| Abstract: | Effects of talc powder on crystallization behavior and mechanical property of Polyethylene terephthalate （PET） are studied by using differential scanning calorimetry and universal electronic tensile testing machine. The results indicate that talc powder can considerably improve the performance of PET. When the dosage of talc powder is 5wt%, the comprehensive performance of materials is the best, the half crystallization time is shortened by 47.0%, the tensile strength is improved by 22.2%, the flexural strength is improved by 57. 8%, and the impact strength is improved by 36.6%. |
