Chevron Phillips Marlex 9659 HDPE Resin

Physical Properties

• Density: In compliance with ASTM D1505, the density is 0.962 g/cc (0.0348 lb/in³), influencing its mechanical performance.
• Moisture Vapor Transmission: Measured by ASTM F1249, it is 0.100 cc – mm/m² – 24hr – atm, important for moisture – barrier applications.
• Melt Flow: Under Condition E per ASTM D1238, it is 1.0 g/10 min, related to its extrusion – processing behavior.

Polymer Properties:

• Base Material: High – Density Polyethylene (HDPE)
• Key Features:
  
  • Exhibits a paper – like film texture for a unique tactile and visual quality.
  • Has a high specific gravity, contributing to substantial mass and stability.
  • Offers low moisture vapor transmission, effectively preventing moisture ingress.
  • Provides good drawdown, enabling smooth stretching during film production.
  • Possesses high stiffness, ensuring shape retention and structural integrity.
  • Boasts high strength, enhancing durability and load – bearing capacity.
  • Shows high toughness, allowing it to withstand impacts and stresses.

Applications:

Marlex 9659 is a top-tier choice for various piping systems where durability, long-term reliability, and safety are non-negotiable.

• Water and Gas Pipes: Its PE 100 rating and outstanding hydrostatic strength make it the primary material for potable water pipes, gas distribution lines, and large-diameter water mains. 
• Industrial and Mining Pipes: The material’s robust chemical resistance and toughness are ideal for industrial process piping and mining slurry lines, where it must withstand abrasive materials and harsh chemicals.
• Underground Infrastructure: Its superior resistance to slow crack growth ensures a long service life for underground cable protection pipes and other buried applications where external stressors can be a factor.
• Corrugated Pipes: While primarily a pressure pipe resin, its excellent mechanical properties also make it suitable for manufacturing high-performance corrugated pipes for drainage and other non-pressure applications.
