Bio-based polybutylene succinate (PBS)

Shandong Landian biological Technologies Corporation Limited was founded in 2012, with registered capital 220 million yuan. The company is located in Shandong Province, Shouguang, Yangkou high-tech Industrial Park. The company has three phases of "the construction non-grain materials 500000 tons / year of succinic acid and bio based products PBS industrialization project", equip with succinic acid fermentation system, separation and extraction system, esterification and hydrogenation of butylene glycol system, PBS polymerization system and power plant, sewage treatment plant, office, living area, covers the area of 1500 mu. The main products are 1,4-succinate, butanediol, polybutylene succinate (PBS) etc. This project total finds is 5.58 billion yuan and the project total investment 5.02 billion yuan. The project will realize annual sales income of 10 billion yuan(including tax), total profit and tax 3 billion yuan, providing 1000 jobs, with significant economic and social benefit.

Product Features: White particles, density 1.26g/cm, melting point 114°C, crystallinity between 30~45%; milky white, odorless, easy to decompose.

Bio-based polybutylene succinate (PBS) is a typical fully biodegradable polymer.

Application: Can be used to produce environmentally friendly degradable plastic products, agricultural film, disposable medical products, biomedical polymer materials, packaging materials, disposable tableware, cosmetic bottles, bio-fibers, bio-foam materials, bio-nonwovens materials and so on.

Advantages of the product: Based on the bio-based succinic acid produced by our company as a raw material, the bio-based PBS produced by the processes of esterification and polycondensation is a bio-based polymer material encouraged and advocated by the country. With the disposable products produced by this product, complete biodegradation can be achieved by microorganisms in nature. At present, EU countries, such as France and the United Kingdom, have successively banned the use of non-biodegradable materials and forced the use of biodegradable materials. Therefore, bio-based PBS will become a popular degradable material.

(2) 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.

Product description and advantages

White granules, polybutylene succinate (PBS) obtained by the condensation polymerization of succinic acid and butanediol. The resin is milky white, odorless and tasteless. It is easily assimilated by various microorganisms in nature or enzymes in plants and animals. Decomposition, metabolism, and finally decomposition into carbon dioxide and water are typical biodegradable polymer materials. Has good biocompatibility and bioabsorbability; density 1.26g/cm3, melting point 114 °C, according to the level of molecular weight and molecular weight distribution, crystallinity between 30 to 45%.

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.
