Understanding Polyethylene Grades

Linear Polyethylene

Linear polyethylene is the norm in manufacturing plastic tanks. This material is renowned for its durability and resistance to environmental stress cracks. Here are some of its distinctive features:

  • Weldable, allowing for unique or site-specific fittings
  • A maximum operating temperature of 140°

Crosslinked Polyethylene

Crosslinked polyethylene offers a higher strength level than its linear counterpart, thanks to the introduction of crosslinked molecules during moulding. This modification results in:

  • Increased environmental stress crack resistance
  • A higher maximum operating temperature of 150°

Appearance and Benefits

Polyethylene water tanks come in various shapes, colours and sizes, making installation and transportation easy. They also offer a wide range of benefits, including cost-effectiveness, water quality maintenance and ease of installation, making them suitable for underground installations as well.CTA: Ready to invest in a polyethylene water tank that promises quality and durability?
