Environmental materials



PLA: Polylactic acid. It is a new type of Biobase and biodegradable material made of starch raw materials derived from renewable plant resources such as corn. Starch raw materials are gasified to obtain glucose, which is then fermented by glucose and certain strains to produce high-purity lactic acid, and then a certain molecular weight of polylactic acid is synthesized by chemical synthesis. It has good biodegradability and can be completely degraded by microorganisms in nature under specific conditions. It eventually produces carbon dioxide and water and does not pollute the environment. This is very beneficial to the protection of the environment and is a recognized environmentally friendly material.


PBS: Polybutanediol Ester. White particles, obtained by condensation polymerization of succinic acid and butanediol, are milky white, odorless and tasteless, easily decomposed and metabolized by enzymes in various microorganisms or plants and animals in nature, and eventually decomposed into carbon dioxide and water. It is a typical completely biodegradable polymer material. It has good biocompatibility and bioabsorption, good heat resistance, thermal deformation temperature and product operating temperature can exceed 100 °C. Its source of synthetic raw materials can be either oil resources or fermentation through biological resources. PBS is a leader in biodegradable plastic materials.


PCL: Polyhexolactone. It has good biodegradability, biocompatibility and non-toxicity, and is widely used as a medical biodegradable material and drug control release system. It can be used in tissue engineering as a drug sustained release system.


PHA: Polyhydroxyfatty acid Ester. It is a kind of intracellular polyester synthesized by many bacteria. It is mainly used as a storage material for carbon sources and energy in organisms. It has similar physical properties to synthetic plastics and many excellent properties such as biodegradability, biocompatibility, optical activity, piezoelectric, and gas separation that synthetic plastics do not have. Polyhydroxyfatty acid esters have broad applications in biodegradable packaging materials, tissue engineering materials, slow-release materials, electrical materials, and medical materials, but they can only be applied on a large scale if the production cost of PHA is reduced.


PBAT: Polyadipic acid/butyl terephthalate. PBAT is a thermoplastic biodegradable plastic. It is a copolymer of butanediol adipate and butanediol terephthalate. It has both PBA and PBT properties and has good ductility and fracture elongation. Good heat resistance and impact performance; In addition, it also has excellent biodegradability and is one of the most active biodegradable materials in biodegradable plastics research and market application.
