Chemical Foaming Agents

Azodicarbonamide

Product	Form	Decomp Temperature (Deg C)	Gas Volume (ml/g)	Particle Diameter (μ)	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.

Modified Azodicarbonamide

Product	Form	Decomp Temperature (Deg C)	Gas Volume (ml/g)	Description
AC-5000	Powder Paste Masterbatch Micro-Pellet			A modified nitrogen blowing agent with a low decomposition temperature and medium size particle diameter. AC-5000 can be used in sponge rubber, vinyl
AC-6000	Powder Paste Masterbatch Micro-Pellet			A modified nitrogen blowing agent with a low decomposition temperature and small particle diamter. AC-6000 can be used in flexible PVC and most elastomer.
Unifoam AZ® MI-25T	Powder Paste Masterbatch Micro-Pellet			A modified foaming agent with 160˚C decomposition temperature and with 178 mL/g gas evolution. Suitable for expanding rubber, thermoplastics, and EVA.
Unifoam AZ® MI-25SO	Powder Paste Masterbatch Micro-Pellet			A blend of exothermic and entothermic foaming agents designed specifically for use in rigid PVC foams. Has a decomposition temperature of 180˚C and a gas.
Unifoam AZ® MI-25TZ	Powder Paste Masterbatch Micro-Pellet			A blend of foaming agents and activators designed specifically for use in rigid PVC. A 160˚C decomposition temperature and 135 mL/g gas yield, endothermic.
Unifoam AZ® MI-25TC	Powder Paste Masterbatch Micro-Pellet			A modified foaming agent designed specifically for use in rigid PVC foams. It is constructed from a specialized blend of several foaming agents and auxiliary.

Hydrazine Compounds

Product	Form	Decomp Temperature (Deg C)	Gas Volume (ml/g)	Particle Diameter (μ)	Description
OBSH-8	Powder Masterbatch	150-164	124+/-6	5-10	An 8μ foaming agent suitable for use in open and closed cell rubber, LDPE, EVA, and soft vinyl. OBSH-8 has a low decomposition temperature and can be used.
TSH	Powder Masterbatch				General purpose low temperature foaming agent. Suitable for expanding liquid polysulfide rubbers at ambient temperature.
BSH	Powder Masterbatch				A non-staining, non-discoloring, non-toxic, odorless nitrogen foaming agent. Has a decomposition temperature of 90-105˚C and 115-120 mL/g gas evolution.

Carbazides

Product	Form	Decomp Temperature (Deg C)	Gas Volume (ml/g)	Description
TSS	Powder Masterbatch			TSS delivers gas at higher temperatures than other foaming agents. Suitable for use in ABS, low melt index Polyolefins, impacted PS, and rigid PVC. 140-150mL/g gas yeld; 224-235˚C decomposition temperature.

Activators & Stabilizers

Product	Form	Decomp Temperature (Deg C)	Gas Volume (ml/g)	Description
Activator N46	Powder Paste Masterbatch			A non-dusting, non-staining urea activator used to lower the decomposition temperature of azodicarbonamide blowing agents in rubber compounds. Reacts with amine by-products of azodicarbonamide to reduce the amine odor.
Activator BM	Powder Oiled Powder Paste Masterbatch			A strong organometallic activator for ADC blowing agents which produces a whiter foam than pure ADC. Non-discoloration allows for a decrease in titanium dioxide without sacrificing whiteness.
Activator TM	Powder Oiled Powder Paste Masterbatch			A strong organometallic activator for ADC blowing agents which produces a whiter foam than pure ADC. Non-discoloration allows for a decrease in titanium dioxide without sacrificing whiteness.
Stabilizer Q	Powder Oiled Powder Micro-Pellet			Heat stabilizer for calendared rubber after expansion and for PVC foams.
