In the raw material step, we do chemical composition testing in every batch sampling, also we test the hydrogen content of the raw 

materials, we onlyput into production after the raw materials are tested and qualitied. In production, we performsampling tests on 

each different work steps,  include Physical performance, chemical composition, dimension, color, gloss, film thickness…etc.
