Petrochemical clay SYKOL 220A

SYKOL 220A Bleaching Earth is made from natural Bentonite after a series of professional and especial processes, it shows the best condition for each kinds of oil purification. The proper acid value could remove the heavy metal and gums out of the oil, high activation degree could react with other substance in oil to reduce the refinery time and increase the efficiency.

According to the demand and actual production situation, we could customize good cost-effective products.




White or light gray


All kinds of industrial oils with dark oil or hard to clean. Like diesel fuel, lubricants, waste engine oil or used cooking oil etc.
