High-density linear polyethylene chemical storage tanks can’t stop cracking once it begins. Eventually the tank experiences catastrophic failure, “unzipping” itself. This is called notch sensitivity. Unfortunately, notches are unavoidable in rotomolded storage tanks.
You can eliminate notch sensitivity by using cross-linked polyethylene (XLPE) tanks, because molecular “bridges” or “crosslinks” prevent the material from unzipping.
Dramatic Test Proves the Rupture Resistance of Cross-Linked Polyethylene
To find out if the our crosslinked polyethylene tanks would hold up in the real world, we tested cross-linked and linear high-density polyethylene tanks. Rotomolded tanks from both materials were subjected to high-impact and over-pressurization tests. Even we were surprised by the results.
Download our comparative study to see for yourself how well the cross-linked polyethylene tanks performed under extreme conditions. This study reveals:
- The higher resistance of XLPE to rupture and catastrophic failure
- The ability of cross-linked polyethylene to resist crack propagation or unzipping
- The overall superior performance of XLPE material
- The added factors of safety that this material provides
