Chemicals in a Rubber Compound - NSR 20, Accel CS, Accel DPG, Anitiox Q, Antioz PMB

I have a recipe for a rubber compound and am trying to understand some of the ingredients.


The ones I do not recognize are


Compound A


* NSR 20
* Accel CS
* Accel DPG
* Anitiox Q
* Antioz PMB


Compound B


* SMR 20
* Accel NS
* Accel DPG
* PVI


Compound C


* Orox HR
* Orac CS
* Orac TMTD


Is there a place to look these up on the web?




NSR 20 and SMR 20 are natural rubber (Nigerian Standard Rubber and [Standard Malaysian Rubber](http://www.klpk.com.my/content/display/article/site:klpk-param:standard_malaysian_rubber-link:7546)) 


"Accel" and "Orac" mean accelerator. 


Accel DPG is diphenyl guanidine.


"Antiox" and "orox" mean antioxidant


"Antioz" means antiozonant 


"Orac CS" is likely N-cyclohexyl-2-benzothiazole sulphenamide 


"Orac TMTD" is likely Tetramethylthiuram disulfide


"PVI" may refer to pre-vulcanization inhibitor
