Protecting rubber and plastics from aging, and preserving desired properties

  • Unrivalled track record of protecting rubber and plastics from thermal oxidation
  • Non-discolouring, non-pinking, with excellent colour purity
  • Protection from softening, hardening, brittleness and stickiness
  • Persistent as a process stabiliser, with low volatility
  • Extend the lifespan of your products and reduce service life costs

Our antioxidants provide a complete solution for oxidation. Wingstay antioxidants are highly effective polyphenol antioxidants which are suitable for natural and synthetic polymer-based articles like ABS, NBR, NR and XSBR, contributing a wide range of direct and indirect performance attributes to end-use products.

Synthomer’s Wingstay antioxidants also offer maximum protection against product degradation and discoloration during processing and storage. They help to extend the lifespan of rubber and plastic and reduce service costs by protecting them from oxygen degradation, while preserving the desired brittleness and stickiness required for a specific application.

Wingstay antioxidants can be used directly, or after being pre-dispersed or emulsified for latex. The additives fall into a number of categories, including gloves, foam, ABS, threads, adhesive and tapes.
