Bio-Non-Woven Materials Polybutylene Succinate Bio-based Polymer Materials
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.
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%.
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.
