Cashew Nut Shell Liquid (CNSL)
..............................................................................................................................................................................
Description
Cashew nut shell liquid is a co-product of the cashew nut industry and is sourced primarily from South America and Asia. It is a dark liquid comprised of different unsaturated alkenyl substituted phenols.
The Cashew nut shell liquid is the by-product of Cashew industry. The oil is being extracted from the cashew nut shell, which is a pericarp fluid of the cashew nut. This is purely a natural product and no chemical is added.
Application
The dual phenolic/alkenyl nature of CNSL makes it a potential natural raw material for the synthesis of water-resistant resins and polymers. Since natural variation in the chemical composition of plant oils can be a limiting factor in there wholesale use by the chemical industry CNSL has found only a small market as a component in the manufacture of friction dusts. To limit this variation, chemical modification of the alkenyl tail by reductive ozonolysis was thought to be an ideal strategy, to create a range of similar reactive monomers through cleavage of the double bonds into aldehydes. Furthermore, since the phenolic moiety, under both alkali and acid conditions, is highly reactive towards electrophiles such as aldehydes, no further cross-linking agent would be needed, as both functionalities would be inherent in every new molecule. The remaining alkyl aldehyde groups would increase the reactivity of the system towards cross-linking and impart a high degree of hydrophobicity.
The CNSL has got wide range of applicability for making raw materials for automobile Brake lining such as Liquid Resin, PF Resin and Cashew Friction Dust (CFD). The CNSL is also used for manufacture of paint and varnishes, Epoxy Resins and Oil soluble Resins, Surface active agent, Synthetic Rubber & Wax compounding and Foundry Resins and so on.

Vermiculite
..............................................................................................................................................................................
Description
Essentially vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance. It is found in various parts of the world, but currently the major mines are located in South Africa, China, Brazil, Zimbabwe, and the United States. The largest operating mines today are located in the Palabora region of North-Eastern Transvaal in South Africa, in the northwestern corners of China, and along the eastern Appalachian range in the United States (Virginia and South Carolina). The vermiculite ores from these mines are different forms of hydrated phlogopite or biotite mica which has the remarkable ability of being able to expand to many times its original volume when heated---a property known as exfoliation.
Application
As a filler in paints, plastics and printing ink. Manufacture of insulation bricks and castables. In chemical packing, As Oil spill absorbents, as lubricants in oil drilling. Core wash in foundry. Sealants in underground mines. In steel melting ladles and zinc baths. At the base of railway coaches for anti-corrosion and anti-Vibration.
