Core Advantages of High-Density Polyethylene (HDPE)

High Strength and Rigidity: The molecular chains are linear and tightly packed, with a crystallinity of 80%–95%, giving it tensile strength, impact resistance, and wear resistance significantly superior to low-density polyethylene (LDPE).

Excellent Chemical Stability: Resistant to corrosion by acids, bases, salts, and various organic solvents at room temperature, insoluble in general solvents, suitable for corrosive environments in chemical and food industries.

Good Heat and Cold Resistance: Typical use temperature range is -40°C to 100°C, can withstand 125°C–135°C for a short period, while maintaining impact resistance at low temperatures.

Non-toxic and Tasteless, Compliant with Food Contact Standards: Widely used in food packaging, beverage bottles, seasoning containers, etc.

Low Water Absorption and Excellent Moisture Resistance: Extremely low water absorption, low water vapor permeability (e.g., HDPE film ≤1.0×10⁻¹³), suitable for moisture-proof packaging or barrier materials.

Excellent Electrical Insulation Performance: Low dielectric constant and loss, suitable for wire and cable sheaths, electronic component packaging, etc.

Easy Processing and Recyclable: Can be molded through injection molding, blow molding, extrusion, etc.; supports chemical recycling with a recovery rate of over 70%, and the carbon footprint of green HDPE is 80% lower than fossil-based materials.
