To see the above Video , get idea.
Composition or EVA Formula:01
- EVA = 50 kg
- Calcium Carbonate = 30 kg
- Zinc Oxide = 0.800 kg
- Stearic acid = 0.900 kg
- Zinc Stearate = 0.500 kg
- Titanium di Oxide = 0.500kg
- Azo di carbon Amide = 2.800 kg
- Di-cumyl per oxide = 0.500 kg
There are a lots of Formulations.
