NOCIL Rubber Prevulcanization Powder

Pilgard PVI is widely used in the manufacture of almost all rubber products based on sulphur curable rubbers. Pilgard PVI is not used in latex compounding and the rubber products intended for contact with food/drugs. TYPICAL DOSAGES: Typical dosages of Pilgard PVI required to produce the desired scorch delay depend on the type of rubber, loadings of reinforcing fillers, selection of accelerator type and dosage, sulphur dosage, etc. used in the compounding formulations and the processing operations required to be performed for the product manufacture under the existing processing conditions. Also as stated earlier, Pilgard PVI dosages have to be fine tuned to achieve only the desired level of processing safety and mould flow time and excess dosages of Pilgard PVI have to be avoided. Ambient temperatures, process water temperatures and modifications in processing machinery with respect to processing temperatures or speeds can influence Pilgard PVI dosages considerably.
