In fact, the warranty period of the sun board is the warranty of the yellowing index, depending on the UV (UV stabilizer) into the number of cases, under normal circumstances, 50μ UV yellowing index warranty for 10 years
10 years warranty is 10 years, light transmission rate decreased by 6%, yellow index change is less than 6. This is the plastic is not too much of the aging indicators. Means that after 10 years of good sunshine board physical mechanical properties decline is very little, basically will not affect the use of sex. Foreign pc sun panels are basically used for more than 20 years.
Good pc sunshine board is not like the above answer "is to provide", rely on equipment, technology, raw materials, testing means. Generally speaking, imported equipment uv co-extruded layer thickness is more uniform, the service life will be longer.
If you use the import of new materials, not adulterated any material, then, can guarantee a decade, but mixed with the material is not easy to say! Such as my experience, bought the city of the board did not take long yellow. Lock plate is not reliable! Khan this is a new material to do it? People in the day to see na!
