Austin Black 325 by CFI Carbon Products is a processing aid. Exhibits excellent dielectric properties, chemical and ultraviolet resistance. It readily disperses in natural rubber, synthetic rubbers, and plastics, which reduces mixing time without causing agglomeration or sacrificing the dispersion of other ingredients. The volatile matter (17% to 20%) contains inherent oils that act as an internal plasticizer and dispersing aid. It will not absorb moisture and can improve air retention and moisture permeation properties in rubber compounds. Austin Black 325 also facilitates air release from compounds which reduces bubble and blister problems.
