Cure-Rite® accelerators control the rate of vulcanization, which can improve rubber manufacturing productivity and ensure the development of desirable properties―such as strength, elasticity, modulus, and oxidation stability―prior to curing.
Most molded rubber goods are subject to a variety of operations involving heat to mix ingredients and shape the article. During these operations, it is important that curing does not take place until processing is complete. Cure-Rite® Accelerators can be used to delay “scorch time” while still achieving a fast overall “cure time.”
Cure-Rite rubber additive technology includes low nitrosamines, delayed action types, sulfur donor types (sulfenamide or sulfur donating), and products tailored for superior scorch protection and easy dispersion post-mixing.
Sulfur-donating accelerator improves compression set, reversion resistance, and oxidative stability.
