Foaming Agents
We market 2 types of foaming agents;
a) Synthetic – suitable for densities of 1000 kg/m3 and above.
b) Protein - suitable for densities from 400 kg/m3 to 1600 kg/m3.
 | Foams from our protein foaming agents comes from natural sources and have a weight of around 80 g /liter and expansion of about 12.5 x using Portafoam foam generator. They generally are more stable than synthetic foams but have a shorter shelf life of about 12 months in open conditions. They also give a higher strength of concrete compared to synthetic foams. |
Dilution of foam concentrate can vary from 1:33 to 1: 39
1 liter Noraite PA-1 + 39 lit water = 40 lit premix foaming solution
40 lit premix expands to about 500 lit stable foam @ about 80 g/lit foam weight
| Synthetic foams have a density of about 40 g/liter with an expansion of about 25 x using Portafoam. They are very stable at concrete densities above 1000 kg/m3 and give good strength. Their shelf life is about 16 months under sealed conditions. |
1 liter Noraite SA-1 + 19 lit water = 20 lit premix soln
20 lit premix expands to 500 lit stable foam at about 40 g/lit foam weight
Our foaming agents are of top quality and have been proven by its usage in many countries around the world for various uses such as block production, in-situ concrete, decorative concrete and void filling. For further inquiries contact :
