We are the supplier of Insoluble Sulphur in New Delhi, India. Insoluble sulphur is primarily used in the rubber industry. Its advantage over ground natural sulphur is that it does not cause bloom, and that it does not dissolve and migrate in rubber. The S8 ring molecules present in soluble sulphur at room temperature open at temperatures above 158 °C, allowing chains of sulphur to combine with one another to form polymeric sulphur. Insoluble sulphur is produced by quenching the polymeric melt at low temperatures, preventing the reversion into S8 rings, leaving the polymer structure meta-stable at roomtemperature.Polymeric sulphur is insoluble in organic solvents and elastomers. In a rubber compound it is suspended, similar to inert filler, though exhibiting thermoplastic behaviour, softening to a degree at processing temperature.Most insoluble sulphurs commercially available contains over 90 % polymeric sulphur and less than 10 % soluble sulphur. These products often have very fine particles that tend to agglomerate under the influence of a static charge, which are in turn difficult to disperse in rubber. That insoluble sulphur is more likely to become electrically charged than soluble sulphur is well illustrated when insoluble sulphur is added to a gum stock on a two roll mill and sulphur particles shoot up above the nip.We are trading in Insoluble Sulphur of OOCL, the ready stock of Insoluble Sulphur OT-20 is available all the time.For further details & lowest price offer please contact us at:Email: info@arihantindia.inTel : +91-9899447115
