GENERAL DESCRIPTION & APPLICATIONS

Blowing agents, also called Foaming agents, can be classified as Physical and Chemical Blowing Agents. Physical blowing agents are not under chemical changes during processing. Physical blowing agents are in forms of liquid or compressed gas which will transfer state into gases or low boiling liquid during processing causing resins into cellular structure. Chemical Blowing Agents are mainly solid form of hydrazine derivatives include Azodicarbonamide; p,p'-Oxybis(benzenesulfonyl hydrazide); 5-Phenyltetrazole; p-Toluene sulfonyl semicarbazide; Trihydrazine Triazine; They commonly release gases such as nitrogen, carbon dioxide, carbon monoxide or ammonia. But ammonia is not desirable as it effects on degrade of resins. There are nonazo blowing agents releasing carbon dioxide such as sodium borohydride.

GENERAL DESCRIPTION OF NITROSO-
Nitroso is the prefix for NO- radical with trivalent nitrogen also known as hydroximino; oximido. Substances in which this group is attached to an oxygen atom are called nitrites (esters of nitrous acid); those in which the nitroso group is attached to a metal ion are called nitrosyls. Nitroso (-N=O) groups and azo (-N=N-) groups impart colour to the compound as these groups absorb light of characteristic wavelengths. Nitroso groups are strongly electron withdrawing and more similar to the C=O than the nirto group. Nitroso compound tends to dimerise. There is polarisation of the N=O bond and so behaves as a weak C=O. It undergoes addition of nucleophiles and condensation with primary amines and the anions of active methylene compounds. Nitroso groups are useful in addition and condensation reactions, stable nitroxide radical preparations, and isomerization to oxime. Oxidation undergoes readily with peracids, this is not available with nitro groups. Nitroso compounds are useful intermediates for the synthesis of target materials. Certain niroso derivatives are used as vulcanization accelerator by direct reacting with peroxy-free radical to tie up free radicals and adhesion promoter between metal and rubber.
