Topanol™ Antioxidants

Topanol Antioxidants, are high molecular weight hindered phenolic antioxidants, which are available in two forms. 

  • Topanol™ CA (for non-plastics applications)
  • Topanol™ CA-SF (for plastics applications) 

They are primarily in polymer systems that are sensitive to thermal and oxidative degradation due to free radical and peroxide formation. degradation at high processing temperatures and will extend the service life of polymers that are used at elevated temperatures.

The original grade of Topanol CA-SF, a registered trademark used under license by Imperial Chemical Industries, was developed over 40 years ago and has gained an excellent reputation in the polymer industry. It is highly efficient compared to other hindered phenols. It has low volatility, does not stain, making it is useful in polymers intended for a very wide range of end uses. Its high efficiency can be enhanced by using it with secondary antioxidants such as phosphites and thioesters, which produce synergistic effects, leading to very effective and economical formulations.

Topanol CA-SF is used at very low levels in the following applications:

  • PVC plasticizers and compounding, primarily for stabilizing plasticizers in automotive wire and cable applications
  • ABS, MBS, and SBR styrenic polymers
  • Nylons and polyamides

Applications

Pill Coating

ZeMac E60 Copolymer optimizes glass fiber sizing chemistries for resins and composites by enhancing mechanical properties and increasing resistance to degradation. ZeMac E60 Copolymer is used as a coating additive for minerals & organic fillers are used in polymers. 

Microencapsulation

ZeMac Copolymers act as emulsion stabilizers and control mean particle size (MPS) & particle size distribution (PSD).
