With the rise of energy prices and the increasingly obvious ecological and environmental problems, the pace of replacing traditional petroleum products with biodegradable biomaterials around the world shows a slowly accelerating development trend. It is expected that government agencies will also implement corresponding preferential policies and relevant laws and regulations to encourage application fields. The large-scale application prospect of biodegradable materials is very optimistic.
The biolytic material comprises a polymer material which is immediately manufactured by biotechnology such as polyhydroxyfatty acid ester; Raw materials for biotechnological manufacturing such as polylactic acid, polybutylene succinate and glycan; In addition, some starch based biodegradable plastics, carbon dioxide prepolymer, alicyclic polypropylene, etc.
Starch based biodegradable plastic is an injection molding product made by blending starch with other polymers after modified materials and thermal polymerization. It can replace general plastic raw materials in industrial production and can be used as packaging materials, seismic grade materials, agricultural film, food packaging materials, toys, etc.
PLA is a high molecular material gathered and converted from lactic acid bacteria beverage. It has the characteristics of no toxicity, high tensile strength, easy processing and molding and high-quality biocompatibility. The goods can be dissolved after use. Therefore, PLA is a biological ecological environment protection material that can truly ensure the dual effects of ecological environmental protection and social and economic development, In recent years, it is a biodegradable plastic with design and development activities and rapid development trend.
Butanediol succinate is obtained from succinic acid and butanediol according to the folding reflection. It is now recognized as a biodegradable plastic with good comprehensive performance. Due to its excellent comprehensive performance, reasonable cost performance and wide application range, PBS can be used in packaging, kitchen supplies, cosmetic bottles and drug bottles, agricultural machinery plastic film, organic fertilizer and organic fertilizer initial setting materials, biological diagnosis and treatment polymer materials and other fields.
Polyhydroxyfatty acid ester belongs to high molecular polyester, which is an intracellular polyester produced by many pathogenic bacteria under special circumstances. At present, more than 90 genera of pathogens have been found to be able to transform into more than 150 kinds of PHA with different structures. At present, the important commercial PHA products include Polyhydroxybutyric acid, prepolymer of hydroxybutyric acid and hydroxyvaleric acid, and prepolymer of hydroxybutyric acid and hydroxycaproic acid.
