PBS -- Full Biodegradable Resin

Posted:2016-12-06   Hits:1774  
Poly (1, 4-butanediol Succinate) (hereunder PBS) is a kind of fully biodegradable macromolecular polymer that is synthesized from succinic acid and butanediol through a direct process of condensation polymerization. On specific conditions, this material can be finally decomposed safely and innoxiously into simple compounds such as CO2, H2O, etc.

PBS has predominant characteristics such as good thermal stability, fine mechanical and processing performance. It can be molding processed in normal plastic fabrication apparatus. Because of its excellent integrated performance, it also can be blended with other fully biodegradable plastic materials to modify the property to satisfy all kinds of manufacturing requirements of plastic products.
