Effect of Sample Preparation on Determination for Melting Temperature of Polypropylene Pipe Material Utilizing Differential Scanning Method

Utilizing two different ways to obtain polypropylene pipe materials, that is palletizing method and tabletting method, after that using differential scanning method for the determination of melting temperature, at last analysis the effect of different sample preparation methods for melting temperature based on obtained data. Experiment results showed that, melting temperature of sample prepared by palletizing method was higher, but sample prepared by tabletting method had good repeatability.
