Application:

Application in Unsaturated Rubber: Sirubtis HS OT 20 is particularly used in formulations of unsaturated rubber where the amount of sulfur exceeds the solubility limit of soluble sulfur in the compound.

Improving Adhesion: It has a low migration rate and can improve the adhesion between copper-coated steel wires and rubber, making it widely used in tire steel wire adhesive formulations and OTR (Off-The-Road) tires.

Extended Scorch Time: The product can extend the scorch time of rubber compounds, preventing sulfur migration and enhancing the tackiness of the rubber surface.

FAQs:

Title

-HS 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;

-HS OT 20 is pollution-free and does not change the color.
