Development of Specialized Resin for Metallocene Heat Shrink Film
The structure and performance of specialized resin for metallocene heat shrink film EZP2703 HH were analyzed by melt flow rate meter,full-automatic true density analyzer,dart impact tester,electronic tensile tester,high temperature gel chromatograph,nuclear magnetic resonance spectrometer,differential scanning calorimeter and haze meter,which were compared with similar imported products.The results show that the melt flow rate of the product is 0.30 g/10 min,the density is 0.927 g/cm3,and its mechanical property and processing property can reach the level of similar imported products,which can achieve equal substitution of imported products.A highly branched molecular structure is beneficial for improving the thermal shrinkage property of metallocene heat shrink film.
