When the field latex is centrifuged,in addition to the concentrate containing most of the rubber, an equal fraction in volume containing very small proportion of rubber is obtained. This is known as skim latex.
But the centrifuging process has a normal efficiency of 75-90%. The 10-5% of the incoming rubber goes to the skim. As rubber is having some importance, it is necessary to recover the rubber in the skim latex.
