Production process of pe rod
Select HDPE or UHMWPE pellets, drying treatment (temperature ≤ 80 ℃) to remove moisture.
Heating and plasticizing by twin-screw extruder, temperature is controlled in stages (160℃→220℃), and the mold is designed to ensure smooth flow path.
Vacuum sizing tank to control the outer diameter, spray water cooling (water temperature 10~25℃) to reduce internal stress.
The traction speed is synchronized with the extrusion, and the precision cutting equipment ensures that the length error is ≤1mm.
On-line testing of wall thickness, outer diameter, sampling for hydrostatic test (such as GB/T 6111 standard).
Advantages of pe rod
Resistant to most acid and alkali corrosion (except strong oxidizers), suitable for chemical industry, sewage treatment and other environments.
Abrasion resistance 4 times that of steel, high impact resistance (elongation at break >500%), excellent low temperature toughness.
Low density, convenient handling; non-toxic and harmless, in line with food grade and medical standards.
Support electric welding, heat welding and other connection methods, customized size and color.
Application of pe rod
- Seals, sliding profiles: used for wear-resistant parts of mechanical equipment (e.g. cutting plates, bearings).
- Chemical piping: corrosion-resistant transportation piping (gas, sewage).
- Medical appliances: Surgical instrument parts, catheters (e.g. PE vascular cannulae).
- Irrigation system: weather-resistant, suitable for agricultural drip irrigation.
- Water supply and drainage pipes: smooth inner wall, high circulation efficiency.
- Insulation material: Bakelite board, cable protection sleeve.
In Summary
HDPE (High Density Polyethylene) rods offer good tensile strength and chemical resistance, while UHMWPE (Ultra High Molecular Weight Polyethylene) rods provide significantly higher impact resistance and superior wear resistance, making them ideal for heavy-duty sliding and mechanical parts.
Standard PE rods can operate reliably within a temperature resistance range of -70℃ to 100℃, retaining excellent toughness even in extremely cold environments.
Yes, PE rods feature outstanding chemical stability and resist most acids and alkalis. However, they are not resistant to strong oxidizing acids such as concentrated nitric acid.
Yes, PE rods are non-toxic, odorless, and harmless. They comply with strict food safety and medical standards, making them suitable for food processing equipment and medical appliances.
The standard diameter range for PE rods is from 5mm to 500mm. The length can be custom-cut and tailored according to specific application requirements.
