What are Yasho's rubber chemicals?

Yasho’s Rubber chemicals include Accelerators / Antioxidants / Co-agents for processing EPDM, SBR, NBR, ECO, Acrylic, NR and more. Specific examples are PIPERIDINIUM PENTAMETHYLENE DITHIOCARBAMATE (QUREACC®TBzTD) and TETRABENZYL THIURAM DISULFIDE (ZINC BENZENE SULFINATE DIHYDRATE) (QUREANTI®NDBC).

Can microalgal biomass be used as filler in rubber composites?

In this study, the researchers investigated using microalgal biomass as filler in rubber composites. They assessed the filler-matrix interaction by evaluating the processability, mechanical characteristics, Payne effect, and swelling properties of the MB/CB-filled composites and compared them to CB-filled composites.

Is MB/CB a good dispersion in rubber matrix?

This suggests that good dispersion of MB/CB in rubber matrix and strong interaction between them. It is notable that, in accordance with the SEM results, the dispersion of biomass/CB in NBR vulcanizates is superior to that of MB/CB in SBR vulcanizates, as evidenced by an increase in upturn \ (\varPsi _ { {Up}}^ { { – 1}}~\) value.

Why are CB and MB soluble in NBR rubber 61?

This is because CB and MB are partially soluble in organic solvents, which is why they are used as filler in NBR rubber 61. Conversely, when the concentrations of MB were increased until 30 phr, the soluble fractions dropped.

Are biomass/CB fillers effective in strengthening cured rubber?

The effectiveness of biomass/CB fillers in strengthening the cured rubber is revealed by the tensile characteristics of the rubber composites. In comparison to gum vulcanizates of NBR and SBR, it is evident from Fig. 11 that both kinds of rubber-filled vulcanizates possess high strength.

Can biochar replace carbon black in rubber blends?

In an effort to find more sustainable alternatives, researchers have explored the use of biochar derived from coppiced hardwoods as a partial replacement for carbon black in rubber blends containing natural and butadiene rubber.
