Advantages of PVC
- Aug 02, 2017 -

A beautiful appearance
In this sense, PVC film market prospects are very promising. With the development of the Times, PVC is also with its good performance, simple process and many other advantages gradually won people's favor, has been more and more people accept and recognition, in Europe and the United States PVC is the construction industry pet, PVC in People's daily life everywhere. PVC can not only show the color of nature, but also the color of people's imagination. In Germany, 40% of the furniture is made of PVC surface materials, see those colors natural, gorgeous color, rich and diverse, beautiful design, elegant style and high-end desk, bookshelf, sofa, kitchen cabinets, who will not be the streets of those devastated "white trash" Lenovo together, but also do not think of it is PVC blister film to give them such a beautiful coat.

II. Perfect structure
PVC is mainly composed of polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility and so on. It is a kind of synthetic material that is popular in today's world and has been widely used. Its global use is ranked second in all kinds of synthetic materials. According to statistics, only 1995 years one years, PVC production in Europe is about 5 million tons, and its consumption is 5.3 million tons. In Germany, the average production and consumption of PVC is 1.4 million tonnes. PVC is being produced and applied worldwide with a growth rate of 4%. In recent years, the growth of PVC in Southeast Asia has been particularly significant, thanks to the urgent need for infrastructure construction in Southeast Asia. In the material that can produce three-dimensional surface film, PVC is the most suitable material.
PVC can be divided into soft PVC and hard PVC. Soft PVC is commonly used in flooring, ceilings and leather surface, but because soft PVC contains softener (which is also the difference between soft PVC and hard PVC), easy to brittle, not easy to save, so its scope of use has been limited. Hard PVC does not contain softener, so flexibility is good, easy to shape, not easy to crisp, non-toxic non-polluting, long save time, so has a great development and application value. Hereinafter referred to as PVC. The essence of PVC is a vacuum blister film, used for all kinds of panel surface packaging, so also known as decorative film, adhesive film, used in building materials, packaging, medicine and many other industries. Building materials industry accounted for the largest proportion, 60%, followed by the packaging industry, there are a number of other small-scale applications of the industry.

III. Strict process
PVC can be widely used in building materials industry, there are two important reasons: First, PVC unique performance (rain, fire, anti-static, easy to shape), the second is the low input of PVC high yield characteristics. PVC film has high resistance to light and fire resistance, to ensure high-quality PVC film. So overall, PVC is actually a low input, high yield products.
Melting Temperature: 185~205c Mould Temperature: 20~50c
Injection pressure: Can be large to 1500bar pressure: can be large to 1000bar injection speed: In order to avoid material degradation, generally with a considerable injection speed.
Runner and gate: All conventional gate gates are available. If the smaller parts are machined, it is advisable to use a needle-shaped gate or a submerged gate, preferably a fan-shaped gate for thicker parts. The minimum diameter of the needle-shaped gate or submerged gate should be 1mm, and the thickness of the fan gate should not be less than 1mm.
IV. Extraordinary performance

What is the difference between PVC film and ordinary adhesive film? Ordinary adhesive film is at room temperature directly with glue affixed to the surface of the plate, so after a year or two, the film will be easy to fall off. PVC film is the application of a dedicated vacuum press in the 110 degree of high-temperature pressure attached to the surface of the plate, it is not easy to fall off.
PVC is completely non-toxic and tasteless to human skin or respiratory system without any stimulation, for those who are allergic to wood and paint, the use of PVC membrane packaging furniture or kitchenware is very suitable. By using PVC membrane as decorative film, people can avoid the use of MDF, particleboard, plywood and fibreboard, reduce the use of wood, thereby reducing the damage to forests and the environment.
The use of PVC has caused great controversy in Western countries, and many people have tried to replace PVC with various other materials. But the quality of PVC has proved to be no less than other substitutes, while the cost is cheaper than these materials.
V. Bright FUTURE

At present, PVC industry has developed rapidly in the world, the prospect is broad, all countries are optimistic about the potential of PVC and its benefits to the ecological environment, PVC is with its superior, unique performance to the world to prove its role and status is currently no other products can be replaced, social development needs it, environmental protection needs it, it is our human society civilization progress inevitable trend.
