Product Application
  • ProFlex 8 is highly polar and readily plasticizes nylon, other polyamides, shellac, cellulose acetate, and protein materials. It is outstanding for making compounds resis- tant to oils, solvents, and greases.
  • Because of its low solubility in petroleum hydrocarbons, ProFlex 8 may be used to produce grease and oil-resistant coatings and adhesives. Nitrocellulose lacquers resistant
  • to grease and aliphatic hydrocarbons may be made by combining ProFlex 8 with ProFlex MH (a sulfonamide- formaldehyde resin).
  • In nylon and other polyamides, ProFlex 8 aids processing by lowering the melting point and improving low temperature flexibility.
  • Cellulose acetate plasticized with ProFlex 8 has a brilliance an polish not obtained with other plasticizers, and sheets and films obtain high tensile strength, elongation and flexibility.
  • Polyvinyl acetate adhesives plasticized with ProFlex 8 show exceptional grease resistance and have a quick tack and adhesion for joining difficult surfaces such as rubber to metal.
  • ProFlex 8 is an excellent dye solvent and pigment disper-sant.
