Climate Conference in Copenhagen is becoming a low carbon automotive industry started origin. Low-carbon economy has become the focus of attention behind the scene one of the topics.
Guangzhou Motor Show in the recently concluded, almost every exhibitors in low-carbon, energy saving, emission reduction initiatives in varying degrees, more than 60% of the car firms involved in corporate strategy aspects of the new energy vehicle development program. The low-carbon vehicles, in addition to plot new energy, foam,glue stick plastics used in automobile industry is the general trend and popular feeling.
In order to meet the needs of automotive industry, automobile plastic expanding the variety and range of applications. 90 20th century, developed countries average car plastic volume is: 100 ~ 130kg / units, accounting for vehicle curb weight of 7% to 10%; to 2002, developed countries, the average plastic car reached 300kg / and more vehicles, accounting for 20% of vehicle curb weight. 2020, developed countries, the average plastic car will reach 500kg / and more vehicles.
China's economy car vehicle plastic dosage 50 ~ 60kg; Light and medium trucks of plastic consumption is only 40 ~ 50kg; heavy-duty trucks of up to about 80kg. China, the limousine for the developed countries to introduce the basic model, glue gun the amount of automotive plastics applications and developed the basic level is very 90's of last century, to 100 ~ 130kg / vehicles.
Plastics in a wide range of automotive applications, according to the functions applied are divided into three categories: interior parts, exterior parts, function structure.
Exterior parts: plastic and steel to increase the amount of plastic products, applications, reduce vehicle weight to save energy. Such as bumpers and so on.
Interior parts: the safety, environmental protection, comfort features for the application, can absorb impact energy with the energy and vibration elastomers and foam plastic manufacture instrument panels, seats, headrests and other products, to reduce collision damage on the human body, improve the car's safety factor.
Functional structure: multi-use high-strength engineering plastic, to reduce weight, reduce costs, simplify processes. Such as a plastic fuel tank, engine and chassis number of parts and so on.
China's auto market recently can be described as weak in the global auto market booming up contrarian case, as the ten industrial revitalization program auto industry, auto industry in the car to the countryside and the revitalization plan unveiled details of a positive factor for the lead, sales volume is climbing, and even the economic crisis were not much more than the same period of last year's sales. However, the weakness in the global automotive market can not be ignored, decline in demand led to the Japanese car exports to the U.S. 18th consecutive monthly decline, a decline of 58% to 556.5 billion yen, Japanese exports to the EU is also the 7th consecutive monthly decline, on EU exports were down 55%, to 491.3 billion yen. Japan's exports to China dropped 40%, to 611.8 billion yen, due to the Chinese market for automotive, plastics, semiconductors and other electronic components of the demand has dropped significantly.
January 2009, when automotive plastic parts suppliers Craaytech bankruptcy, becoming the sagging North American automotive market, another victim, less than two months later, in March 2009, the European leading supplier of automotive plastic parts Plastal announced bankruptcy, because demand for natural also because of the sharp decline in auto industry, Plastal major European automotive plastic parts and components suppliers, with 2008 sales of 1.3 billion euros. When people are distraught sigh, can not help but start to think, in the end how to make plastic parts out of the winter?
On the one hand and plastic parts in automotive applications (Source Global polyurethane network) can effectively reduce the body weight to achieve lighter vehicles to save fuel, energy conservation is an important vehicle to achieve one of the ways. Use of plastic itself is recyclable, so the recycling of auto parts automotive plastics industry is a top priority for sustainable development in energy conservation, promote environmental protection, to speed up a harmonious development of great significance.
Automotive plastic parts can be recycled as spare parts, auto industry to achieve sustainable development of the necessary factors. Today, recyclable automotive plastic parts research and development in this area has been the country attaches great importance to vehicle manufacturers, and would like to market weakness in the global automotive environment, survival and development of large, recyclable plastic parts and components in terms of R & D is essential. On the other hand is the development of new products, automotive plastic applications, such as Toyota, to look full of bioplastics that use of vehicles by 2015, the plastic will 20% (mass ratio) the replacement of biological plastic. Change made to achieve the ratio of the front, also need to heat-resistant bioplastic, forming resistance, impact resistance and long-term reliability issues to achieve technological breakthroughs. Toyota has begun to advance the Improvement of the above topics. Currently, the car used in the proportion of various plastics: polypropylene (PP) less than 50%, polyvinyl chloride (PVC), polyurethane (PU) and the main material ABS resin about 80% of the total accounted for. 2015 Toyota plans to gradually replace these plastic bio-plastics. First of all bio-plastics will replace the car interiors.
In the United States and Europe, 30% -40% of plastic consumption is concentrated in the automotive field; engineering plastics market in China the consumption ratio, car usage has been accounted for 11.82%, followed by electrical and electronic, after (the share of consumption ratio of 30.4 %). Thus, industry analysts say, with the automotive industry in recent years, the rapid demand for plastic, plastic industry and the automotive industry in China has become "a prosperity, a loss for both sides" of the situation. As the automotive body, interior, bumpers and even various types of engines are widely used plastic, plastic industry will also be accompanied by the domestic automobile industry to stimulate the development of policy can usher in a new peak should be anticipated.
