Dear Sir/Madam
I studied about blowing agnets. As you probably know, Azodicarbonamide has the great ability of foaming.This blowing agent has yellow colour
(sometimes has trends to orange). When I added Azodicarbonamide to my P.V.C compounds I find serious problem.The colour of Azodicarbonamide makes my
compound trends to slightly yellow while I need White fina result. How can I neutralize the colour of azodicarbonamide in compounds?
Best Wishes

Yellows can sometimes be hidden by adding blue. Something to make the colour black. The result will be a slight greying of the white. Hopefully not
noticable.

Thank You Paddywhacker
There are two main ways to face this colour problem. First is what you told me. Adding some additives to the compound. Second way is going to
promoting the compound by the another blowing agent such as sodium bicarbonate.Other blowing agents are not useful enough because their power for
foaming is not enough as much as azodicarbonamide. ( for example sodium bicarbonate has alightly a few more than half power of foaming in contrast
with azodicarbonamide.) I hope visitors share their opinions.It is useful to increase our knowledge or increasing the power of creativity among
later visitors.
Do or not to Do? This is the primary reason of Be or not to Be.
Best wishes to all of you and Paddywhacker.

In the name of nobody, do not open new threads on the already discussed topics. Use the old thread instead. Also, provide references when you open
threads in the Organic forum section, so that I will not have to move them to Beginnings again.

I am sorry nickodem. By my vision, I attempted to expand feelings of sharing chemistry science here.
Best Wishes.
