Polybutylene succinate (PBS) is is synthesized via one-step condensation of 1, 4-butylene glycol and succinic acid.

Polybutylene succinate

Biodegradable plastic——True green & environment friendly

PBS is synthesized via one-step condensation of 1, 4-butylene glycol and succinic acid. In

compost, PBS is non-toxic and it can degrade or decompose into CO2 and H2O, etc. It is

different from the composite of common plastics with starch which is fake biodegradable

plastic. It is the true green and environment friendly material.

Characteristics

PBS is crystallized biodegradable polyester. Its pellets are white or weak yellow. It have

high mechanical performance, good toughness, good thermal stability, wide range of

processing temperature and high heat deflection temperature. It can be processed by various molding way with normal equipments. So it has excellent comprehensive properties. To meet the requirements of various products, it can be mixed with other biodegradable or natural materials, such as PLA, PPC, PHAs, PCL and starch or wood powder.

Applications

 Injection grade (One-time Tableware, Engineering Components)

 Extrusion grade (Blending Modification, Sheet,)

 Blowing grade (Film, Bottle and Soft Tube)

 Blister molding grade (Inner Package, Tableware)

 Fiber

It can be used in packaging, tableware, engineering, medicine, agriculture, releasing and

ecological materials.
