Short Description


Value added chemicals (specialty monomers and polymers) from cashew nut shell liquid that have wide ranging industrial and consumer applications

Abstract


TECHNOLOGY DESCRIPTION

A range of difunctional monomers (dihalides, diacids, diisocyanates, diamines, diacyl hydrazides, diphenols, dialdehydes etc.) and polymer additives are produced utilizing 3-pendadecyl phenol derived from cashew nut shell liquid (CNSL) using NCL’s technology. A host of high-performance polymers (polyimides, polyamides, polyesters, poly(amide-imide)s etc.) can be prepared using the difunctional monomers mentioned above.


MARKET POTENTIAL

• There is significant margins involved in producing value added chemicals from CNSL
• CNSL sells for about $500/ton whereas, Cardanol a CNSL constituent, when separated sells for over $3000/ton*
• India exports close to 10,000 tons of CNSL a year** - abundant availability of raw materials
• CNSL production capacity in India over 20,000 tons/year

VALUE/ ADVANTAGES

• High performance polymers produced from CNSL have improved processability characteristics
• Produced from low cost raw materials that are widely available in India
• Sustainable, renewable source


APPLICATIONS

• Thickeners in paints, cosmetics, oils, food and textiles
• Electrical insulating varnishes
• Enamels & adhesives
• Auto brake lining
• Substitute for linseed oil (in manufacturing foundry core oil, which is used as a binder)
• Cement hardening agent
• Used in lamination industry (for reduced brittleness and improved flexibility)
• Epoxy resins & rubber compounding resins


TECHNOLOGY STATUS

• Demonstrated at the lab scale
• On the lookout for potential partners for spin-off and licensing
• Patents granted: US 7,572,863, US 7,446,234
US 7,297,822, US 7,709,687
