AIE PBT Plastic Raw Materials

الوصف

PBT is one of the toughest engineering thermoplastics, it is a semi-crystalline material, and has a very good chemical stability, mechanical strength, electrical insulating properties and thermal stability. These materials have a good stability in a very broad environmental conditions. PBT weak hygroscopic properties. The tensile strength of the non-reinforced PBT to *0MPa, and the the glass additive type PBT tensile strength **0MPa. The glass additives too much will cause the material to become brittle. PBT; crystalline very quickly, and this will lead to the bending deformation is caused due to the uneven cooling. For a material with a glass additive type, the flow direction of the shrinkage can be reduced, but with the shrinkage of the vertical direction of the process substantially no difference and general material. Between general material shrinkage in the 1.5% to 2.8%. Between a contraction of 0.3% to 1.6% of a material containing *0% of glass additive. Melting point (**5 ℃) and high temperature deformation temperature than PET material. The Vicat softening temperature of about **0 ° C. The glass transition temperature (glass trasitio temperature) of between *2 ° C to *3 ℃. Due to the high crystallization rate of PBT and therefore its viscosity is very low, the cycle time of the plastic parts processing is generally low.
