Effect of Different Types and Dosages of Chlorinated Polyethylene on the Properties of PP/CPE composite material
Different types of chlorinated polyethylene are used to modify polypropylene materials.The influence of these additives on the main properties of polypropylene composites was studied.Through blending modification research,the results show that different types of CPE have a significant impact on the notched impact strength,tensile strength,and elongation at break of polypropylene composites,especially on the low-temperature notched impact strength of polypropylene blends.Impact strength can be increased by more than 50%and the preferred dosage of CPE is 10 parts.If the dosage is too much,the compatibility with polypropylene will become significantly poor,which will lead to a downward trend in the performance of PP composites.
