PBS: Poly(butylene succinate)

If you have a PBS need, please complete this form with information on your volume, location and lead time requirements, and your target application. 


PBS is an aliphatic thermoplastic polyester typically produced from petrochemical feedstock, but can also be produced from bio-based ones. Its starting materials are 1,4-butanediol and succinic acid.

PBS has good biodegradability and impact toughness, excellent processability, good elongation at break, and good heat resistance. The temperature of PBS materials ranges from 30 C to 100 C. It has low flexural strength and modulus and, as such, can be blended with PLA to optimise its properties.
