2. Excellent foaming effect, giving the filler good dispersibility, can make foaming bubble dense and uniform, very good control foaming rate.
3. Reduce the cost of the recipe.
4. High cost performance, good weather resistance, good resistance to precipitating and forming process, reduce the formula cost by 10%.
5. Excellent thermal stability and lubrication.
How to use foaming agent in PVC foaming board?
The production of PVC foaming plate generally adopts three different foaming agents, such as heating type, heat-absorbing type or endothermic and exothermic compound balance type. Ammonium azodiformate, also known as AC, belongs to azotized activator. AC foaming agent decomposition temperature is high, up to 232 deg.C, far beyond the PVC processing temperature, when used to reduce the decomposition temperature.
Exothermic foaming agent has a high foaming rate of about 1900-260ml /g, which is fast and extremely hot, but the foaming time is short and sudden. Are too much, so when the AC blowing agent gas evolution is too big, can make the pressure in the bubble growth is fast, bubble hole size grows too large, rapid release gas, make the bubble pore structure, pore size distribution, and formation of open hole structure, can produce larger bubbles and cavitation in local. In the production of foamed plastic products, the exothermic foaming agent AC shall not be used alone, and should be used in conjunction with the heat-absorbing foaming agent, or with the combination of heating and exothermic chemical foaming agent. The inorganic foaming agent - sodium bicarbonate (NaHCO3) is a heat-absorbing foaming agent, although the foaming rate is low, but the foaming time is long, and mixed with AC foaming agent can play a complementary and balanced role. Exothermic foaming agent could improve the ability of gas of endothermic foaming agent, endothermic blowing agent and the cooling and stabilize the balanced and release the gas, the decomposition and inhibition of thick plate internal heat degradation, reduce the residual precipitation, has whitening effect.
