PVC letters refer to the word for advertising decoration made of PVC, which is an advertising decoration material. The full name is Polyvinylchloride, the main component is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the lowermost layer is back-coated adhesive.
It is a synthetic material that is widely used in the world today. Among various synthetic materials, global use of PVC ranks second. According to statistics, in 1995 alone, PVC production in Europe was close to 5 million tons, and its consumption was 5.3 million tons. The production and consumption of PVC are an average of 1.4 million tons in Germany and PVC is being produced, that applied worldwide at a rate of 4%.
In recent years, the growth rate of PVC in Southeast Asia has been particularly significant, owns to the urgent need for infrastructure construction in Southeast Asian countries. Compared with the materials that can produce three-dimensional surface films, PVC is the most suitable choice of material.
Soft PVC is generally used for the surface of floors, ceilings, and leather, but because soft PVC contains softener, this is also the main difference between soft PVC and hard PVC, it is easy to become brittle and difficult to store, so its scope of use has been limited. On the contrary, hard PVC doesn’t contain softener, therefore it has good flexibility, easy to form, is not brittle, non-toxic and non-polluting, and has a long storage time, so it has great development and application value.
The essence of PVC is a vacuum plastic film, which is used for surface packaging of various types of panels. Therefore, it is also called decorative film and adhesive film, used in many industries such as building, packaging, medicine and so on. The building materials industry accounts for the largest proportion of 60%, followed by the packaging industry, there are several other small-scale applications. pvc letters exterior is a polyvinyl chloride plastic with bright color, corrosion resistance, and durability. Due to the addition of some toxic auxiliary materials such as plasticizer and anti-aging agents in the manufacturing process, its products generally do not store food and medicine.
In Europe and America, PVC is the darling of the construction industry, and PVC is everywhere in people’s daily lives. PVC can not only show the color of nature but also indicate the color of people’s fantasy. In Germany, PVC is used to be a surface material of 40% of the furniture. Seeing those desks, bookshelves, sofas and kitchen cabinets that are natural in color, gorgeous in color, rich in variety, beautiful in design, elegant in style and high in style, no one will associate them with the ruined “white rubbish” on the street, not to mention that PVC blister films give them such beautiful coats.
There are two advantages of PVC letters:
The unique performance of PVC (rainproof, fireproof, anti-static, easy to form)
Low input and high output
Why can PVC have the above two advantages? Let’s find the answer from its production process.
How to make letters using pvc?the production process of PVC is not complicated. The ordinary production line generally consists of a rolling machine, a printing machine, a back coating machine, and a cutting machine. The thickness is only produced by the direct motion stirring of the rolling machine, the roller rotation, and the high temperature rolling. A film of 0.3 mm to 0.7 mm is produced at the same time and printed on the front side of the film by a printing machine, and a back coat is attached to the backside of the film by a back coater. Don’t underestimate this layer of back coating, it is an important guarantee of the quality performance of PVC film.
The back coating consists of special material and is a high-energy affinity agent. It is because of this back coating that the PVC film can be tightly blended with the medium-density board or other sheets, and the glue is not opened for ten or even fifteen years. The biggest problem with ordinary veneers is that it can’t solve the problem of film shedding. Since the entire production process is carried out at high temperatures (220 degrees inside the rolling machine), this makes the PVC film highly resistant to light and fire, ensuring high-quality PVC film.
Although painted pvc letters has excellent quality assurance, some people may say that PVC is a chemical product after all and it is not comparable to natural materials. It can not eliminate toxicity and odor, and it is inevitable to harm the environment. This is not the case. It is because the raw materials for the production of PVC film.
