HDPE 5030SA, also referred to as HD5030SA, is a high-density polyethylene copolymer grade produced by Tabriz Petrochemical Company and specifically engineered for injection molding applications. As a copolymer, it incorporates a small proportion of comonomer into its polymer chain structure, a modification that improves environmental stress crack resistance while maintaining the stiffness and processability characteristic of high-density polyethylene.

This grade is supplied in natural granule or pellet form, ready for direct processing on standard injection molding equipment without additional compounding. Its balanced property profile — combining good stiffness, strong impact resistance, and reliable ESCR performance — makes it particularly well suited to applications where both dimensional stability and long-term durability matter.

HDPE 5030SA has become a preferred choice among cap and closure manufacturers for several practical reasons. Bottle caps demand a resin that can be molded quickly and consistently at high cycle rates while still delivering the stiffness needed for reliable torque retention and sealing performance over the product’s shelf life. HDPE 5030SA’s processability supports efficient, high-speed molding, while its stress crack resistance helps closures withstand the mechanical and chemical stresses of repeated use without premature failure.

Beyond caps and closures, manufacturers of injection molded containers, industrial components, and cable-related plastic parts choose this grade for its combination of surface finish quality, mechanical balance, and chemical resistance — properties that translate into fewer rejects and more consistent finished-part performance across large production runs.

For manufacturers operating high-volume injection molding lines, technical specifications are essential for ensuring stable processing, consistent product quality, and reliable production performance. Properties such as melt flow index, density, and mechanical strength directly influence mold filling, cycle time, dimensional stability, and the overall quality of the finished part. For this reason, industrial buyers typically review the complete technical data before approving a resin for production.

HDPE 5030SA supplied by Shobeir Shimi is accompanied by official Technical Data Sheets (TDS) and Certificates of Analysis (COA), allowing customers to verify every critical quality parameter. Typical values include:

• Melt Flow Index (190°C / 2.16 kg): 1.8 g/10 min (ASTM D-1238)
• Density: 0.948 g/cm³ (ASTM D-1505)
• Tensile Stress at Yield: 20 MPa (ASTM D-638)
• Elongation at Break: 1100% (ASTM D-638)
• Vicat Softening Point: 112°C (ASTM D-1525)
• Charpy Impact Strength: 15 kJ/m² (ASTM D-6110)
• Whiteness Index: 60 (ASTM E-313)
• Yellowness Index: −1 (ASTM E-313)

These balanced processing and mechanical properties make HDPE 5030SA particularly suitable for manufacturing caps and closures, plastic containers, and other precision injection-molded products. Its combination of controlled flow characteristics, high impact resistance, excellent surface finish, and good dimensional stability enables manufacturers to achieve consistent production efficiency and reliable end-product performance.
