4: Usage;
Commonly used in the treatment of carbon black, sio2 and other inorganic fillers, not the ability of activating agent, coupling agent role, also has cross-linking agent, softener, and reinforcing the role of agents in the rubber industry as a reinforcing agent and curing agent. Can be used for natural rubber, isoprene rubber, styrene butadiene rubber, butadiene rubber, butyl rubber, neoprene, butyl rubber, halogenated butyl rubber, EPDM rubber, and the oil-filled rubber adhesive, Also in the rubber can be used with gel.

Effectments:
1, unvulcanized rubber
( 1) reduce the Mooney viscosity; ( 2) reduce the scorch phenomenon; ( 3) curing degree increased; ( 4) mixing, rolling, extrusion features greatly improved.
2, vulcanizate
( 1) tensile strength increase; ( 2) increase the tensile strength; ( 3) reduce the permanent deformation; ( 4) heat and dynamic characteristics have been improved; ( 5) improved wear properties of silicon: ( 6) tear strength improved; ( 7) and other substances in water, swelling improved.
