White (NC) foaming agent
Product Title：PVC foam board inorganic white foaming agent ultrafine sodium bicarbonate baking soda
product presentation：The white foaming agent, mainly composed of carbonate compounds, is a heat-absorbing foaming agent. It is mainly used for PVC, PS, TPR and other materials that require no formic acid in the foaming process. This type of foaming agent does not require the use of activators. Its decomposition depends only on the provided heat and processing conditions, friction and pressure. The foaming decomposition is relatively gentle, and its decomposition products are mainly CO2, which will not corrode the production and processing equipment. The residual substances from its decomposition are white, which does not affect the color of the product. The p
roduct has good whiteness and is a green and environmentally friendly product.
