WebNov 6, 2024 · Low-density polyethylene (LDPE): This is generated from free radical polymerization which leads to long and short branching of chains. This makes this type of polyethylene highly ductile but its tensile strength and durability are low. This commonly finds applications in plastic film wraps, grocery polythene bags, and slightly right plastic ... WebAug 17, 2024 · The term PP stands for polypropylene and the term LDPE stands for low density polyethylene. The key difference between PP and LDPE is that PP is a crystal-clear material, whereas LDPE is either translucent or opaque. Moreover, PP is a three-carbon chemical compound, while LDPE is a two-carbon chemical compound (the carbon atoms …
