Project Description

Insoluble sulfur

Trade Name: LEATEZ® HS OT20

Download TDS of HS OT20

Introduction:

  • Chemical Name: Polymeric Sulfur
  • Other Name: Insoluble Sulphur
  • Product form: High thermal stability and good dispersibility insoluble sulfur, 20% oil treated powder.
  • Application: Rubber Vulcanizing Agent.
  • CAS NO.: 9035-99-8

Performance:

  • The compound will be non-blooming during the storage period, can maintain uniform performance of rubber components, overcome the compound disadvantage of poor adhension because of blooming, and prevent the pollution of rubber products and molds.
  • There is no transfer phenomena in adjacent fillet, maintain the surface viscosity of compound.
  • Reduce scorching in the process of mixing and storage.
  • Shorten curing time and reduce sulfur usage to improve the ageing performance of rubber products.
  • Increase the adhesion between rubber and other materials.
  • LEATEZ® HS OT20 products also has high thermal stability, high dispersity and the most resistant to convert or restore to ordinary sulfur in the rubber processing temperature, so it can improve the safety and dispersity when compound refining in a high temperature.

Application:

  • LEATEZ® HS OT20 products are widely used in natural rubber and various synthetic rubbers.
  • LEATEZ® HS OT20 can be used for manufacturing tires, rubber belt, rubber tube, seals and other rubber products, especially for radial tire.

Packing and Storage:

  • It is packed in Kraft paper bags lined with plastic film, net weight is 25kg/bag.
  • It should be stored in a dry, clean and cool warehouse; storage temperature should be no more than 40℃. Precautions against fire, moisture, heat and compression agglomerate.
  • It cannot be mixed with alkaline and amine substance.
  • The shelf life is one year.
