Curing Agents

Curing Agents

Suppliers of Peroxide, Magnesium Oxide & Rubber Curing Chemicals

Many polymers cannot be properly used for their intended purpose without first being cured via the addition of a vulcanizing agent. Without the addition of a curing agent, polymers are pliable and tacky. Upon curing the polymer is transformed into a more durable, resilient product.

The selection of the appropriate curing agent is dependent on the base polymer, the processing conditions and the physical and service requirements of the finished compound. Curing agents come in a variety of forms, from powders and liquids to filler supported formulations. The selection of form is dependent on the mixing conditions of the compounder. For more information on which curing agent is suited to your compound, contact H.M. Royal.
