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.
👉 SVC Cashew is a trusted supplier of bulk CNSL from Vietnam, offering both crude and refined forms with reliable capacity and export documentation.
🧪 What is CNSL?
CNSL is a dark brown viscous liquid containing natural phenolic compounds:
- Anacardic Acid (60–70%)
- Cardol (15–20%)
- Cardanol (5–10%)
- Trace methyl cardol and other alkenyl phenols
Its molecular structure provides friction-reducing, polymerizing, and anti-corrosive properties.
⚙️ Extraction Process
SVC uses two industrial extraction methods:
🔥 Hot Oil Bath – Heats shells at ~190–200°C to release CNSL
🔧 Mechanical Expression – Crushes roasted shells to extract CNSL
🧹 Optional refinement or filtration available as per request
