Contex A series

Contex A series are water soluble ethylene oxide (EO)/propylene Oxide (PO) copolymer.

 Contex A series features a high viscosity index, low pour point, clean burn properties, inverse water solubility, low surface tension and low foam characteristics.

Contex A series can be used in a wide range of applications like:

  • Textile lubricants
    Contex A series, designed with special characteristics, results as an excellent choice as a base-stock in textile
    lubricants.
    Contex A series can lubricate polyester, polyamide, and polypropylene multifilament yarns, especially in
    texturizing operations and can also be used on woolens and cellulosics.
     
  • Metalworking fluids
    The inverse water solubility, good heat transfer properties and inherent lubricity characteristics results a perfect choice as a base to produce metal working fluids from aqueous solutions of Contex A series.
     
  • Gear/bearing and Calendar lubricants
    Contex A150 and A225 can be used as a gear and bearing lubricant, especially in high operating temperatures or in high loading environments.
     
  • Rubber lubricants
    Contex A150 and A225 can be used as a lubricant of rubber hoses and tires, especially in high operating temperatures or in high loading environments.
     
  • Polyethylene extrusion aid
    Contex A50 and Contex A100 can be used as an extrusion aid in the production of extruded polyethylene.
     
  • Mold release agents
    Contex A150 and A225 can be used as mold release agent of rubber hoses and tires, especially in high operating temperatures or in high loading environments.
     
  • Compressor lubricant
    Contex A series can also be used as compressor fluids when working with non-oxidizing gases such as ethylene, neon, helium, and argon

Contex A series offer the advantage of being biodegradable in neat products.

Contex A series are more soluble in cold water than in hot water, if inverse water solubility is required.
An aqueous solution of Contex A series will have a low surface tension and thus good wetting and penetration characteristics, while also exhibiting low foaming characteristics. In high temperature applications where decomposition can occur, Contex A series typically do not leave black carbon or sticky residues. The decomposition products are volatile or are solubilized into the base-stock. Oxidation stability can be improved by the inclusion of anti-oxidants.
