Fully Biodegradable Polymer Polybutylene Succinate Pbs Packaging Materials
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%.
Advantages of the product
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.
