- What is TBBS used for?
- In natural and synthetic rubber tire compounds;TBBS is normally used alone or with small quantities of secondary accelerators in combination with sulfur. TBBS is also used in industrial rubber products with higher levels of secondary accelerators, such as the TMTD to obtain faster vulcanization cycles and improved aging resistance.
- How does TBBS loading affect compression set?
- Compression set decreased with increasing TBBS loading, as the cure system went from semi-efficient to more efficient. 9. The model compound showed less resistance to heat aging with increasing TBBS loading. Gent, A.N. Engineering with Rubber: How to Design Rubber Components; Gent, A.N., Ed.;
- What is TBBS soluble in?
- White powder/granule.The density is 1.26-1.32.it is soluble in Chloroform, Benzene, and Alcohol.and insoluble in water, gasoline, and acid/alkali with lower concentration. In natural and synthetic rubber tire compounds;TBBS is normally used alone or with small quantities of secondary accelerators in combination with sulfur.
- What is nitrosamine vulcanization mechanism of TBBS accelerated system?
- Vulcanization mechanism of TBBS accelerated system. An outstanding interest on elimination of nitrosamine generation in traditional sulfur vulcanization systems has led to introduce nitrosamine safe accelerator/s to produce safe natural rubber (NR) vulcanizates.
