What Is The Process Of Foamed Plastics?
The forming and setting process of foam plastics generally can be divided into three stages: the formation of I bubble nucleation II bubble growth III bubble stability.
Foaming molding should first form a large number of uniform and fine bubble cores in plastic melt or liquid, then expand into the required foam. Finally, foam structure will be fixed through fixed speech to get foam products. It is worth noting that the forming mechanism and influence factors of these three stages are different.
