On the flip side, High-density polyethylene is tougher, harder, and provides greater impact strength and good resistance to heat, chemicals, and moisture. Thus, HDPE is classified as engineering plastic materials, and they apply in the fabrication of automotive parts and pipe systems.
Comparison between LDPE and HDPE
- Flexibility: LDPE is more flexible than HDPE, making it suitable for applications that require bendable materials.
- Strength and Rigidity: HDPE is stronger and more rigid than LDPE, making it ideal for applications that require high strength and stiffness.
- Chemical Resistance: Both LDPE and HDPE have excellent chemical resistance, but HDPE is generally more resistant to a wider range of chemicals.
- Transparency: LDPE is naturally translucent, while HDPE is more opaque.
- Durability: Both materials are durable, but HDPE is more resistant to impact and wear.
- Temperature Resistance: HDPE can withstand a wider range of temperatures compared to LDPE.
