In the name of Allah. Dear sirs/Madam. I attempted to make a PVC compound.My fibnal product has tend to yellow colour.I used azodicarbonamide as my blowing agent. Other materials were completely white. Do you have any offer to me contributing to the white final matter? Do you know any material have great clean white color in PVC compounds? Do you know any substitute of blowing agent with similar foaming power but whit color ? Let me explain by another way. I need final clean white product.What matters are effective in PVC compound to final color and how can I find better replacements? Best Wishes.

this discoloration. I suggest you ask your blowing agent manufacturer for a suitable additive (activator, kicker, stabilizer, etc.) to lower activation temperature or for a suitable endothermic blowing agent for your purpose ...

Most followers of Allah use C4 as their blowing agent ;)
