Actmix ® Curing Agent OT20-70GE F500
Curing Agent Insoluble Sulphur OT20
Active ingredients |
Insoluble Sulphur IS
Molecular Formula:Sn
Molecular Weight:32n
CAS No.:7704-34-9
EINECS No.: 231-722-6 |
Properties:
Insoluble Sulphur OT20 contains 75% or above of modified polysulfur (which is insoluble in solvents and CS2).. it can be used in natural or synthetic rubber to prevent migration, and frost of sulfur, and keep the storage safety of rubber materials
. To delay the change time of Insoluble Sulphur into soluble Sulphur, OT20-70 should be added before mixing, and the sulfur temperature should not be too high .
Dosage: one to five portions.
Uses: Tires, conveyer belt, and turn tire, rubber hose, sealing ring, rubber roller, and other industrial products

Compared with traditional powdered insoluble sulphur IS, Actmix ®OT20-70GE F500 has the following advantages:
master batch IS60-75 is pre-dispersed with rubber carrier, thus can effectively ensure the activity of insoluble sulphurIS.
No clay domain appears with master batch at room temperature
Has low Mooney viscosity at low temperature such as 50°C to improve disperse quality
While granulation, master batch can filtering to lower rejection rate.
Has good compatibility with different rubbers |
