What is Thermoplastic Polyester (PBT)?


                                                                                                    What is Thermoplastic Polyester (PBT)?  

                                                                           Polybutylene terephthalate (PBT) is a very strong engineering thermoplastic polymer with extremely

                                                                           high electrical properties, heat resistance and very good dimensional stability. Its semi-crystalline

                                                                           structure and chemical composition can withstand Resistant to many chemicals, oils and greases. 

                                                                           And PBT has good compatibility with various reinforcing materials, flame retardant materials and

                                                                           other additives. We at UNINKO can give the material more properties to enrich customers' diverse 

                                                                           application scenarios.

                                                                                                     PBT Technical Attributes:

                                                                                                        · Hard, rigid and strong 

                                                                                                        · Continuous use temperature to 140℃

                                                                                                        · Very high heat distortion temperature (HDT),especially for glass fiber reinforced grades

                                                                                                        · High dimensional stability 

                                                                                                        · Good creep resistance

                                                                                                        · Good chemical & stain resistance

                                                                                                        · Good weathering resistance

                                                                                                        · Good paintability & printability

                                                                                                        · Rapid crystallization & fast cycle time

                                                                                               PBT can be modified in the following aspects?

                                                                      ·Reinforcement modification: Reinforcing agents such as glass fibers, carbon fibers, mineral fillers, etc., can be added to PBT to improve

                                               its strength, rigidity, and impact resistance. The addition of reinforcing agents makes PBT more suitable for applications that require high 

                                               strength and rigidity.

                                                                      ·Thermal stability modification: By adding heat stabilizers or antioxidants, the thermal resistance and stability of PBT can be improved, 

                                               allowing it to maintain good performance in high-temperature environments.

                                                                      ·Flame retardant modification: Flame retardants can be added to PBT to enhance its flame retardant properties, making it meet specific 

                                               flame retardant requirements. This is particularly important for applications in electronics, electrical appliances, and automotive industries, 

                                               especially in environments where fire hazards exist.

                                                                      ·UV resistance modification: By adding UV stabilizers, the UV resistance of PBT can be improved, extending its service life in outdoor

                                               environments and reducing color changes and surface aging issues.

                                                                      ·Conductive modification: By adding conductive agents such as carbon black or metal powders, PBT can be made conductive for applications

                                               in electrostatic protection or electromagnetic shielding.

                                                                      ·Improved chemical resistance: By adding additives that enhance chemical resistance, PBT's resistance to corrosive media such as acids, 

                                               alkalis, solvents, etc., can be improved.

                                             These modification methods can be selected and combined based on specificapplication requirements and performance needs to meet the demands

                                             of specificindustries.
