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 is soft and has a tough feel, unlike hard plastics that are prone to cracking.
Good low temperature resistance, able to maintain good toughness at -60 ℃, suitable for freezing scenarios.
Strong chemical stability, resistant to most chemical substances such as acid, alkali, and salt, and insoluble in common solvents.
Excellent processability, easy to produce films, pipes, toys and other products through processes such as blown film and injection molding.
