Cat Loi Cashew Oil Production & Export JSC

Cashew phenol popularly know as Cardanol or Card-Phenol manufactured from cashew nut shell liquid (CNSL). It’s a monohydroxyl phenol having a long hydrocarbon chain (C15H27) in a meta position.

The components of commercial Cardanol different in the degree of unsaturation Of the side chain but for the practical purposes it can be represented by the following formula:

C6H4(OH)-(CH2)7-CH=CH-CH2-CH=CH(CH2)2 -CH3

Property:

    • A light pale Brown/yellow liquid manufactured from Cashew Nut Shell Liquid
    • Also know as cashew phenol
    • The unique molecular structure of Cardanol, especially unsaturation of long Hydrocarbon said chain, makes the cross linking easy on Polymerization
    • Besides the side chain imparting hydrophobic nature to the polymer, its coating is water repellent and weather resistant.

    • Cardanol based resins posses an outstanding resistance to softening action of mineral oil and high resistance to acids alkalies, antimicrobial property termite and insect resistance etc.
    • Contributes to improved flexibility, good drying after banking, high electric insulation properties and thermal stability.

    • Amenability to chemical modification to effect desirable changes so as to get specific properties for making tailor-made polymers of high value, thus the structural changes could be effected at the hydroxyl group, on the aromatic ring and on the side chain.
    • These properties make Cardanol an effective substitute for the petroleum-based phenol.

  • Cardanol polysulfide (CPS) has been used as a vulcanizing agent for natural rubber. Coordination bond linkage in cardanol-aldehyde condensation polymers improved its physicomechanical properties. This positively influences the anticorrosive properties and stability of the polymeric compound at high temperature. The blend of cardanol-based novolac-type phenolic resins, with commercial epoxy or isocynate monomers produces thermoset polymers . The conversion of CNSL-based cardols (6-alkenylresorcinols) into lasiodiplodin, a naturally occurring 12-membered orsellinic acid type macrolide, exhibits plant growth-regulating and antileukemic properties.

Specifications:

  • Density @ 300C :9275 – 0.9350
  • Viscosity @ 250C (cps) : 40 – 60
  • Iodine value : 210 -280
  • Ash content : Negotiable
  • Volatiles losses: 5 – 2%
  • Acid value : 2 – 5%.

The products obtained from CARDANOL have many advantages over these manufactured from other substituted phenols. It is therefore widely used in the manufacture of Nevolac & Resol Resins,  Oil Soluble Resins, Lamination, Surface coating & paints,  Electrical Insulating, Varnishes,  Brake lining, clutch facings,  Lacquers,  Pesticides, Rubber compounding,  Adhesives,  Wax substitutes,  Mineral oil additives,  Azo Dyes, etc.
