Poly butylene succinate

 any questions please feel free to ask us

Succinic acid, a raw material of synthesizing PBS.

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)

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