[問題] What is a chemical foaming agent, how many kinds does he have
| Foaming agent s are also called decomposable blowing agents. They can be uniformly dispersed in the resin, decomposed by heat, and can generate at least one gas. It can be divided into two types: inorganic foaming agent and organic foaming agent. Organic foaming agents are the main foaming agents used in plastics, mainly azo, nitroso and sulfonyl hydrazides. In addition, there are some foaming agent compositions, the foaming gas is released by the endothermic reaction between the two components. |
