  Use Characteristics:

  Pre-dispersed Trustone®S-80 is recommended where a more eco-friendly material, higher productivity and better dispersion is required. This often translates to lower bottom-line costing.The active ingredient, soluble rhombic sulfur (S8), is still today the most common curative agent for unsaturated elastomer. Trustone®S-80 is a curing agent for all natural and synthetic rubbers, which require a quick incorporation in the mix and an excellent dispersion of the sulfur. Due to the homogeneous dispersion in the rubber the occurrence of localized over-cured zones is avoided, which ensures an improved resistance against ageing and dynamic fatigue. The good dispersion of sulfur is of particular advantage in soft compounds, in which a problem-free distribution of the sulfur is often very hard to achieve.

   
  Processing Advantages The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easy quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective sulfur is assured.
   
  Dosage: Usually 0.3~3.0phr; up to 55phr for ebonites; Adjustments can be made according to actual effect.
   
  Applications
  Obviously for soft compounds: light-colored compounds which must be free of sulfur stains, rubber articles which have to withstand dynamic stress.
