What physical properties does Veenox 1010 (CAS 6683-19-8) have?
Veenox 1010 is a white, free-flowing powder with a melting range of 110–125 °C.
It has a molecular formula of C₂₅H₄₂O₃ (for the active portion as per Vinati) and a molecular weight of around 1178 g/mol. Its flash point is very high (297 °C), which contributes to its thermal stability in high-temperature applications
How much Veenox 1010 should be used (dosage) in formulations?
The typical dosage of Veenox 1010 (CAS 6683‑19‑8) ranges from 500 to 1,000 ppm, depending on the polymer and processing conditions. Using the correct amount ensures optimal antioxidant protection without affecting physical properties. Higher dosages may be required for long-term stability in demanding applications.
Is Veenox 1010 (CAS 6683-19-8) compatible with other stabilizers?
Yes it can be used in combination with secondary antioxidants such as phosphites / thioethers to create a synergistic effect. Because of its low volatility and high molecular weight, Veenox 1010 helps improve long-term performance when paired with other stabilizers. Its non-discoloring nature means it doesn’t negatively affect the aesthetic of the final product when used with other additives.
How does Veenox 1010 improve thermal stability in plastics?
Veenox 1010 (CAS 6683‑19‑8) acts as a sterically hindered phenolic antioxidant, neutralizing free radicals generated during high-temperature processing. This prevents polymer chain degradation, discoloration, and loss of mechanical properties. It is particularly effective in high-heat applications like extrusion and injection molding.
Can Veenox 1010 (6683‑19‑8) be used in food-contact polymers?
Yes, Veenox 1010 (CAS 6683‑19‑8) can be used in certain food-contact plastics such as polyethylene films and packaging materials. Its high molecular weight and low volatility minimize migration into food. Regulatory compliance should always be verified before use in food-contact applications.
Is VEENOX 1010 compatible with other antioxidants?
Yes. VEENOX 1010 can be blended with phosphite antioxidants, thioesters, UV absorbers, and HALS stabilizers to create synergistic stabilization packages for polymers.
