HONYFLUO®PVDF, polyvinylidene fluoride, is a versatile fluoropolymer which is both strong and tough as reflected by its tensile properties and impact strengths. PVDF has excellent resistances to creep and fatigue. In thin sections, such as films, filament, and tubing, PVDF components are flexible and transparent. PVDF resin is produced by the Arkema and Soltex companies and sold under their respective tradenames of Kynar and Solef.
Where load bearing is important, PVDF fluoropolymers are rigid and resistant to creep under mechanical stress and load. Because PVDF is stable to sunlight, and other sources of ultraviolet radiation, it is widely used as base resins for long-lasting exterior coatings. An additional advantage over other fluoroplastics is that PVDF can be welded into tanks for acid and corrosive chemical processing in elevated temperature environments.
Special Properties of PVDF polyvinylidene fluoride
1. Its Anti degeneration is also one of the optimal fluoride resins.
9. PVDF has a good chemical stability. It will not be corrupted by acid, alkali, strong oxidizing agent and halogen at room temperature; it will not be affect by ordinary organic solvents; it can only be swelling or partly dissolved by a handful of chemicals such as fuming sulfuric acid, alkali, ketones and ether; it can be dissolved into a colloidal solution by strong polar organic solvents such as dimethyI acetamide and Dimethyl Sulfoxide (DMSO).

Recently, the author visited (or interviewed) the bus giants Yutong Bus, Suzhou Jinlong and Zhongtong Bus, and met Yutong Bus Chairman Tang Yuxiang, Suzhou Jinlong General Manager Wu Wenwen and Zhongtong Bus General Manager Sun Qingmin.
Although the three CEOs generally judge the bus market this year as a whole, they are different from the overall market judgment. The three CEOs are optimistic about this year's new energy bus market.
New technology route ushered in plug-in hybrid mature product
A new product wants to be recognized and purchased by more users. Then, the maturity and perfection of the product itself and the improvement of performance are very important. It can be said that the three bus companies believe that the 2014 new energy bus can sell well. An important reason is the product's maturity and performance.
Hager hybrid bus adopts ISG hybrid system
Wu Wenwen told reporters: “Haeger buses have a new start for new energy buses. It can be said that Hager buses have been making new energy buses for many years, but now they are all over.†Wu Wenwen said so, not referring to Hagrid’s previous efforts. The new energy bus is not doing well, but this year will be a new level. In fact, the performance of the Hager hybrid bus in 2013 was impressive, with sales of more than 940 vehicles, and its growth rate was ahead of the industry. Wu Wenwen said that Hager's new energy bus "starts from the beginning," and its important reason is that Hagrid's plug-in hybrid buses have new technical routes and more fixed parts suppliers, as well as more stable and mature products. .
When interviewed by Director of the New Energy Research Institute of Higer Passenger Cars, Weilin Zhang revealed: “Hager hybrid buses use the ISG hybrid system, which is a coaxial direct-drive hybrid system where the motor and the engine directly drive the wheels of the vehicle; The other domestic hybrid buses mainly use the BSG hybrid system, that is, the belt-driven generator. "The current research and development of ISG hybrid systems is very few in China, and Haige is one of them." Zhang Weilin further explained The advantage of this system lies in the fact that “vehicles using the ISG hybrid system do not require gearboxes for power transmission and torque conversion, which reduces the loss of power to the transmission system and results in higher transmission efficiency.â€
It is understood that, in addition to Hagrid's own ISG hybrid system, Yutong also uses the ISG system. Yutong can be said to come from behind in the field of new energy buses, after which it has firmly occupied the top position in sales, leading the entire bus industry in the field of new energy. In particular, Yutong accounted for about 90% of the total sales of plug-in hybrid buses in December last year.
Talking about the ISG hybrid system, Tang Yuxiang said that this technical route has very good business prospects. "This is similar to Honda's technology line. Yutong's plug-in hybrid bus has no gearbox and is completely superior to other technology routes in the market. The hybrid bus of this kind of system has a relatively low cost and the project is relatively good and has been fully demonstrated. There is still demand for such a car."
