Residol
residol - residue of cnsl distillation
During the distillation process of cashew nut shell liquid CNSL a thick viscous portion of the liquid is left behind. This residue is called RESIDOL. It is a highly polymerised cashew nut shell liquid. It is very good for the manufacture of bakelite, friction dust materials. They are very good in thermal properties.

PACKING RESIDOL
Residol flows easily only in hot conditions. In order to save fuel and cost hot residol is packed in MS Drums of net weight of 205kgs. Cooled residol is flowable in Indian conditions however, it requires little external heating when the temperature is below 20 degrees Celcius. Some customers to save heating cost prefer flowable residol which is manufactured by mixing residol with cnsl, to achieve the viscosity required by the customer.
