What are the main characteristics of engineering plastics PBT is?
2015-06-17 Reads : 43
There are many types of engineering plastics, generally, we production and life are relatively common, engineering features and advantages are better, that is why it is often used today, we have to this material PBT Simply explain the advantages and performance characteristics under engineering plastics. In many people's opinion, PBT is one of the toughest engineering plastics. It is a semi-crystalline materials, has very good chemical stability, mechanical strength, electrical insulating properties and thermal stability. In a wide environmental conditions have a very good stability of these materials. PBT weak absorption characteristics. Non-reinforced PBT tensile strength of 50MPa, PBT tensile strength of the glass additive type of 170MPa. Glass fillers make the material brittle. PBT crystallization very quickly, which would result in uneven cooling caused by bending deformation. For glass additive type of material, flow direction shrinkage can be reduced, but the process of shrinkage in the vertical direction and substantially no difference between ordinary materials. General material shrinkage of between 1.5% to 2.8%. Material containing 30% glass additive contraction of 0.3% to 1.6% between. Melting point (225 ℃) and heat distortion temperature is lower than that of PET. Vicat softening temperature of about 170 ℃. Glass transition temperature between 22 ℃ to 43 ℃ (glass trasitio temperature). Due to the high crystallization rate of PBT, so it's a very low viscosity, plastic processing cycle time is generally low.
