- EC Number
- 620-523-3
- Chemical Name
- Poly-tert-butylphenoldisulfide
Flyadd® VA7 is a sulfur donor for natural and synthetic rubbers. This product can be used in EV and sime-EV type cure systems as a complete or partial replacement for sulfur, thiuram, and DTDM sulfur donors. It can be used with most typical rubber accelerators and sulfur and is especially good for curing rubber that contains chlorine, such as chlorobutyl and polychloroprene. When used as a partial replacement for sulfur, it tends to improve the dispersion of other additives in the rubber.
