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.

MIKROFINE ADC-21 is recommended for use
0.5-3.0 PHR depending on the polymer used and extent of expansion required.
MIKROFINE ADC-21 should be stored
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.
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.
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.
