Variable fade testing laboratory
Sample Size: 200mm thick rigid PU foam
Test temperature: 50 ℃
Add amount: 3% GGK-680/3% benzene well triazole UVA328
Measurement Unit: fade Index
Foam Density: 0.05 ~ 0.07 g / cm3
Test time: 72hrs
The experimental results
Add 3% GGK-680 PU rigid foam provides good light performance make changes in the value of yellowing foam fell 19.26. GGK-680 is a liquid product, the more well-triazole UVA328 powder state benzene products more convenient processing.
