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.
