Polybutylene Terephthalate (PBT)

We are the Synchemia Research Chemical specializes in manufacturing and exporting of PBT CYCLIC DIMER or Cyclobis(1,4-butylene terephthalate),PBT CYCLIC TRIMER or Cyclotris(1,4-butylene Terephthalate),PBT CYCLIC TETRAMER or Cyclotetrakis(1,4-butylene Terephthalate),PBT CYCLIC PENTAMER or Cyclopentakis(1,4-butyleneTerephthalate) and PBT CYCLIC HEXAMER By specializing in the synthesis and export of these PBT compounds, Synchemia Research likely plays a significant role in supporting the pharmaceutical industry's efforts to meet regulatory requirements and ensure the highest standards of quality and safety in drug manufacturing.

PBT, or Polybutylene terephthalate, is a semi-crystalline thermoplastic compound used for engineering purposes. It possesses a composition and properties that are similar to that of PET (Polyethylene Terephthalate).PBT is in the polyester polymer family. This material is formed by a process called polycondensation, which uses terephthalic acid. It can also be formed using dimethyl terephthalate and 1,4-butanediol
