Bioplastics advantages because of its green low-carbon, a launch that is well received, but the reaction of the domestic market is very dull. "While technology and the cost of the bottleneck that hinders their development,plastic film but the main use of biological plastic, or because people lack awareness of environmental protection and the lack of government policy support." May 15 to 16 in Guangzhou, China held the Third International Bio Plastics application of the seminar, industry experts believe that by establishing production and research innovative alliance to the government, enterprises and associations and other forces are united, can achieve a breakthrough in technology and cost, coupled with policy support, such as to enhance the whole concept of environmental protection,color film to achieve market penetration. The news was received the news.
There is no doubt the rapid growth prospects
The experts pointed out that if the use of bio-plastic alternative to the traditional three synthetic polymer materials,pvc shower curtain can achieve the net number of tons of carbon dioxide emissions, so low-carbon economy in the implementation of bio-plastics will play an important role.
pvc plastic film Plastics Industry Association, Shenzhen, Guang Wang introduced a low-carbon bio-plastics, including biodegradable and non-biodegradable plastic, is currently being developed and realized the industrialization of bio-degradable plastics are six types, pvc color film natural polymer modified class, polyglycolic alkyl esters, aliphatic polyester, etc.; non-degradable and biodegradable plastic parts including polyester, nylon, starch / modified class of non-degradable plastics, fiber / plastic blends class and cellulose.
pvc film table cloth According to U.S. official statistics, the U.S. bio-plastics to grow 17% annually, is expected to reach 546,000 tons by 2012. European Bioplastics Association, predicts that the global bio-plastic production is expected to reach 1.46 million tons in 2013. Bio-plastic will keep the average annual growth rate of 20%. Asia 2025 will be the leader in bio-plastics market, accounting for 32% of the market share of 31% in Europe, the United States accounted for 28%. China's production of bio-plastic production in Asia will account for more than 40%, accounting for 12% of global production over time, China will become a major producer of bioplastics in Asia and the exporter.
Research technology to improve performance and reduce costs
While the broad market prospects, but the domestic market has been applauded not the latter, mainly due to the use of bio-plastic properties of some defects.
Low Carbon Innovation Alliance biological material production and research Deputy Secretary-General Zhang Xiangnan that natural polymer bio-plastics generally higher water absorption, processing performance is not good. Esters, such as polypropylene cross (PLA) brittleness, heat resistance is poor; polyhydroxyalkanoates (PHA) monomers during the fermentation of difficult to control, difficult to get stable performance of materials; carbon-based bio-plastic copolymer (PPC) poor heat resistance; Polycaprolacton plastic (PCL) low melting point (60 ℃), is difficult alone.
The face of bio-plastic properties of the defects, it is imperative for technology research, however, the strength of domestic research and development at present are not optimistic. Wang Kwong said that at present engaged in research and development in the field of universities and research institutes only dozens, forming bio-plastics processing technology, molding equipment, tooling, auxiliary materials, standards and testing, are not complete, bio-plastics market can not keep up fast growing demand, lagging behind in research and technology materials in the petrochemicals industry. Another problem is that universities and research institutions, scientific research can translate into timely, enterprises and research institutions are not well docking, lack of industrialization demonstration base and the security system and operation system.
In addition, the development has been plagued by the price of bioplastics is still difficult to solve the problem temporarily. Generally high prices of bio-plastics, such as PHA, PCL higher than the market price of more than 3 times the traditional general-purpose plastics. It is understood that large-scale domestic producers does not exceed 30, the production capacity from a few hundred tons to the tons of scattered distribution companies, power is relatively weak.
