Impact, and wear resistant. Flexible, can have very high elongation before breaking. Generally good chemical resistance.
  • Food Contact Acceptable
  • Processability, Good
  • Copolymer
  • ESCR, High (Stress Crack Resist.)
  • Antioxidant
  • Density, Low
  • Density, High
  • Impact Resistance, Good
  • Toughness, Good
Disadvantages of High Density Polyethylene
Sensitive to thick sections in your part. It may have voids, bubbles or sink. Poor dimensional accuracy. Low mechanical and thermal properties. Price is low to very low.
  • High thermal expansion
  • Poor weathering resistance
  • Subject to stress cracking
  • Difficult to bond
  • Flammable
  • Poor temperature capability
  • Low strength/stiffness
Background of High Density Polyethylene
After its experimental preparation in the 1930s the application in high frequency radar cables during World War II gave impetus to its commercial production. Today Polyethylene (PE) is one of the most widely used plastics with production in the billions of pounds each year.
