Additive Choices

There are many material components you can discuss with your Goodyear Rubber representative that will match your rubber application needs including:

  • Fillers help performance and provide durability. Several types are available including carbon black reinforcing, hard clay semi-reinforcers and non-reinforcers such as calcium carbonate.
  • Internal lubricants get mixed into the compound to keep it from sticking to equipment and to lower heat build-up.
  • Protectants include metal deactivators, flame retardants and antioxidants that retard deterioration caused by oxygen contact, waxes, and antiozonants that slow deterioration because of contact with ozone.
  • Colorants, remove cross-contamination of dry pigments, brighten color consistency, boost product quality and decrease processing costs.
  • Vulcanizing agents supply the chemical process that converts polymers and rubber into a more durable, rubber-elastic material end product.
  • Sulfur, sulfur donors and other chemicals that encourage cross-linking are curatives.
  • Blowing agents generate gas by a chemical or thermal action if added to a rubber compound when manufacturing sponge or cell products.
  • Bonding agents assist with holding dissimilar materials together in the complete rubber product
  • Tackifiers give a short and long-term tack in the compound causing two layers to bond together with light pressure. The tacky compounds often do not stick to other surfaces.
  • Plasticizers improve the flow of rubber during processing.

Your application will determine the additive you need.
