With the rapid development of petrochemical industry, plastics industry began as an industry has developed rapidly. In recent years, plastic products are widely used in industry, agriculture, electronics, defense, construction and all areas of daily life, glue stick and as a raw material, and slowly began to replace steel, aluminum, wood and cement and other materials.
Since the new century, China's plastics plastic products industry in each of the national GDP growth rate higher than the growth in the beginning of 2008 the economic crisis hit, the entire plastics industry began to shrink, glue gun to the plastics industry in 2009 reached the lowest point of the development curve. Although the Government has taken a series of supporting policies, the plastics industry began recovering slowly, and showed varying degrees of growth. But the policy can only be as a support and guide the role of economic resources in the new world conditions, only to seize the opportunity, the courage to be innovative enterprises in this wave, the wind and waves, moving forward.
Therefore, the new plastic materials industry ready to come!
Biodegradable plastic is an inevitable trend.
In today's increasingly tight supply of global oil resources, petroleum-based raw materials, synthetic plastics environmental problems caused by the increasing prominence of the situation, bio-degradable plastic base and market demand is growing rapidly. December 2009 in Copenhagen, "low-carbon economy" become the focus of hot, renewable resources as raw materials to manufacture bio-based materials is by the world's attention as the development of a large family of plastic hot.
Degradable plastics in the use of renewable energy, alternative petrochemical resources; reduce carbon dioxide emissions, combating the greenhouse effect; to promote environmental protection and reduce the white pollution; partial solution to rural issues; break barriers to trade; improve the enterprise, industry image, and so play an important role, is integral part of sustainable development, the plastics industry.
At present, bio-degradable materials are natural products, polymers, carbon dioxide copolymer, poly hydroxy fatty acid ester (including PHB and PHBV, etc.), polylactic acid, polycaprolactone, succinate and so on. Biodegradable plastics in 2009, about 180 more than the enterprise, the production capacity of about 10 tons / year, actual production of about 5 tons.
Degradable plastic enterprises want to have food to eat on the plastics market, it should promote the bio-based biodegradable plastic raw materials production, processing technology to enhance and expand the production scale of natural polymer materials to meet the growing needs. Biosynthesis of non-grain raw material polylactic acid, polyhydroxyalkanoates such as bio-based degradable plastics, synthetic expansion of other chemical production of biodegradable plastics, starch-based plastics and other materials to improve the blend processing technology, ensure that enterprises in the production and application of degradable plastics a leading position.
Modified plastics to help the plastics industry out of the doldrums.
Modified plastics is through the common plastics processing are flame retardant, high impact plastic and other special properties. Today, more and more areas of the application of plastic materials widely used in plastic and place where all can be used to enhance the performance of modified plastics.
Crude oil down along the industrial chain, modified plastics in the most at the end, it is the fastest growing demand, the highest rate of return on investment links. Modified plastics have been widely used in current cars, home appliances, electrical and electronics, light industry, and military industries, and has seized part of the application of traditional engineering plastics market, a variety of high-strength heat resistant engineering plastics will be widely used. Polyphenylene sulfide (PPS), polyimide (PIM), polysulfone (PSF) and other high performance engineering plastics in the petrochemical, aerospace and other cutting-edge rocket and increasingly important field of application. Expected in the next 5 to 10 years, the total demand for modified plastics market will remain more than 10% annual growth.
Unstoppable in the development of modified plastics, when production capacity of modified plastics preached the phenomenon. 2009 production of plastic resin has reached 33 million tons, while domestic consumption accounts for plastic resin modified plastics consumption is less than 10%. At present there are thousands of companies engaged in the modification of plastics production, but production capacity of more than 3000 tons, only 70 or so total capacity is 168 tons.
The production capacity from the development of modified plastics business of scale, product range, technology, and are in a relatively backward state. The focus of the development of modified plastics technology. Because of a modification of plastic can have a variety to get different functional material, increasing value-added products, and raw materials, equipment and other costs have not increased significantly, completely rely on innovative technologies to support product development. Therefore, the development of technology has become key to the development of modified plastics.
