| Property |
White solid powder. It's endothermale foaming agent. No active agent is needed in processing, the decomposition only depends on the heat and processing conditions, friction and pressure. The gas yield is CO2, which will not corrode the processing equipment. It's decomposed residue is white, which will not affect the color of product. The foam product has good whiteness, smooth surface, even and fine cell structure. It is environmental protection product, no contaminations during processing. |
