Description
ADC-4 Powder
Masterbatch
195-210 220+/-10 3-5 Sulfur donor for NR and SR containing 27% sulfur which is released during vulcanization.  DTDM is non‐blooming, non‐staining, and can replace sulfur in EV and semi‐EV compounds. Usually boosted with thiazoles, sulfonamides, and thiurams. DTDM offers scorch safety and good heat aging resistance.
ADC-8 Powder
Masterbatch
195-210 220+/-10 6-8 A nitrogen blowing agent with a high gas yield and good economics. Develops a medium size, uniform cell structure.  Can be used in sponge rubber, vinyl foams, polyethylene foam, polystyrene, and ABS.
ADC-12 Powder
Masterbatch
200-210 220+/-10 10-13 A nitrogen blowing agent with a high gas yield and good economics. Develops a medium size, uniform cell structure.  Can be used in sponge rubber, vinyl foams, polyethylene foam, polystyrene, and ABS.
