Polymers are used in a variety of industries such as packaging, kitchen appliances, pipe and fittings, wires and cables, household appliances and automotive parts, and are commonly known as plastic. In order to improve their mechanical and visual features suitable additives such as fillers, pigment and reinforcements are used. Polyethylene (PE) which is a cheap, light and inactive solid, has excellent mechanical, electrical and chemical features and are producing in various density (HDPE representing high densities and LDPE representing low ones). HDPE has a stronger molecule band and the consequently higher strength than LDPE but the flexibility is lower. This Polyethylene is used in fabrication of milk and liquids containers, kitchen plastic facilities and water storages. Nowadays, Nano-particles are used in fabrication process so as to improve featured like shearing strength, impact strength, hardness and flexibility.
Adding Nano particles in high density PE polymer base substances has led to a considerable improvement in elongation and impact strength which is highly important in producing and consuming process. Decreasing of the tensile strength (UTS) is acceptable.
