High-Density Polyethylene (HDPE) is a type of thermoplastic polymer made from petroleum, widely used for its strength, chemical resistance, and versatility. Here’s a breakdown:
1. Composition & Structure
• Monomer: Ethylene (C2H4)
• Polymerization: Usually produced via low-pressure polymerization using catalysts like Ziegler–Natta or chromium-based catalysts.
• Structure: Linear with minimal branching → allows molecules to pack closely → gives high density (≥ 0.94 g/cm3).
• Crystallinity: High (~60–80%), which makes it more rigid and strong than Low-Density Polyethylene (LDPE).
2. Key Properties
Property Typical Range Why it Matters
Density 0.94–0.97 g/cm3 High density = stronger, less permeable
Safety tips
- Avoid paying in advance, even for delivery
- Meet with the seller at a safe public place
- Inspect the item and ensure it's exactly what you want
- Make sure that the packed item is the one you've inspected
- Only pay if you're satisfied
