Curing Agents

Curing Agents

Suppliers of Peroxide, Magnesium Oxide & Rubber Curing Chemicals

Many polymers cannot be properly used without first being cured via the addition of a vulcanizing agent. Without the addition of a curing agent, polymers are pliable and tacky. Curing transforms the polymer into a more durable, resilient product.

The right curing agent depends on the base polymer, the processing conditions, and the physical and service requirements of the finished compound. They come in a variety of forms, including powders, liquids and filler supported formulations. The right form for your compound depends on the mixing conditions.

If you’re not sure which is right for your compounding needs, our material experts can help you decide!

The Properties and Diverse Uses of Vulcanizing Agents

Chemical curatives like magnesium oxide, peroxide, and sulfur are key components in a wide variety of products and applications, including:

  • Automotive parts
  • Golf ball cores
  • Conveyor belts
  • Footwear soles
  • Adhesive tapes
  • Wire and cable
