HDPE (High Density Polyethylene) is a widely used thermoplastic. It is created by copolymerizing ethylene with a small amount of alpha olefin monomer, and is commonly referred to as low-pressure polyethylene because it is produced under lower pressure. HDPE has a predominantly linear molecular structure with few branches, high crystallinity, and high density.
When it comes to its physical properties, HDPE is a non-toxic, odorless, and tasteless white particle with a melting point of around 130°C and a relative density ranging from 0.941 to 0.960. It exhibits good heat and cold resistance, maintaining optimal performance within a temperature range of -40°C to 100°C.
Turning to its chemical properties, HDPE demonstrates good chemical stability and remains insoluble in any organic solvents at room temperature. It shows resistance to acid, alkali, and various salt corrosion, though it can be dissolved in hydrocarbon solvents above 60°C.
As for its mechanical properties, HDPE boasts high rigidity and toughness, excellent mechanical strength, remarkable stress cracking resistance, superior wear resistance, and a service life approximately four times longer than that of steel pipes in water environments.

In the field of packaging, polyethylene terephthalate (PET) can be utilized for manufacturing plastic bottles, films, and various other related products. When it comes to pipe materials, PET is commonly used for gas pipes, drinking water pipes, and other applications. Additionally, PET can play a crucial role in producing everyday essentials, industrial products, and more through injection molding techniques. Moreover, it is also instrumental in creating wrapping materials and synthetic paper specifically designed for wires and cables.
