Self-Extinguishing HD Polyethylene for Opaque and Durable Packaging Solutions

Product Description:

HDPE (High Density Polyethylene) is a widely used thermoplastic with various characteristics:

HDPE is produced by copolymerizing ethylene with a small amount of alpha olefin monomer. It is also referred to as low-pressure polyethylene due to its synthesis under lower pressure. The molecular structure of HDPE is predominantly linear, with minimal branching, high crystallinity, and high density.

HDPE appears as a non-toxic, odorless, and tasteless white particle with a melting point of approximately 130 ℃ and a relative density ranging from 0.941 to 0.960. It exhibits excellent heat and cold resistance, maintaining performance between -40 ℃ and 100 ℃.

HDPE demonstrates good chemical stability and remains insoluble in any organic solvents at room temperature. It resists corrosion from acids, alkalis, and various salts; however, it can dissolve in hydrocarbon solvents above 60 ℃.

HDPE possesses high rigidity, toughness, and mechanical strength. It showcases exceptional stress cracking resistance, outstanding wear resistance, and a lifespan in water environments that is four times longer than that of steel pipes.

Applications:

In the field of packaging, polyethylene is widely used for manufacturing plastic bottles, films, and other packaging materials. It offers versatility and strength for various packaging applications. When it comes to pipe materials, polyethylene is commonly used for gas pipes, drinking water pipes, and other types of pipes. It is valued for its durability, corrosion resistance, and flexibility in piping systems. Polyethylene can also be utilized in the production of daily necessities, industrial products, and more through injection molding processes. Its capability to be molded into various shapes and sizes makes it a versatile material for diverse manufacturing needs. Furthermore, polyethylene can be applied in creating wrapping materials and synthetic paper used for wires and cables. Its properties make it suitable for providing protective covering and insulation in electrical applications.
