Description

I. What is car paint protection film?

Paint protection film (PPF, also called clear bra, clear film or clear paint film) is a thermoplastic urethane often self-healing film applied to painted surfaces of a new or used car in order to protect the paint from stone chips, bug splatters, and minor abrasions. This film is also used on airplanes, RVs, cell phones, electronics, screens, motorcycles and many other areas. Paint protection film is OEM approved by virtually all car manufacturers.
 
Paint protection film is installed on a limited basis by manufacturers on various pieces of cars at the factory (e.g. the rear arches of Porsches). This film is most commonly applied to high impact areas of vehicles which include: the hood, the front fenders, the front bumper, the side view mirrors, the rocker panels, the lower portion of the doors, and the rear guards behind the rear wheels. This is because these specific panels are the most susceptible to damage from rock chips and other forms of road debris from other vehicles, driving near construction, and even through self-inflicted damage—which is caused by simply driving due to the fact that debris is inevitably is kicked up from the tires rotating. The film is generally installed by certified trained professionals who receive supplies from outside distributors and dealers.
 
Paint protection film is made of thermoplastic polyurethane Elastomer, which refers to a class of polymer materials with properties that are similar to thermosetting rubber and the processing technology is similar to plastics. There are plastic segments (hard segments, HB) and elastic chain breaks (soft segments, SB) in the TPE molecular structure.). Because the hard segment and the soft segment are mechanically incompatible or incompletely compatible, TPE has both thermoplastic and elasticity. TP will show the elasticity of rubber at room temperature or low temperature, and it can be plasticized and formed at high temperature. TPE, it has an interactive cross-linked network structure. This kind of cross-linking is mainly based on physical cross-linking. It can be processed and formed without vulcanization. Moreover, the scrap and waste generated during the processing can be reused. Therefore, it is widely used in automobiles. Construction, wires, cables, electronic products, food packaging, medical equipment and other fields,
 
Polyurethane is just a new organic polymer material, known as the fifth largest plastic, thermoplastic polyurethane elastomer, tpu, is the first polyurethane material invented, and it is also one of the fastest-growing polyurethane varieties. The unique molecular structure of the thermoplastic polyurethane elastomer material with alternating soft and hard segments makes it not only maintain the high elasticity of rubber, but also have the high hardness and strength of plastics. Tpu has high strength, cold resistance, wear resistance, sound insulation, and solvent resistance. It is widely used in high-end manufacturing fields such as defense and military industry, electronic technology, petrochemical industry, resource exploration, medical and health, sports equipment, etc., which is the transformation of the above-mentioned industry.
 

II. Advantages of PPF


1. Paint Protection Film Retains a Car’s Resale Value
Paint protection film can increase and retain the resale value of your vehicle-the paint is better than those without PPF and the vehicles with paint protection films are usually better maintained and better taken care of.
 
2. Paint Protection Film Keeps Your Car Looking Brand New
Paint protection film can maintain the high-gloss appearance of your vehicle surface-for a glossy and polished appearance at all times and weather, giving your vehicle the ultimate treatment with a PPF application.
 
3. Paint Protection Film Repels Damage
From harmful UV damage to scratches and bug splatter, the environment is not kind to our cars. Paint protection film offers effective and durable resistance to elements that can cause discoloration, rust and paint damage.
 
4. Paint Protection Film Offers Invisible Protection
Without changing the original color, PPF can be an invisible protector.
 
5. Paint Protection Film is Cost Effective
Constantly repairing scratches, rust, and paint chips on your vehicle can get expensive. By preventing these damages from occurring in the first place, paint protection film will save you money on minor repairs. 
 
6. Paint Protection Film is Easy to Remove
A quality Paint protect film will not change its color and turn yellowish in years. If you want to replace the paint protection film, you can easily peel it off and it will leave no glue on paint surface.
 
7. Self-healing with minor scratches
The advance nano coating layer on the paint protection surface enables itself to heal with minor scratches and enhance the glossy looks.

III. Development of paint protection film

  1. Generation 1-PVC/polyvinyl chloride
abbreviation for. polyvinyl chloride; a synthetic thermoplastic material made by polymerizing vinyl chloride. The properties depend on the added plasticizer. The flexible forms are used in hosepipes, insulation, shoes, garments, etc.
PVC is definitely not the best material for car paint protection material, as it turns into yellowish color and it will crack in cold weathers, leaving glue on surface or almost impossible to peel off.
 
  1. Generation 2-TPH
TPH-Thermoplastic Polymer plasticized hybrid polyurethane
 
Advantage
It has the same physical properties and quality as TPU material at room temperature
Cost Effective
 
Disadvantage
Low stretch rate
Short lifespan
 
Coating: Adopt nano dense anti-leakage coating
①Using the water-repellent effect of the lotus leaf, it is difficult for oil stains and dirty water to adhere;
②The dense coating has super anti-permeability,
Thoroughly prevent rain spots, extinction, and oil infiltration;
③With scratch self-healing function.
 
Substrate:
Weather-resistant PVC film, and the PVC film uses excellent plasticizers to improve the PVC base material. It has good weather resistance and flexibility, and the QUV test of yellowing resistance can reach 1200 hours.
①Apply long-chain polymer plasticizer (hence the name TPH) to delay the precipitation of plasticizer;
②Balance weather resistance and flexibility, and strictly control the proportion of plasticizers added.
 
Adhesive layer: use removable weather-resistant glue
①The combination of large molecular weight, cohesive strength and long-term adhesion of gold can control the long-term stability of adhesion and cohesion;
②The glue is perfectly matched with the TPH film, can be repeatedly pasted, and rework stretch without leaving glue lines;
Remarks: PVC plasticizer has a significant impact on the adhesive layer,
Long-term storage will cause the initial adhesion to decrease. It is recommended to apply on the car within 6 months after leaving the factory.
 
  1. Generation 3-TPU
TPU-Thermoplastic urethanes
 
Advantage
excellent wear resistance
High strength and stretchability
low temperature resistance, oil resistance,
Chemical resistance
Recyclable for processing and utilization
environmentally friendly
 
Disadvantages
Complex production process
High manufacturing cost

Coating: adopting a new generation of hydrophilic anti-fouling self-healing and nano-dense anti-leakage combined double coating process
  • surface hydrophilic properties to wet the, the oil, dust and dirt attached to the surface can be taken away under the washing of water;
  • The dense coating has super anti-permeability, completely preventing rain spots, matting, and oil from penetrating;
  • With scratch self-healing function
 
Substrate: imported aliphatic TPU film
  • The yellowing resistance can reach the world's highest level 5 outdoor weather resistance;
  • Precise elastic modulus control to ensure the excellent construction performance of the product.
 
Adhesive layer: adopts removable glue imported from Ashland
  • The combination of large molecular weight, cohesive strength and long-lasting durability
To control the long-term stability of adhesion and cohesion to ensure no glue residue;
②The glue is perfectly matched with the TPU film, which can be repeatedly pasted, and the rework stretch does not leave glue lines on surface
 

 IV. Precautions after installation

Precautions After Install PPF
  1. Do not get in heavy rain at the same day of install.
  2. Do not drive over on highway in 5-7 days to prevent possible peeling off at edges.
  3. Do not use a high-pressure washing, especially for the corners and edges.
  4. Clean debris, dust, tree leaf’s, seeds, birds remain in time.
  5. water mist will disappear in about 5-7 days.
  6. Avoid excessive stretching during construction.
