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) 

"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
