Conclusion | — | Pass |
1. Delayed-Action Accelerator For Tire Compounds: Used as a primary sulfenamide accelerator in natural rubber, SBR and polybutadiene tyre compounds, it stays quiet long enough for mixing, extrusion and moulding and then cures fast once the activation temperature is reached.
2. Alternative To Morpholine-Based Accelerators: It is built on a primary amine rather than a secondary amine, the class that forms stable nitrosamines, and in the tyre industry morpholine based NOBS was replaced by sulfenamides such as TBBS.
3. For Belts, Hoses, Footwear And Moulded Goods: In technical rubber articles it gives a long processing window together with a fast, tight cure, and it can be combined with booster accelerators to tune cure rate, hardness and compression set in the finished part.
4. Suits High Alkalinity Carbon Black Compounds: It is reported to work well in carbon black filled compounds of high alkalinity, delivering scorch resistance with fast vulcanisation and high tensile strength, and it lets compounders raise the share of synthetic or reclaimed rubber.
5. Feed Forms For Low Dust Compounding: The accelerator is offered as powder, oiled powder, granule and polymer bound masterbatch so compounders can pick the form that keeps dust under control and feeds and disperses reliably in high volume mixing lines.
