China Star Materials Nickel dibutyldithiocarbamate (Antioxidant NBC)

China Star Materials Nickel dibutyldithiocarbamate (Antioxidant NBC) is bottle-green powder. It can be used as an antiozonant for CR, CSPR, ECO, SBR, NBR, etc. In CR, it can improve the thermal resistance of rubber, and reduce the discoloration under the sun, and it can slightly retard the vulcanization.

    Features & Benefits

    Functions

    It has excellent protective character to ozone and oxygen, TPPD can be used as Antioxidant for CR, NR, BR, SBR and their latexes. TPPD can inhibit copper oxidation and manganese oxidation, and especially can inhibit the damage to fiber materials by chlorine released during CR's aging. TPPD is dispersible, so it can be directly added into rubber, or be added into latex in the form of aqueous dispersoid. When TPPD is used in CR with Antioxidant ODA as co-reagent, it will perform its best thermal resistance, reduce the plasticity of unvulcanized CR, and decrease the degree of shrinkage during calendering, so is helpful to adjust the size of semi finished articles.
