Classification of bio-based materials: There are many categories and subdivisions of bio-based materials
According to product attributes, bio-based materials can be divided into bio-based polymers, bio-based plastics, bio-based chemical fibers, bio-based rubber, bio-based coatings, bio-based material additives, bio-based composite materials and various bio-based materials. obtained products, etc. Among them, bio-based degradable materials have green, environmentally friendly, renewable and biodegradable characteristics that traditional petroleum-based plastics and other polymer materials do not have; bio-based fibers have been widely used in fashion, home, outdoor and industrial fields. It is gradually moving towards the stage of industrial-scale practical application and industrialization; bio-based plastic products have been well applied in the fields of packaging materials, disposable tableware and shopping bags, baby diapers, agricultural mulch films, textile materials, etc., and are generally recognized by the market. accept.
According to common product forms, bio-based materials can be mainly divided into five categories: bio-based platform compounds, bio-based plastics, polysaccharide-based bio-based materials, amino acid-based bio-based materials, and wood-plastic composite materials. Among them, bio-based platform compounds are chemical monomers that are polymerized into raw material polymers, such as lactic acid, 1,3-propanediol, etc. Bio-based plastics are currently the most widely used and well-researched bio-based materials, and representative products include polylactic acid, Polyhydroxyalkanoates, etc.
