Akrochem Weston™ 618F Antioxidant
Categories: Other Engineering Material

Material Notes: Product Description: Weston™ 618F phosphate is a phosphite that is a highly effective color and molecular weight stabilizer fro polyolefins, polyesters, elastomers, styrenics, engineering thermoplastics, and adhesive formulations. It also contributes to the thermal and UV stability of these polymers. This product is available in a flake form.


  • Excellent color stability during processing, fabrication and end use
  • Polymer protection from degradation during processing
  • Reduced discoloration of polymers containing pigments such as TiO2
  • Reduced discoloration of polymers that are stabilized with a sulfur-containing, nickel-organic complex and are processed at high temperatures
  • Synergism when used with light stabilizers such as benzophenones and benzotriazoles
