Cashew Nut Shell Liquid(CNSL) is a reddish brown viscous liquid extracted from a soft honeycomb structure inside the cashew nutshell. The typical composition of technical CNSL is approximately 52% Cardanol,10% cardol, 30% polymeric material, with the remainder being made up of other substances.CNSL can be decarboxylated and distilled to yield high purity cardanol, a highly desirable alkylphenolic compounds.
The unique properties of Cashew Nut Shell Liquid are used to manufacture a wide range of products for industrial, chemical and end-user applications which can be used as an organic substitute for the higher cost phenol based products while at the same time introducing unique features and advantages over some traditional chemistries which find the application in resin, coating, friction, rubber and other industries.
Properties of Cashew Nut Shell Liquid （CNSL):
- It is a Low-cost Phenol
- Has great properties for chemical modification and polymerization
- Helps in manufacturing high-performance polymers
- Its advantages over phenolics have many applications like flexibility, high impact resistance, heat degeneracy, etc
- Liquid resin is used in the automobile industry as the brake lining
- Helps in preparation of Phenol-Formaldehyde Resin and Cashew Friction Dust (CFD)
Applications of CNSL:
Epoxy Resins
Friction Linings
Fuel industry
Laminating Resin
Surface coating and paints
Surfactants
