HDPE-Taisox 8003H

Taisox 8003H, a specialized High-Density Polyethylene (HDPE) resin manufactured by Formosa Plastic Corporation, is expertly engineered for demanding pipe extrusion applications. This high-molecular-weight grade is renowned for its exceptional long-term hydrostatic strength, superior environmental stress crack resistance (ESCR), and robust toughness, making it the material of choice for reliable pressure pipes and industrial tubing.

Developed to meet the stringent requirements of infrastructure and industrial projects, Taisox 8003H ensures the production of pipes that exhibit excellent resistance to internal pressure, abrasive media, and harsh environmental conditions, guaranteeing extended service life and reduced maintenance.

Key Features & Benefits:

• Exceptional Long-Term Hydrostatic Strength: Taisox 8003H provides outstanding resistance to internal pressure over extended periods, making it ideal for high-performance pressure piping systems for water, gas, and industrial fluids.
• Superior Environmental Stress Crack Resistance (ESCR): Offers industry-leading resistance to stress cracking when exposed to aggressive chemicals, detergents, or demanding ground conditions, ensuring the integrity and longevity of buried or exposed pipes.
• High Molecular Weight: This characteristic contributes to the material’s excellent toughness, resistance to slow crack growth (SCG), and overall durability, crucial for demanding pipe applications.
• Good Chemical Resistance: Inherently resistant to a wide range of acids, bases, solvents, and other chemicals, ensuring the safe transport of various media.
• Excellent Abrasion Resistance: Performs well in applications involving the transport of abrasive slurries or where external wear is a concern.
• Consistent Extrudability: Designed for smooth and efficient processing through extrusion lines, allowing for stable pipe dimensions, consistent wall thickness, and high production rates.
• UV Stability: Can be formulated or compounded for enhanced UV resistance for outdoor applications, ensuring long-term performance under sunlight exposure.

Typical Applications:

Taisox 8003H is primarily recommended for critical extrusion applications requiring maximum durability and long-term performance:

• Pressure Pipes: For potable water supply, gas distribution, irrigation systems, and industrial fluid transfer.
• Ducts and Conduits: For cable protection in telecommunications and electrical infrastructure.
• Large Diameter Pipes: For sewerage, drainage, and other non-pressure applications where robust construction is needed.
• Heavy-Duty Sheets and Liners: For geomembranes, pond liners, and industrial containment.
• Mining Applications: Slurry pipelines and other demanding systems.

Typical Properties (Representative Values):

Please note that specific values may vary slightly depending on the exact production batch and testing conditions. Always refer to the official Technical Data Sheet (TDS) from Formosa Plastic Corporation for the most accurate and up-to-date information.

• Melt Flow Index (MFI) (190°C/2.16 kg): 0.2 – 0.4 g/10 min (ASTM D1238)
• Density: 0.954 – 0.958 g/cm³ (ASTM D1505)
• Tensile Strength @ Yield: 24 – 28 MPa (ASTM D638)
• Flexural Modulus: 900 – 1100 MPa (ASTM D790)
• Hardness, Shore D: 60 – 65 (ASTM D2240)
• VICAT Softening Point (A): ~125 – 128 °C (ASTM D1525)
• Environmental Stress Crack Resistance (ESCR) (F50, 10% IGEPAL, 50°C): >1000 hours (ASTM D1693, Condition B)

Processing Guidelines (Extrusion – General):

• Drying: Generally not required for HDPE, but if moisture is present due to improper storage, pre-drying at 80°C for 2-4 hours is recommended.
• Melt Temperature: 180 – 220 °C (optimize based on extruder type, die design, and desired output).
• Die Temperature: Maintain consistent temperature for uniform melt flow and pipe dimensions.
• Cooling: Adequate cooling is critical for maintaining pipe dimensions and mechanical properties.

Packaging & Storage:

Taisox 8003H is typically supplied in 25 kg bags or bulk containers. For optimal product quality and to prevent contamination or moisture absorption, store in a dry, cool, and well-ventilated area, away from direct sunlight and heat sources. Keep packaging sealed until ready for use.
