2, NC white blowing agent, also known as alkali (commonly known as soda), its gas generation and decomposition temperature is much lower than the yellow blowing agent, gas generation is about 110 or so, decomposition temperature of 130-150 ℃ or so.
3, universal foaming agent, chemical name sulfonylhydrazine, decomposition temperature 110-190 ° C, the amount of gas with the physical conditions of change, the main advantages of foaming holes delicate, such as the same volume range, the number of foaming holes, the pore size is small. Widely used in high-grade shoe sole plastic and aviation equipment products, as well as civil high-end foam products.
