Biodegradable PLA stics have a wide range of applications and broad market development potential

Since the application of biodegradable PLA stics in the high-end market mainly includes medical supplies, drug slow-release materials,3Dprinting materials, etc. and PLA ,PCL,PHAsSuch biodegradable PLA stics have good biocompatibility, and can realize the controllability of performance through molecular design during synthesis, so they have development potential in the high-end market.polylactic acid ( PLA )Polylactic acid is a polymer obtained by polymerizing lactic acid as the main raw material, and it is a commercialized bio-based degradable PLA stic.The main raw material lactic acid is obtained from cornstarch, and can also be made from sugar beets or grains to reduce costs. The raw materials for the production of polylactic acid are abundant and renewable, the production is pollution-free, and the product can be biodegraded.Polylactic acid has good biosolubility, bioabsorbability and good solvent resistance, and can be processed in various ways, such as blown film, extrusion molding, etc.Polylactic acid also has good flame retardancy and antibacterial properties, and among degradable thermo PLA stic polymers, PLA It has the best heat resistance, so it can be melt-spun with conventional processing technology without special equipment and operation technology.In conclusion, in the next few years, the market demand for biodegradable PLA stics will grow rapidly and is expected to2020The total global demand for biodegradable PLA stics will reach322About 10,000 tons, the average annual growth rate of demand exceeds16%.Since biodegradable PLA stics are widely used and have great value in medical treatment, production, and manufacturing, it is an effective solution to vigorously develop biodegradable and environmentally friendly PLA stics industries.”White pollution”problems, avoiding the hazards of PLA stic and its cancer risks, and the best ways to protect the environment.
