Polybutylene Succinate PBS

White particles, polyethylene glycol butyl diacid butyl ester (PBS) by succinic acid and butyl glycol by condensation polymerization of synthetic, resin in milky white, odorless, vulnerable to a variety of microorganisms or plants and animals in nature of the enzyme catabolism, eventually decomposed into carbon dioxide and water, is typical of completely biodegradable polymer material has good biological compatibility and biological absorbability;Density of 1.26 g/cm3, melting point 114, according to the high or low molecular weight and molecular weight distribution, crystallinity between 30 ~ 45% in the 1990 s it into the material research field, and quickly became can be widely applied in the universal one of research hotspots of biodegradable plastic materials, heat resistant performance is good, heat distortion temperature, and the products using the temperature can exceed 100 synthetic raw material sources can be either its oil resources, also can through fermentation by biological resources, PBS are outstanding in biodegradable plastic materials.
