Topanol™ CA-SF

Technical Datasheet | Supplied by aurorium
Topanol™ CA-SF by aurorium is a high molecular weight hindered phenolic antioxidant. It has low volatility & does not stain, making it useful in polymers intended for a very wide range of end uses.
  • It is suitable for polymer systems that are sensitive to thermal and oxidative degradation due to free radical and peroxide formation.
  • It extends the service life of polymers that are used at elevated temperatures.
  • It has high efficiency compared to other hindered phenols, which can be enhanced by using it with secondary antioxidants such as phosphites & thioesters that produce synergistic effects, leading to very effective and economical formulations.
  • Topanol™ CA-SF is recommended for PVC plasticizers & compounding, primarily for stabilizing plasticizers in automotive wire and cable applications.
  • It is also used in nylons & polyamides (PA), acrylonitrile butadiene styrene (ABS), methacrylate butadiene styrene (MBS), and styrene-butadiene rubber (SBR) styrenic polymers.
