HDPE Rod

15 - Aug - 2025

HDPE Rod is a thermoplastic engineering plastic rod made from high-density polyethylene (HDPE) through extrusion or compression molding. It boasts lightweight, impact-resistant, corrosion-resistant, non-toxic, odorless, and low water absorption, making it widely used in the food, chemical, machinery, shipbuilding, and electronics industries.

Main characteristics of HDPE Rod

1.Lightweight

Density: Only 0.94-0.96 g/cm³, lighter than water, making it easy to process and handle.

2.Excellent Chemical Resistance

Resistant to most acids, alkalis, salt solutions, and some organic solvents.

3.Excellent Impact Resistance

Remains stable, especially at low temperatures.

4.Extremely low water absorption

Resists deformation due to moisture, making it suitable for outdoor and humid environments.

5.Non-toxic, odorless, and food-grade.

Safe for direct food contact, FDA-compliant.

6.Excellent wear resistance and self-lubricating properties.

Suitable for low-friction and wear-resistant parts.

7.Excellent machinability.

Suitable for turning, milling, planing, drilling, welding, and other machining operations.
