Description

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.

Features:

The texture is soft and tough, contrasting with the brittle nature of hard plastics that tend to crack.

It offers excellent low-temperature resistance, retaining its toughness even at -60 ℃, making it ideal for freezing conditions.

This material exhibits strong chemical stability, withstanding various chemicals including acids, alkalis, and salts, and remains insoluble in common solvents.

Furthermore, it boasts exceptional processability, enabling the production of films, pipes, toys, and other items using methods like blown film extrusion and injection molding.

Technical Parameters:

UV Resistance Good
Moldability Good
Chemical Resistance Excellent
Melting Point 105-115°C
Izod Impact Strength 10-30 J/m
Thermal Conductivity 0.33 W/m·K
Tensile Strength 10-17 MPa
Transparency Opaque
Flexural Modulus 0.2-0.4 GPa
Electrical Insulation Excellent

Applications:

When it comes to packaging field, the items with the highest proportion include food wrap, shopping bags, waterproof express bags, and inner layers of composite packaging bags.

In daily necessities, items such as hoses (like toothpaste tubes), toys, plastic covers, and disposable gloves are commonly used.

Within the industrial field, plastic is utilized as an insulation layer for wires and cables, as well as in agricultural film for purposes like insulation and moisture retention.
