Performance:
-HD OT 20 is a highly dispersible polymerized sulfur that is insoluble in rubber. It can prolong the scorch time of the rubber compound, prevent sulfur migration, and improve the viscosity of the rubber surface;
-HD OT 20 is pollution-free and does not change color.
Application:
-HD OT 20 is generally used in unsaturated rubber formulas with a high sulfur content, especially when the added amount exceeds the solubility of soluble sulfur;
-HD OT 20 has a low migration rate in rubber, uniform dispersion, and a long scorch time, which can improve the adhesion between copper-plated steel wire and rubber. Therefore, it is widely used in tire steel wire bonding rubber formula and OTR tires;
-HD OT 20 can also be used in vulcanized rubber products with higher performance requirements.
Packaging form:
Paper-plastic packaging bag packaging, net weight of each bag is 25kg.
Transportation conditions:
Meet the general chemical transportation conditions and avoid mixing with alkaline substances.
