Influence of PNA012 on Crystallization and Mechanical Properties of Polybutylene Terephthalate
PNA012 is a new nucleating agent on polybutylene terephthalate.The effect of different dosage of PNA012 on crystallization and mechanical properties were investigated by means of differential scanning calorimetry,universal testing machine,melt flow indexer and vicat softening testing machine.It was revealed that the PNA012 could substantially accelerate the crystallization of PBT.Compared with the pure PBT,the crystallization temperature of PBT/PNA012 rises from 196.3℃ to 199.7℃ and crystallization degree from 34.2% to 39.9%.The tensile strength of PBT/PNA012 is increased 9.7%.The bending strength has a rise of 9.3% and the heat distortion temperatures of PBT/PNA012 is increased from 115.07℃ to 125.94℃.
