Wuhan Handern Biodegradable Film
Japan's Mitsui Toatsu Chemical Company recently launched the world's first biodegradable plastic directly polymerized by lactic acid. After the lactic acid is converted into another compound, it uses a special solution and a catalyst for directional polymerization to produce the world's first A transparent biodegradable plastic. www.handern.com The new production method of plastic building templates is called the MTC method, which uses grain fermentation to produce lactic acid. The lactic acid is polymerized at a pressure of 100 to 200 ℃ to become a polymer of 100,000 to 200,000 molecular weight. This polymer can be injected 3. Extrusion blown film with good film strength and transparency. At present, the company uses it to produce daily necessities such as bottles and films. If the waste and compost are mixed within 10 to 20 days, all of them can be biodegraded into H2O and CO2. www.handern.com Plastic building template
A British chemical company produces a new type of plastic called PHB, which is a bacterium cultivated from sugar, and then use this bacterium to make a plastic. Its performance is similar to P. It is completely biodegradable and non-toxic. Used in food and medicine packaging and surgical sutures www.handern.com Plastic building template
The use of starch dry base material to join into PE and other plastics to make a film can accelerate biodegradation. The amount of starch in plastics is currently 15 to 30%, but there is already an American company that can make plastics containing 90% starch. And another American company can make plastic film with 100% starch. In 1995, the world starch plastic output will reach more than 1 million tons. www.handern.com Plastic building template
Japan Showa Polymer Co., Ltd. developed and produced a biodegradable plastic called Bionolle through the polycondensation reaction of ethylene glycol and dicarboxylic acid. In 1993, a plant with an annual output of 3,000 tons was built in Hyogo, Megmoto. Sheets, foam products, etc. At this time, 50% corn starch can be blended in this plastic, which has good biodegradability. When corn starch is used to mix with plastics, the plastic should be modified to make it compatible with starch, otherwise there will be no good performance results. www.handern.com Plastic building template
