The high-boiling residue obtained after vacuum distillation of Cardanol from Cashew Nut Shell Liquid (CNSL) — a thick, dark, highly viscous phenolic material valued wherever high-viscosity phenolic raw materials are required.
Product Overview
Residol is the high-boiling residue obtained after the vacuum distillation of Cardanol from Cashew Nut Shell Liquid (CNSL). It is a thick, dark brown to black, highly viscous liquid formed primarily due to the polymerization of the non-cardanol components present in CNSL.
Its unique characteristics make it a valuable raw material for various industrial applications, particularly where high-viscosity phenolic materials are required — from friction materials and phenolic resins to industrial binders, adhesives, and low-cost industrial fuel blending.
Key Characteristics
A robust, high-viscosity phenolic material with predictable handling behaviour — backed by documentation-driven quality on every shipment.
Designed For
Residol serves industries that depend on high-viscosity phenolic materials — from friction materials and phenolic resins to binders, adhesives, and industrial fuel blending.
