Function & Compounding

Rhenofit 1600
Combination of urea derivatives and dispersing agent
Rhein Chemie Corporationï

Sp.gr. approx. 1.25; light-colored aqueous paste

Blow promoter and deodorizer as well as vulcanization activator with built-in scorch retarder.

Kenmix
Diak #1/N 2/1
Flow Polymers LLCï

Sp.gr. 1.15

Activator in paste form in Kenflex N.

Kenmix

Flow Polymers LLCï

Sp.gr. 1.15

Activator in paste form in Kenflex P.

D-B-A Accelerator
Dibenzylamine-monobenzylamine blend
Chemturaï

Sp.gr. 1.01; pale-yellow free flowing liquid; good storage stability.

For NR, SBR rubbers and latices, NR reclaim; affects air cures ranging from 24 hrs. at room temp to 20 min at 100°C; retarded by clay and other acidic materials; action with xanthates or carbon disulfide enhanced by thiazoles and thiurams; non-discoloring, non-staining; vulcanization requires zinc oxide and sulfur; fatty acids not necessary and can retard cure; can apply carbon disulfide by painting or dipping compounds thus eliminating danger of precure; for processing and applications see C-P-B.
