Summary: Recycled-resin liner fails in 1-3 years under UV and media attack. Four field checks - look, smell, pull, weather - plus resin proof and batch testing are the reliable way to tell them apart.
The cheapest quote in a tender is often recycled resin. The rework cost of a failed liner dwarfs the material difference.
Four field checks
- Look: virgin membrane is glossy and uniform, cut edge shows no speckles;
The reliable route
- Ask for resin certificate (producer grade and batch);
All Hongyue liners are virgin resin with batch reports; sampling for your own lab is welcome.
