CAS 67423-06-7 Polybutylene Succinate Adipate / Adipic acid-1,4-butanediol-succinic acid copolymer

PBSA (polysuccinic acid - butyl adipate) is a degradable plastic, generally made of fossil resources as raw materials, can be degraded by microorganisms in the natural environment, and the decomposition rate is higher than 90% in 180 days under compost conditions. PBSA is one of the categories with high research and application enthusiasm in biodegradable plastics.

PBSA is copolymerized from succinic acid, 1, 4-butanediol (BDO) and adipic acid (AA), which has better toughness and faster degradation rate than PBS. Costs can be reduced by adding calcium carbonate and starch. Its main use is also basically the same as PBS. Although PBS and PBSA were developed earlier, limited by their own properties and insufficient raw material succinic acid resources, the market consumption is far less than PBAT.
