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.
Packing: Net weight 20kg/PE bags lined carton; Net 600 kg/pallet. Pallet size: 1.1x1.1x1m
Storage: In original closed containers under cool and dry conditions max. 2 years.
Handling: Consult material safety data sheet (MSDS) for additional handling information.
Compared to traditional S powders, Trustone?S-80 allows:
Dust free products with a complete filtration up to 63μm, no skin sensitization, avoiding of burning or even explosion when mixed with air.
Effective guarantee of stability and activity of sulfur due to pre-dispersed master-batch.
Tack free products at room temperature, convenience and accuracy on ingredients.
Lower Mooney viscosity at lower temperature (50°C), higher quality of dispersion, no appearance of brown-spot.
Impurity free, blocked filter free of extrusive products, scrap rate reduction and higher productivity thanks to filtration.
Wider compatibility with other elastomers.
Benefits of Trustone? Polymer-bound pre-dispersed rubber chemicals include:
1. Fast and High redispersibility in rubber compound
2. More accurate weighing & faster mixing
3. Greater stability of active chemicals due to encapsulation
4. Safety of operation - reduced leverls of hazards of skin irritants or inhalation
5. Conformity to EU legislation on handling chemicals
