Abstract
An aramid particle containing a peroxide radical initiator wherein the particle contains 3-40 wt % peroxide radical initiator based on the weight of the aramid particle. Also, disclosed is a particle-elastomer composition having 100 parts by weight of at least one natural or synthetic elastomer, such as rubber; 0.1 to 20 parts by weight of a peroxide or 0.1 to 25 parts by weight of sulfur, an amount of a sulfur donor providing the equivalent of 0.1 to 25 parts by weight of sulfur, or a mixture of sulfur and a sulfur donor to an equivalent total of 0.1 to 25 parts by weight of sulfur; and 0.1 to 20 parts by weight of the aramid particle.
