Abstract:
Cashew Nut Shell Liquid (CNSL) is a
versatile by-product of the cashew
industry. The nut has a shell of about 1/
8 inch thickness inside which is a soft
honey comb structure containing a dark
reddish brown viscous liquid. It is called
cashew nut shell liquid, which is the
pericap fluid of the cashew nut. It is often
considered as the better and cheaper
material for unsaturated phenols.
C.N.S.L. has innumerable applications
in polymer based industries such as
friction linings, paints and varnishes,
laminating resins, rubber compounding
resins, cashew cements, polyurethane
based polymers, surfactants, epoxy
resins, foundry chemicals and
intermediates for chemical industry. It
offers much scope and varied
opportunities for the development of
other tailor - made polymers.
