Summary: | The invention pertains to 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. The invention also relates to a particle-elastomer composition comprising:
(a) 100 parts by weight of at least one natural or synthetic elastomer, particularly rubber;
(b1) 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; or
(b2) 0.1 to 20 parts by weight, preferably 1-15 parts by weight of a peroxide; and
(c) 0.1 to 20 parts by weight, preferably 1-10 parts by weight of the aramid particle. |
