Acid Testing Data
Sour gas a week in the laboratory to simulate soft foam material after processing (such as: cutting foam) in a warehouse environment, suffered NOx gas attack caused foam yellowing phenomenon.
Description
Sour gas a week in the laboratory to simulate soft foam material after processing (such as: cutting foam) in a warehouse environment, suffered NOx gas attack caused foam yellowing phenomenon.
Acid gas experiments
Laboratory acidic environment
Sample Size: 200mm thick soft PU foam (TDI Base)
Add amount: 2%, 3% GGK-690
Measurement Unit: acid index
Foam density: 0.03 ~ 0.05 g / cm3
Test time: 168hrs
The experimental results
Add 3% GGK-690 PU rigid foam provides good light sour gas effectiveness; make foam yellow index fell to 6.27 and 5.35 YI, 13.5 better than the foam was not added.
