Product Description:

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.

Applications:

Packaging Field: This includes items like food wrap, shopping bags, waterproof express bags, and inner layers of composite packaging bags, which make up the largest proportion in this industry. These products are essential for protecting and containing various goods during storage and transportation.

Daily Necessities: Common everyday items that fall under this category are hoses like toothpaste tubes, toys, plastic covers, and disposable gloves. These products play important roles in maintaining hygiene and convenience in our daily lives.

Industrial Field: Within the industrial sector, plastic is widely used as an insulation layer for wires and cables, as well as in agricultural films for purposes such as insulation and moisture retention. These applications demonstrate the versatility and practicality of plastic in industrial settings.
