PU product application field

Furniture industry

In the furniture industry, imitation wood material is one of the main application directions of polyurethane rigid foam. The imitation wood material is light in weight and has the same density and strength as wood. The use of this material to make furniture will not only cause cracks after molding, but also reduce the production and manufacturing links. the cost of. With the increasing awareness of national environmental protection, wood-like materials will be more used in the furniture industry, thereby replacing the position of natural wood in furniture. 

my country is a big country in furniture production and processing in the world. Considering the total consumption of polyurethane in the furniture industry during the “Twelfth Five-Year Plan” period; during the “Thirteenth Five-Year Plan” period, my country’s real estate policy continues to be tightened, and the construction of affordable housing and low-rent housing will continue to accelerate. my country’s furniture industry will not be affected, and the public’s demand for polyurethane will increase at a rate of 5% per year.

When polyurethane rigid foam is used in the field of building insulation, it is the first choice material for its simple structure, long product life, high construction efficiency, high fire resistance grade and low comprehensive cost. [3] With the continuous implementation of my country's energy conservation and environmental protection policies, the construction industry will face more stringent tests during the "13th Five-Year Plan" period, and rigid polyurethane foam will be widely used in the field of building insulation. In addition, as an important waterproof coating, polyurethane is widely used in building roofs, exterior walls, ceilings, basements, kitchens and bathrooms, roads and bridges, etc. With the continuous development of my country's rail transit and high-speed railways, polyurethane waterproof coatings will also be widely used In the field of railway construction. [3] At present (2015), the polyurethane consumption in my country's construction industry is about 1.25 million tons, accounting for 20% of the total consumption, while the total consumption in the same industry in developed countries is 35%. Combined with data analysis, it is not difficult to find that my country's polyurethane rigid foam still has a lot of room for development in the construction industry. 

Shoemaking and tanning industry

China is the world's largest exporter and production base of footwear products. Footwear production accounts for 60% of the global total. Polyurethane (PU) material is a type of polyurethane. In addition, the slurry is mainly used to manufacture artificial leather and synthetic leather. Related Products. At present (2015), the polyurethane slurry used in shoe soles is less than 10%, which is still unable to match the average level of developed countries. 

However, with the continuous improvement of my country's industrial production technology, the manufacturing cost of polyurethane slurry will continue to decrease, and its development potential is beyond doubt. 

Transportation industry

There is no lack of polyurethane in the transportation industry, which mainly includes soft, rigid, and semi-rigid foams, as well as polyurethane elastomers, polyurethane glues, polyurethane sealants and polyurethane coatings. The total amount of polyurethane required for a molded car is about 30kg. The use of high-quality polyurethane products in the car is also one of the important factors to measure the car's grade. my country is a big automobile country, and it ranks first in the world in terms of the number of automobile manufacturing and the number of automobile ownership. According to relevant statistics, the annual consumption of polyurethane used in the automobile industry in my country is nearly 400,000 tons. With the continuous introduction of new energy vehicles, the consumption of polyurethane will have a broader room for growth in the automotive industry. 

In addition to the automobile industry, my country's cold chain transportation industry is also another area of ​​polyurethane development. With the continuous improvement of people's living standards in our country, more and more people's demand for flowers and aquatic products in various places has soared, which has driven the development of my country's cold chain transportation industry. Transport vehicles in the cold chain transportation industry usually use polyurethane rigid foam sandwich panels as heat insulation materials. At the same time, a large amount of polyurethane heat insulation materials are also needed during the construction of cold storage, which is also a major benefit for my country's polyurethane industry. [3]

Appliance industry

Refrigerators and freezers mainly use polyurethane rigid foam as the insulation material for home appliances. This material can effectively increase the internal volume of refrigerators and freezers under the same volume conditions, reduce the total amount of external shell materials, and not only reduce production costs, but also It can also reduce the weight of the refrigerator and improve the thermal insulation performance. In our country, the manufacture of a standard-volume refrigerator requires polyurethane rigid foam weighing about 6-8 kg, while a freezer requires about 11 kg of rigid foam. China is a large refrigerator manufacturing country and has gradually become the world's integrated base for refrigerator R&D, production, and transportation; the total amount of polyurethane rigid foam used in the refrigerator manufacturing industry in my country is about 800,000 tons per year. With the continuous implementation of the “energy-saving and emission-reduction” policy for home appliances in my country, the total amount of polyurethane used in refrigerators will show a downward trend, and various manufacturing companies will move toward a “green and environmentally friendly” development route. [3]

In addition, the thermal insulation materials of solar water heaters also use polyurethane rigid foam. my country's solar energy industry is an emerging industry. With the continuous optimization of energy structure, the solar energy industry will be further developed, and polyurethane industrial products will also be more favored. 

Sports industry

Polyurethane paving materials are widely used in the construction of sports venues, plastic runways in public stadiums, indoor basketball courts, and volleyball courts. In the past few years, the "poisonous runway" incident continued to ferment, causing the entire industry to be in a state of low-end and severe competition, and many small businesses operating without a license are making great profits. With the continuous improvement of the quality of my country's polyurethane industrial products, the quality of polyurethane paving materials has been improved. With a substantial improvement, the company continues to move towards environmentally friendly paving products.

Polyurethane can also be used in the packaging of fragile commodities, especially in the transportation and packaging of some precision instruments, handicrafts, and fragile products; this kind of products can also be used in aviation, aerospace, automobile manufacturing, liquefied natural gas transport vehicle (ship) manufacturing, etc. field.
