Cashew Nut Shell Liquid (CNSL) is a high-value industrial byproduct extracted from the shell of cashew nuts. With growing demand in global manufacturing, CNSL plays a vital role in automotive, chemical, and construction industries.
π SVC Cashew is a trusted supplier of bulk CNSL from Vietnam, offering both crude and refined forms with reliable capacity and export documentation.
π§ͺ What is CNSL?
CNSL is a dark brown viscous liquid containing natural phenolic compounds:
- Anacardic Acid (60β70%)
- Cardol (15β20%)
- Cardanol (5β10%)
- Trace methyl cardol and other alkenyl phenols
Its molecular structure provides friction-reducing, polymerizing, and anti-corrosive properties.
βοΈ Extraction Process
SVC uses two industrial extraction methods:
π₯ Hot Oil Bath β Heats shells at ~190β200Β°C to release CNSL
π§ Mechanical Expression β Crushes roasted shells to extract CNSL
π§Ή Optional refinement or filtration available as per request
