Fully Biodegradable Polymer Polybutylene Succinate Pbs Decomposable
Bio-based polybutylene succinate (PBS)
Based on the bio-based succinic acid produced by our company as a raw material, through esterification, condensation and other processes forms Bio-based polybutylene succinate (PBS).
That is a bio-based macromolecular material encouraged and promoted by the state. The disposable products produced by this product can be completely biodegradable through the microbes in nature. At present, eu countries, such as France and the UK, have legislated to ban the use of non-biodegradable materials and to enforce the use of biodegradable materials. Therefore, bio-based PBS will become a popular degradable material.
Application range
Polybutylene succinate (PBS) can be used as garbage bags, packaging bags, cosmetics bottles, various plastic cards, baby diapers, agricultural materials, and drug release carrier matrix; there are other related to environmental protection Kinds of plastic products, such as landscaping nets and membranes. Polybutylene succinate (PBS) can be used for packaging, tableware, cosmetics bottles and pharmaceutical bottles, disposable medical supplies, agricultural films, pesticides and fertilizers sustained-release materials, biomedical polymer materials and other fields.
Molding method
Polybutylene succinate (PBS) is a thermoplastic resin and has good processing properties. It can be processed on ordinary processing equipment. The processing temperature range is 140~260°C. The material must be dried prior to processing. The moisture content must be below 0.02%.
Polybutylene succinate (PBS) can be processed by injection molding, blow molding, blown film, blister, lamination, foaming, spinning and other molding methods.
Polybutylene succinate (PBS) is a polymer with good biodegradability. Compared with polylactic acid, polyhydroxyalkanoate, polycaprolactone and other biodegradable plastics, PBS is relatively low in price. Excellent mechanical properties, good heat resistance, heat distortion temperature close to 100 °C.
