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. Applications include automotive parts, golf ball cores, conveyor belts, footwear soles, adhesive tapes and wire and cable.

CTPI | Toray | Rubber Curing Chemicals | CTPI is used as an inhibitor of premature vulcanization of synthetic and natural rubbers, providing the rubber compounder with a better means of controlling scorch safety. CTPI is most effective with thiazole and sulphenamide accelerator systems and the fastest curing polymers. An approximate order of response by polymer is: NR > NBR > SBR > EPDM > IIR > CR. CTPI increases processing safety without affecting vulcanizate properties, aged properties, fatigue life, stain, discoloration, or porosity. Typical loading levels are 0.1 to 0.4 phr. |
