Customer knew us from our official website, then asked us about the silica gel for oil color bleaching.
We suggest 2 sizes for customer test first, <0.3mm and <0.5mm, 500g each. That will be enough for the sample test. We also have more size for choice 0.3-0.7mm and 0.5-1mm. But <0.3mm and <0.5mm is the most suitable size considering the cost and oil recovery.
Sample is free for test. We also welcome more customers and friends come to contact us for more details. If you just have the needs on the fuel oil purification, it will be a good choice and try.
