ExxonMobil HD 6605.70 HDPE Resin

Physical Properties

• Density: ASTM D4883 sets density at 0.948 g/cc (0.0342 lb/in³), defining mass per unit volume under standard test conditions.
• ESCR: ASTM D1693 Cond. B (10%) shows 20-hour resistance, indicating moderate tolerance to environmental stress cracking.
• Melt Flow: ASTM D1238 measures 5.0 g/10 min at 190°C/2.16 kg, showing adequate flowability for manufacturing processes.

Polymer Properties:

• Base Material: High – Density Polyethylene (HDPE).
• Modification Features：
  
  • Hexane copolymer structure offers excellent environmental stress crack resistance.
  • Maintains a favorable stiffness – toughness balance.
  • Resists gas fade effectively.

Applications:

1. Packaging Industry
   • Food Packaging: HDPE is widely used in the production of containers for milk, water, juices, and other food products due to its non-toxic properties and high resistance to UV degradation.
   • Bottles and Containers: The resin’s high strength and low permeability make it ideal for making durable, lightweight bottles.
     • Data Point: HDPE bottles are known to reduce the weight of packaging by up to 30% compared to glass bottles, leading to reduced transportation costs.
2. Consumer Goods
   • Toys and Household Items: HDPE’s resistance to impact and environmental stress makes it ideal for durable products like toys, containers, and outdoor furniture.
     • Data Point: HDPE’s tensile strength ranges from 3,000 to 5,000 psi, ensuring products withstand rough usage.
3. Automotive Components
   • Fuel Tanks and Engine Components: Due to its high chemical resistance, HDPE 6605.70 is used in automotive fuel tanks and engine parts that need to withstand exposure to fuels, oils, and other aggressive chemicals.
   • Interior Components: Used for non-structural components such as dashboard panels, trim pieces, and interior linings.
4. Agricultural and Industrial Applications
   • Irrigation Systems: HDPE is used to produce pipes and tubing for irrigation systems due to its durability and resistance to UV degradation.
     • Data Point: HDPE pipes can have a service life of over 50 years, which is about twice as long as traditional PVC pipes.
   • Chemical Tanks: Due to its excellent resistance to a wide range of chemicals, it is widely used for manufacturing storage tanks for hazardous materials.
5. Construction Industry
   • Geo-membranes: Used as a liner for landfills, reservoirs, and ponds due to its impermeability and strength.
   • Pipes and Fittings: HDPE 6605.70 is used to create strong and corrosion-resistant pipes for underground systems, often used in municipal water systems, sewage, and stormwater management.
6. Healthcare
   • Medical Containers: Its non-toxic, sterile, and high-resistance properties make it suitable for medical packaging, including syringes, bottles, and medical trays.
