LDPE (Low Density Polyethylene) is a thermoplastic material made from ethylene through high-pressure polymerization process. Due to the large number of short branches in its molecular chain, it has the characteristics of softness, impact resistance, and easy processing.
1. Core raw material composition
Main raw material: Ethylene
Derived from petroleum or natural gas, extracted through processes such as ethane steam cracking and naphtha cracking, it is the basic unit that constitutes the LDPE molecular chain.
Auxiliary raw materials
Catalyst (free radical initiator): such as benzoyl peroxide, triggers the polymerization of ethylene molecules, determining the reaction rate and polymer molecular weight.
Additives: added as needed to optimize performance, commonly including antioxidants (anti-aging), lubricants (easy to process), anti adhesion agents (preventing finished products from sticking), coloring agents (adjusting color), etc.
The texture of this material is soft yet tough, distinguishing it from hard plastics that are more susceptible to cracking.
It exhibits excellent low temperature resistance, retaining its toughness even at -60 ℃, making it well-suited for freezing environments.
With its strong chemical stability, it can withstand exposure to various chemicals, including acids, alkalis, and salts, remaining insoluble in common solvents.
Furthermore, its outstanding processability enables easy manufacturing of items like films, pipes, and toys using methods such as blown film extrusion and injection molding.

In the packaging field, plastics are commonly used with the highest proportion. This includes applications such as food wrap, shopping bags, waterproof express bags, and the inner layers of composite packaging bags.
In daily necessities, plastic finds its use in various items like hoses (such as toothpaste tubes), toys, plastic covers, and disposable gloves.
Within the industrial field, plastics are utilized as the insulation layer for wires and cables. They also play a crucial role in agricultural applications such as agricultural film for insulation and moisture retention.
