◆    Performance:  
    -HD OT 20 is a polymer sulfur with high dispersibility, 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;
    -HD OT 20 is pollution-free and does not change the color.

◆    Application:  
    -HD OT 20 is generally used in unsaturated rubber formulations with high sulfur content, especially when the number of added parts exceeds the solubility of soluble sulfur;
    -HD OT 20 has a low migration rate, even dispersion and a long scorch time in rubber, which can improve the adhesion between copper coated steel wire and rubber. Therefore, it is widely used in tire steel wire adhesive formulations and OTR tires;    
    -HD OT 20 can also be used in vulcanized rubber products with high performance requirements.          

◆     Packaging: Paper/plastic packages with a net weight of 25kg per package.  

◆     Transportation: Meet the general transportation conditions of chemicals and avoid mixing with alkaline substances.
