, and other harmful substances, emitting a strong and pungent odor, thus seriously endangering human health. Relevant test reports can be requested to confirm this.

(4) UV blocking may not meet the standard in inferior films, and their colors can be dazzling, prone to fading, which is detrimental to appearance.

(5) The thermal insulation performance of inferior films is quite unstable, with the thermal insulation rate decreasing over time.

1. Coated glass: Coated glass is to coat one or more layers of metal, alloy or metal compound on the surface of the glass to change the properties of the glass. According to different characteristics, it can be divided into heat reflective glass and low-emissivity glass.

Heat reflective (sunlight control) glass is generally coated with one or more thin films composed of metals such as chromium, titanium or stainless steel or their compounds on the surface of the glass to make the product rich in color and have appropriate transmittance for visible light. It has high reflectivity for infrared rays and low transmittance for ultraviolet rays. Therefore, it is also called solar control glass. Compared with ordinary glass, the shading coefficient is reduced, that is, the shading performance is improved, but the heat transfer coefficient is not changed much.

Low-emissivity (LOW-E) glass is a thin film composed of multiple layers of silver, copper or tin and other metals or other compounds coated on the glass surface. The product has high transmittance of visible light and high reflectivity of infrared rays. Good thermal insulation performance, due to the poor strength of the film layer, it is generally made into insulating glass and not used alone.

2. Insulating glass: Insulating glass is made of two or more pieces of glass framed by an aluminum hollow frame and sealed by cementing or welding. A free space is formed in the middle, which can be filled with dry air or inert gas. Its heat transfer coefficient U is The single-layer glass is small and has good thermal insulation performance, but its shading coefficient SC decreases very little and the heat reflectivity of solar radiation does not improve much.

The key to improving the explosion-proof performance of glass is to mitigate external impact forces, primarily achieved through several aspects:

1. Utilizing the adhesive layer and metal coating to enhance the rigidity of the glass, which helps to distribute the impact force across the surface. Metals are known for their good ductility and toughness, so the metal coating can effectively offset and disperse the impact. Even if the glass shatters, the metal material within the glass film generates a tensile force and, together with the adhesive layer, holds the glass fragments in place, preventing them from splintering and effectively ensuring personal and property safety.

2. By allowing the unique particles within the film's interlayer to slide against each other, it dissipates the impact energy transmitted through the glass to the safety film, providing a buffer against most impacts and creating unique impact resistance. Furthermore, the longer the film is adhered, the stronger the bond between the film and the glass becomes. It has been estimated that this can enhance the glass's strength by 2-7 times, effectively preventing glass from shattering and causing injuries due to external impacts.

3. The primary material composing the film, polyester-based film, is known for its heat resistance, durability, high toughness, moisture resistance, and resistance to extreme temperatures. It can significantly absorb external impact forces, achieving a safety effect.

The development history of glass window film is inseparable from the development history of its raw materials and process equipment, especially the development history of vacuum evaporation coating technology.

The United States began to develop polyethylene-based glass window film (tea paper) in the 1960s. At that time, most buildings used ordinary float glass, and the energy consumption caused by door and window glass accounted for more than 1/3 of the entire building. When people transferred membrane materials used in aerospace to building doors and windows, they found that it could significantly improve the thermal insulation and energy-saving properties of buildings. Therefore, major companies began to conduct research on glass window films. 3M Company issued the first patent for solar insulation film in 1966. The worldwide energy crisis in 1970 prompted people to accelerate the development of glass films. The vacuum evaporation coating process was applied to PET base films, which made great progress in glass window film technology.

In 1977, Deposition Technology, Inc. (Deposition Technology, Inc. of the United States) (the company was acquired by the Belgian Bekaert Group in 1991 to form Bekaert Special Coating Company) applied advanced magnetron sputtering production to the U.S. Air Force and NASA. Technology was introduced into the glass window film industry, and in the early 1980s it became the first manufacturer in the world to use the magnetron sputtering process to produce glass window films.
