Predicting LLDPE Blown Film Properties with Statistical Design of Experiments

摘要

The development of new antiblock minerals may require the evaluation of several or more factors such as antiblock type, median particle size, loading level, etc. These factors can have large effects on film properties. Comparison and ladder studies can generate adequate experimental data for a single factor. The number of experiments required for the evaluation of three or more factors quickly becomes large. Fractional factorials can significantly reduce the number of experiments and provide direction for the future experiments. This paper studies the affect of antiblock median particle size, antiblock loading, slip loading and film thickness on LLDPE blown film properties. Film properties analyzed include haze, clarity, gloss, blocking, reblock and COF.
