Kindly let us know the difference between white PAF and grey PAF. Will it cause any difference in the application?

Does these two types of PAF are used for separate applications?

Apart from chemistry, what is the difference in Super grade, grade I and grade II based on its applications

Which PAF is used for which specific application.

Thanks and regards
