Applications

Vac-11 (3,9-dicyclohex-3-enyl-2,4,8,10-tetraoxaspiro(5,5)undecane) is a cyclic acetal (pentaerythritol-bis-tetrahydrobenzaldehyde acetal).

Product Overview: Nonstaining antiozonant, excellent dynamic protection and excellent antioxidant protection. Protect vulcanizates where color and design play a major role, perfectly suit for light-color and color rubber products, will not change products’ color.

• VAC-11 I non-staining property makes it possible to be used in light-color or color products , especially high-level rubber products, such as
  • Profiles, hose, seal, cable, auto parts
  • IIR tube, cycle tire, white sidewall, color tire
  • Sneakers and other leisure products
• (3,9-dicyclohex-3-enyl-2,4,8,10-tetraoxaspiro (5,5)undecane) VAC-11is highly effective in CR, C IIR and BIIR, even without wax.
• Also used in NR, SBR or blended rubber, and IIR/CR (95/5) blended rubber or inner rubber.
• No protection from heat oxidation, flexing resistance, or rubber poisons, need to synergies with other anti-aging agents.
