Durable PE Rod from China Suppliers & Factory for Impact Strength in Industrial Applications

PE (polyethylene) rod, a premium thermoplastic material, is available in both high-density polyethylene (HDPE) and ultra-high molecular weight polyethylene (UHMWPE). Characterized by its high crystallinity and non-polar structure, this material offers exceptional corrosion resistance and is safe for various applications as it is non-toxic and harmless. The rod has a milky white appearance and a translucent cross-section, making it not only functional but also visually appealing. With the ability to perform in a wide temperature range from -70℃ to 100℃, it is ideal for complex environments. Our PE rods are perfect for diverse industries, including industrial, medical, and agricultural fields. As a trusted China supplier and factory, we ensure high-quality products that meet your needs

    Product Details

    Parameter of PE Rod

    Parameters Description
    Material High Density Polyethylene (HDPE) or Ultra High Molecular Weight Polyethylene (UHMWPE)
    Density 0.93-0.97 g/cm³ (HDPE); 0.93-0.97 g/cm³ (UHMWPE)
    Temperature Resistance Range -70℃~100℃
    Tensile Strength ≥20 MPa (HDPE); UHMWPE is more impact resistant
    Water Absorption <0.01% (Very Low)
    Chemical Resistance Acid and alkali resistance (not resistant to strong oxidizing acids such as concentrated nitric acid)
    Electrical Insulation Excellent, suitable for electrical equipment
    Color Milk white, other colors are available
    Standard Size Diameter range: 5mm~500mm; length can be customized

    Production Process of PE Rod

    1. Raw material preparation
    Select HDPE or UHMWPE pellets, drying treatment (temperature ≤ 80 ℃) to remove moisture.
    2. Extrusion molding
    Heating and plasticizing by twin-screw extruder, temperature is controlled in stages (160℃→220℃), and the mold is designed to ensure smooth flow path.
    3. Cooling and sizing
    Vacuum sizing tank to control the outer diameter, spray water cooling (water temperature 10~25℃) to reduce internal stress.
    4. Traction cutting
    The traction speed is synchronized with the extrusion, and the precision cutting equipment ensures that the length error is ≤1mm.
    5. Inspection and Packaging
    On-line testing of wall thickness, outer diameter, sampling for hydrostatic test (such as GB/T 6111 standard).

    Advantages of PE Rod

    1. Chemical stability
    Resistant to most acid and alkali corrosion (except strong oxidizers), suitable for chemical industry, sewage treatment and other environments.
    2. Physical Properties
    Abrasion resistance 4 times that of steel, high impact resistance (elongation at break >500%), excellent low temperature toughness.
    3. Light weight and safety
    Low density, convenient handling; non-toxic and harmless, in line with food grade and medical standards.
    4. Flexible processing
    Support electric welding, heat welding and other connection methods, customized size and color.

    Application of PE Rod

    1. Industrial manufacturing
    • Seals, sliding profiles: used for wear-resistant parts of mechanical equipment (e.g. cutting plates, bearings).
    • Chemical piping: corrosion-resistant transportation piping (gas, sewage).
    2. Medical field
    • Medical appliances: Surgical instrument parts, catheters (e.g. PE vascular cannulae).
    3. Agriculture and Municipal
    • Irrigation system: weather-resistant, suitable for agricultural drip irrigation.
    • Water supply and drainage pipes: smooth inner wall, high circulation efficiency.
    4. Electricity & Communication
    • Insulation material: Bakelite board, cable protection sleeve.

    In Summary

    With its corrosion resistance, high abrasion resistance, light weight and other characteristics, PE rod has become an ideal material in many fields. The production process focuses on precision control, and the product parameters can be flexibly adapted to the demand, which is widely used in industrial, medical, agricultural and other fields.

    Frequently Asked Questions (FAQ)

    What raw materials are used to manufacture PE rods?

    PE rods are primarily made from High Density Polyethylene (HDPE) or Ultra High Molecular Weight Polyethylene (UHMWPE), depending on the specific mechanical and wear-resistance requirements.

    What is the temperature resistance range of a PE rod?

    PE rods feature a working temperature resistance range of -70℃ to 100℃, offering exceptional low-temperature toughness and stable performance in cold environments.

    How chemically resistant are PE rods?

    PE rods offer excellent acid and alkali resistance, making them ideal for chemical transportation and sewage systems. However, they are not recommended for exposure to strong oxidizing acids like concentrated nitric acid.

    Are PE rods safe for medical and food contact applications?

    Yes, PE rods are non-toxic, harmless, and comply with food-grade and medical standards. They are widely used in medical appliances, catheters, and food processing equipment.

    What custom sizes are available for PE rods?

    Standard diameters range from 5mm to 500mm. The length can be fully customized, and length errors are kept within ≤1mm thanks to precision cutting during production.

    Can PE rods be welded or easily processed?

    Yes, PE rods support flexible processing techniques including electric welding and heat welding, allowing them to be easily joined and customized to fit specific structural needs.
