Activated Carbon Powder
In Sri Lanka


Activated Carbon Powder manufactures in Sri Lanka


Activated carbon powder is manufactured in Sri Lanka, from pine wood & from other raw material or natural sources also. Pine wood based charcoals are soft, have a high degree of porosity, large surface area, and high purity, and therefore give better result compare with other carbon in Sri Lanka.


Washed activated carbon powder contains less iron, ash, acid & water soluble matter. It passes through i.p., b.p., & u.s.p. Parameters. So, it is quite suitable for bulk drug industries etc.
Unwashed activated carbon powder contains high iron, ash, acid & water soluble matter compared to washed activated carbon powder. So, it is quite suitable for dyes & intermediates industries, fine chemicals etc.
