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.

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 and wire and cable.
