" />OIT measures the antioxidant content of HDPE geomembrane, indicating long-term UV and thermal stability.
Test Method
A small specimen is heated in oxygen in a DSC instrument. The time until oxidation starts is recorded. Higher OIT means better stabilization for long service life in exposed applications.
Why It Matters
This test reflects durability under outdoor UV exposure. We provide OIT and other test reports. See our product page or contact us.
