Properties of polyethylene: key characteristics and comparison of types
Polyethylene is a versatile synthetic polymer that plays a leading role in packaging production, as well as in the manufacture of household and industrial goods. Its popularity is due to its unique physical, chemical, and mechanical properties. In this article, we will explore the main properties of polyethylene and compare the three most common types: LDPE, HDPE, and LLDPE.
Physical Properties of Polyethylene
- Low density — depending on the type, from 0.91 to 0.97 g/cm³;
- Flexibility and elasticity — especially true for LDPE and LLDPE;
- High tensile strength — particularly for HDPE and LLDPE;
- Wear resistance — withstands mechanical stress well;
- Temperature resistance — operates from -60°C to +80°C (depending on the type).
Chemical Properties of Polyethylene
- Inertness — does not react with water, acids, or alkalis;
- Resistance to organic solvents;
- UV resistance (with stabilizers);
- Eco-friendliness — recyclable and suitable for multiple reuses.
Mechanical Properties of Polyethylene
- High impact resistance;
- Low coefficient of friction;
- Good weldability — easy to shape when heated.
Main Types of Polyethylene
- LDPE (Low-Density Polyethylene) — flexible, soft, used for lightweight bags and films;
- HDPE (High-Density Polyethylene) — rigid and strong, used for durable bags, containers, and pipes;
- LLDPE (Linear Low-Density Polyethylene) — combines flexibility and strength, ideal for stretch films and heavy-duty sacks.
Comparison Table: LDPE vs. HDPE vs. LLDPE
To help you choose the right type of polyethylene, we’ve summarized the main characteristics in the table below:
Property | LDPE | HDPE | LLDPE |
---|---|---|---|
Density | 0.91–0.925 g/cm³ | 0.941–0.965 g/cm³ | 0.915–0.940 g/cm³ |
Flexibility | High | Low | High |
Tensile strength | Medium | High | High |
Puncture resistance | Low | High | High |
Chemical resistance | High | Very high | High |
Temperature range | -50°C to +80°C | -60°C to +80°C | -40°C to +70°C |
Typical uses | Films, food packaging | Pipes, containers, strong bags | Stretch film, heavy-duty sacks |
Why Choose Polyethylene?
Polyethylene offers a combination of low production cost, excellent physical and chemical properties, and recyclability. That’s why it is the ideal material for packaging, product transportation, pipe systems, and a wide range of consumer goods.
