BLOWING AGENT - MIKROFINE ADC-21

MIKROFINE ADC-21 is a chemical blowing agent based on Azodicarbonamide. It is useful in the processing temperature range of 155 0C - 175 0C for foaming rubber compounds particularly based on EPDM rubber.

CHARACTERISTICS

Chemical Compostion : Specially modified Azodicarbonnamide
Physical Form : Pale Yellow Fine Powder
Moisture Content : 0.2% max
Solubility : Practically insoluble in water.
Decomposition temperature in air (Capillary tube method) : 158  20C
Gas Composition : Mainly nitrogen and carbon monooxide
Gas/gram : 185 cc at STP

SPECIAL FEATURES

APPLICATIONS

MIKROFINE ADC-21 is recommended for use

DOSAGE

0.5-3.0 PHR depending on the polymer used and extent of expansion required.

STORAGE

MIKROFINE ADC-21 should be stored

FLAMMABILITY

MIKROFINE ADC-21 will burn only when exposed to flame. Thermal decomposition of MIKROFINE ADC-21 causes evolution of fumes resembling smoke. Large quantity of water should be used to fight fire.

TOXICITY

MIKROFINE ADC-21 is of low toxicity by skin contact and is mildly irritating to the eyes. Its decomposition residues are also of low toxicity.

HANDLING

Though MIKROFINE ADC-21 is substantially free from handling problems, care should be taken to prevent its contact with skin and eyes. It is necessary to avoid dusty conditions because of the possiblity of respiratory sensitisation.

PACKING

MIKROFINE ADC-21 packed in 25 kgs HDPE woven bags with polythene liners inside.
