HDPE vs LLDPE vs LDPE - globalplasticsheeting.com

HDPE is also the most UV resistant-holding up to the harsh rays of the sun without needing UV additive packages. HDPE's strength comes from its tight cell structure that makes it very difficult for other molecules to pass through its structure on a microscopic level. When applications call for very large liners such as pond liners, HDPE is ...

Product & Technical FAQs from Advanced Drainage Systems

When specifying pipe, the crush strength is a term used for pipes that experience a brittle failure. In other words, the crush strength is the load at which the pipe physically breaks. This is not applicable to a viscoelastic material such as HDPE or an elastic material such as CMP since the material will deflect under load to the point of failure.

crush strength of upvc drain pipes

A HDPE pipe profile can actually deflect until the material is flattened due to reverse curvature. Therefore an analogous test to crush strength for HDPE pipes would be AASHTO s pipe flattening test which requires the pipe be deflected 20 with no signs of wall buckling cracking splitting or delamination at a specified pipe stiffness.
