OT 20 is a polymer sulfur with high thermal stability, which is insoluble in rubber. It can prolong the scorch time of rubber compound, prevent the migration of sulfur and improve the viscosity of rubber surface;
OT 20 is pollution-free and does not change color.
OT 20 is generally used in unsaturated rubber formula with high sulfur content, especially when the number of added parts exceeds the solubility of soluble sulfur;
OT 20 has low migration rate, even dispersion and long scorch time in rubber, which can improve the adhesion between copper coated steel wire and rubber, so it is widely used in tire steel wire adhesive formula and OTR tire;
OT 20 can also be used in vulcanized rubber products with high performance requirements.
