CASHEW NUT SHELL LIQUID

CNSL constitutes 20-25% of cashew nut shells and is extracted via hot oil pressing, solvent methods, or supercritical CO2 processes to yield raw or distilled forms.​
Purification removes impurities like sulfur compounds, resulting in pale-colored distilled CNSL with key components: cardanol (60-65%), cardol (15-20%), and anacardic acid.​

CNSL exhibits high viscosity, low volatility, and excellent adhesion, polymerizing into flexible, heat-resistant resins under acidic or basic conditions.​
It offers superior chemical resistance, flexibility in cured films, and compatibility with synthetic resins, outperforming phenol in many eco-friendly formulations.​

In surface coatings, CNSL-based phenolic resins produce anti-corrosive paints, laminates, and foundry core oils for automotive and construction sectors.​
Rubber compounding uses it as a plasticizer and softener in tires, belts, and footwear; friction materials leverage it for brake linings and clutch plates.​

Epoxy curing agents from CNSL polyamines enhance adhesives, laminates, and composites; it also serves in biofuels, pesticides, and pharmaceutical intermediates.​
Textile processing employs CNSL as a dye fixative, while water treatment benefits from its coagulant properties for purification.​

For cashew processors like your shell cake operations, CNSL extraction maximizes by-product value, generating revenue from 85-90% recovery rates and export markets.​
Highlighting CNSL on your website boosts PR, attracts industrial buyers, and aligns with sustainable trends in green chemistry and renewable materials.