Yutong plug-in hybrid buses have gained market recognition
Zhongtong Bus also believes that the current maturity of new energy bus technologies has been greatly improved, and product performance is no longer comparable. Compared with traditional fuel buses, plug-in hybrid buses have a significant fuel saving effect. Li Tongsheng, Minister of Culture of Zhongtong Bus Enterprise, told the reporter: “In the past, hybrid buses could achieve fuel economy rates of 20% or even 30%. The current plug-in hybrid buses are more energy efficient than previous hybrid buses. Further improve."
Parts prices drop New energy bus costs drop
The increase in sales of new energy buses comes from demand and supply. On the one hand, customer demand will increase, and sales will, of course, increase. On the other hand, as prices decline, sales volume will increase.
This year, an obvious feature of new energy buses is the drop in vehicle prices caused by the sharp drop in parts prices.
Starting last year, the state’s subsidies for new energy buses have declined. In particular, the subsidies for hybrid buses have not only been reduced from the previous 420,000 yuan to 250,000 yuan, but also to the plug-in models with body lengths of 10 meters and above.
However, after the subsidy fell, users did not feel that the price of cars had risen. On the contrary, the prices of plug-in hybrid buses of some brands are lower than those of ordinary hybrid buses. Zhang Weilin said: “Hager's hybrid bus is worth more than 800,000 yuan. If the national subsidy of 250,000 yuan is subtracted, the actual price is only about 600,000 yuan, which is similar to the cost of an ordinary diesel bus, but its energy-saving performance is better. Many, because with the development of new energy passenger car parts and components in the past two years, the prices of many parts and components have been reduced, and the price of new energy buses has also been gradually reduced.â€
Li Shengsheng holds the same view: “The drop in the price of spare parts for hybrid buses comes from two factors: one is technical progress; the other is that with the increase in purchase volume, many fixed costs are diluted. Therefore, now Hybrid buses can be sold to users at a lower price than before, even with lower subsidies.†Li Shengsheng said that the price of Zhongtong plug-in new energy bus is about RMB 700,000, only after subsidy More than 500,000 yuan is almost the same as ordinary bus prices, but such vehicles have very good energy-saving and emission-reduction effects. Many demonstration cities naturally prefer to plug-in new-energy buses.
Tang Yuxiang believes that the state should vigorously promote new energy buses. “As far as ordinary hybrid buses are concerned, the cost that users spend on buying a car will run for several years, and the saved fuel money will make up for it.â€
Bus giants think: There will be great development of new energy passenger cars this year
New Energy Demonstration City Purchasing will force this year
In addition to the product's own factors, the three corporate executives believe that national policies also play a crucial role in the sales of new energy. Last year, the country began to announce new energy demonstration cities continuously, and made demands on the number of these cities to promote. This will promote the sales of new energy buses this year.
For the new energy market in 2014, which will significantly increase this, Sun Qingmin said: “In 2014, the hot spot of the passenger car market was still concentrated on new energy passenger cars and gas passenger cars. New energy passenger cars are moving towards rapid industrialization under the stimulation of national policies. It is expected that there will be a better market performance in 2014."
Li Shengsheng said such a reason: “Last year, the state ended ten thousand cities and began a new round of new energy demonstration city encouragement plan. This plan requires new energy demonstration cities to achieve certain promotion of new energy vehicles in 2013-2015. (Editor's Note: The requirements are 2013-2015, the total number of new energy vehicles in extra large cities or key regions will be no less than 10,000 vehicles, and the cumulative number of other cities or regions will not be less than 5,000.) This plan was just promulgated last year. The bus companies in many cities did not formulate procurement plans.The implementation period of this plan was from 2013 to 2015. By the middle of this year, half of the time had passed, but many cities did not act last year. Therefore, in order to accomplish these tasks, Many procurement tasks will be completed before the middle of this year, which means that there will be a better growth in the procurement of new energy buses this year.†Zhang Weilin also has the same view. “Because of the analysis of the policy, Hager also believes that the cities that did not purchase the demonstration cities last year and cities that did not complete the tasks will increase their procurement efforts this year.â€
However, both Zhang Weilin and Li Yusheng stressed: “Because subsidy is limited to a new batch of demonstration cities, the promotion of new energy buses is not easy for cities that have not entered the list.â€
