◆
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.
