Virgin PBT Plastic Resin
Chemical and physical properties of PBT polybutylene terephthalate
PBT is a tough engineering thermoplastic, it is a semi-crystalline material with very good chemical stability, mechanical strength, electrical insulating properties and thermal stability. These materials are very stable under a wide range of environmental conditions. PBT has weak hygroscopic properties. The tensile strength of unreinforced PBT is 50MPa, and the tensile strength of glass additive type PBT is 170MPa. Too much glass additive will cause the material to become brittle. The crystallization of PBT is rapid, which will cause bending deformation due to uneven cooling. For materials with glass additives, the shrinkage in the process direction can be reduced, but the shrinkage in the direction perpendicular to the process is basically the same as that of ordinary materials. The general material shrinkage rate is between 1.5% and 2.8%. Materials containing 30% glass additives shrink between 0.3% and 1.6%. Melting point (225% ℃) and high temperature deformation temperature are lower than PET material. The Vicat softening temperature is about 170°C. The glass transition temperature is between 22°C and 43°C. Due to the high crystallization rate of PBT, its viscosity is very low, and the cycle time of plastic parts processing is generally low.
