Paint Protective Film
What is Invisible Car Clothes?
The invisible coat is a lacquered protective film, which is Paint Protective Film, which stands for PPF,Some people call elephant skin, take thick wear - resistant meaning.It is called lacquer protective film.But in fact the most The first invisible car suit is not called invisible car suit, but called "Elephant skin" Not on the car, but on the let Somewhere you didn't expect. You want to know?
Development of invisible car clothes
Elephant skin was first used on U.S. military helicopters to protect the edges of their propellers as far back as the 1960s.
By the 1970s, elephant skin was being used to protect the radome paint of the U.S. military's stealth fighter.
In the 1990s, automotive elephant skins became commercially available, and auto racing events such as rally racing and Formula racing use automotive rhinoceros skins to protect the sponsor's icon and keep it intact in the event of a crash.
Today, in the 21st century, it is completely applied to the car, for paint protection.
Composition structure
Auto paint protective film, also called invisible car coat, is used to protect the auto paint surface from damage of thermoplastic polymer material transparent film.
Three elements
substrate
The substrate plays a 70% role in the coating.Therefore, the raw material supply of substrate, film extrusion technology, and the monopoly of automobile film production technology, determines the status quo of price and quality polarization of the invisible car market.
glue
High-quality glue will not leave scars on the car, of course, this has a lot to do with the construction of technical problems.
coating
The coating is in direct contact with the outside world, so it is necessary to directly face acid rain, guano, dust, etc., can resist the influence of these foreign objects is largely which determines the service life of the invisible clothing.The coating has a smooth surface, which has a better mirror effect than car paint, and makes the car look shinier when applied.
Substrate evolution
Advantages:
Hard material, good impact resistance, low price
Advantages
Increased toughness
Advantages
With excellent wear resistance, ozone resistance, high strength, good elasticity.
With good low temperature resistance, oil resistance, chemical resistance and other properties.
Recyclable processing and utilization, environmental protection.
Disadvantages
can not achieve the edge, drop glue.
Can not resist scratches, short service life within a year, yellow orange peel, cracking, hair black phenomenon.
Can not be recycled twice, pollute the environment
Disadvantages
Poor weather resistance
Poor resistance to alkaline corrosion
It will turn yellow gradually
The scratch cannot be repaired
Disadvantages
The production process is complex, the yield is low, the manufacturing cost is high
disadvantage
● Low tensile rate
● The warranty has no TPU length
advantage
● It has the same physical property and quality as TPU
● Give consideration to the performance of the simultaneous price is higher
● Recyclable processing and utilization, environmental protection
Comparative advantage of substrate layer
| material | Protective effect | Yellowing resistance rating | Scratch repair function | Remove the glue residue | defect |
| PVC | none | Level 1 | none | have | Cracking and yellowing |
| PU | have | Level 3 | none | local | Yellowing, water spots, not corroded |
| TPH | have | Grade 5 or above | have | local | Weak protection ability |
| TPU | have | Grade 5 or above | have | none | none |

TPU classification
TPU aromatic clarity is not high, light stability is not strong, easy to yellow.
The arrangement density of TPU aliphatic is high, which is several times that of aromatic. The coating and adhesive layer can be firmly absorbed after being applied, with up to 30,000 contacts, which are not easy to fall off and separate, not easy to foam and warp, and the protection performance is more durable. Not only can it keep its own color unchanged for a long time, but it also has good anti-yellowing and anti-aging properties!
How to identify the material?
1
color
1. PVC is translucent and slightly yellow
2. TPU is transparent and translucent, the higher the quality of TPU, the higher the transparency
3. TPH fluorescent blue
2
Elasticity
1. PVC is inelastic, and the belt rebounds slowly after being folded.
2. TPH has a certain resilience
3. The TPU strap has the same resilience as a rubber band, and its stretchability is very good
3
the smell
1. The smell of PVC is pungent after burning
2. After TPU burns, it contains the fragrance of ethanol
4
combustion residue
1. After burning, PVC is carbonized and hard, and it turns into powder after hand-twisting
2. TPU is a black viscous liquid after burning, and it will be sticky when touched by hand, and it will be drawn.
5
toughness
1. PVC has no toughness at all
2. TPH is whitened after stretching
3. High tensile rate of TPU
6
the coating
1. After TPH is strongly stretched, the coating can be peeled off with fingernails
The coating
level one
The first layer is a 0.5mil polyurethane clear film layer, an elastic polymer used to eliminate dust adhesion, contamination and surface scratches: the main function is an antifouling coating
Second floor
The second layer is a special 0.6mil polyurethane film, which is very tough and can be elastically restored by any stretching: combined with the first layer, the main function is to repair
the third floor
The third layer is a 1.6mil specially developed acrylic copolymer, which has strong adhesion to the paint surface and strong removability: the main function is to remove without residue
Adhesive function
PROTEGT THE ORIGINAL PAlNT
LET THE PAINT NEVER SCRATGH
RESIST ALL EXTERNAL POLLUTION
AGING AND RUSTING OF PAINT SURFACE
PREVENT ACCIDENTAL SCRATCHING
SUPER RESISTANT TO HAZARDS
Paint protective film function
importance
Why protect original car paint?
1. The process is complicated, and the uniformity, thickness and color of the post-spray paint can never be restored to the original paint effect
2. Car paint is an important part of determining the value of a vehicle
