HDPE 5000S: Product Description and Properties

HDPE 5000S is a high molecular weight High-Density Polyethylene (HDPE) grade designed primarily for injection molding applications that require outstanding mechanical strength, rigidity, and resistance to chemicals. Produced using advanced Ziegler-Natta catalyst technology, HDPE 5000S combines superior toughness with excellent processability, making it one of the most widely used grades in the HDPE family for injection molding.

The polymer’s crystalline structure results in high stiffness, dimensional stability, and long-term durability. Due to its balanced mechanical and physical properties, HDPE 5000S is a preferred material for manufacturing heavy-duty molded components in both industrial and consumer applications.

Key Physical and Chemical Properties:

  • Melt Flow Index (MFI): 0.25 g/10 min (190°C/2.16 kg)

  • Density: 0.953 g/cm³

  • Tensile Strength at Yield: 28 MPa

  • Elongation at Break: >600%

  • Flexural Modulus: 1100 MPa

  • Environmental Stress Crack Resistance (ESCR): Excellent

  • Processing Method: Injection Molding

These characteristics enable HDPE 5000S to deliver exceptional impact strength and long-term reliability, even under harsh operating conditions.

Applications and Uses of HDPE 5000S

Thanks to its superior balance of mechanical strength, rigidity, and chemical resistance, HDPE 5000S has become a material of choice across a wide range of industries. It is widely used in injection molding processes to produce parts that demand dimensional accuracy, long life, and resistance to stress and impact.

Industrial Applications

In industrial settings, HDPE 5000S is used to manufacture robust products such as:

  • Plastic crates, pallets, and bins that can withstand repeated handling, stacking, and heavy loads.

  • Chemical containers and storage tanks due to its excellent resistance to acids, bases, and solvents.

  • Industrial packaging components, including lids, caps, and closures, that require a high degree of sealing integrity.

  • Battery cases, electrical housings, and automotive parts where chemical and impact resistance are critical.

Consumer and Household Applications

HDPE 5000S is also widely applied in consumer goods due to its non-toxic nature, smooth surface finish, and long-term durability:

  • Household containers, buckets, and trays designed for repeated use and easy cleaning.

  • Closures and caps for beverage and detergent bottles, providing leak-proof sealing performance.

  • Toys, furniture components, and appliances that require lightweight strength and aesthetic appeal.

Agricultural and Construction Applications

The excellent toughness of HDPE 5000S makes it suitable for outdoor and heavy-duty applications, including:

  • Agricultural crates, irrigation fittings, and tool housings, which demand UV stability and mechanical strength.

  • Construction materials such as formwork panels, protective casings, and pipe fittings that resist wear and corrosion.

In all these applications, HDPE 5000S delivers a balance of rigidity, chemical inertness, and processing ease, ensuring consistent performance and cost efficiency. Manufacturers appreciate its smooth flow characteristics, which allow for faster cycle times and precise mold filling without warping or defects.

Handling, Health, and Safety Information

When processing HDPE 5000S, it is essential to follow safety precautions at all times. The molten polymer may cause thermal burns if it comes into contact with the skin or eyes. Operators are advised to use protective gloves, safety glasses, and long-sleeved garments when handling the material in molten form.

Ensure proper ventilation during the melting and molding process to prevent the accumulation of fumes. Avoid dust buildup, as fine HDPE particles can create a static or explosion hazard. Maintain grounding and dust control systems at all times in processing and packaging areas.

Storage and Transportation

HDPE 5000S should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources. Extended exposure to ultraviolet (UV) rays can degrade the polymer, affecting its performance and color. Always keep the product in its original sealed packaging until ready for use to avoid contamination by dust, dirt, or moisture.

During transportation, handle the packaging with care to prevent mechanical damage. Protect the product from rain, high humidity, and extreme temperatures. HDPE materials are not classified as hazardous and can be transported safely under normal shipping conditions.
