Foaming method of EPE productsFoaming method of EPE products
EPE foaming products are widely used in our life. They are all made of EPE foaming. What is the foaming method of EPE foaming?
The physical foaming method of EPE foaming products: the low boiling point liquid dissolved in polymer melt is evaporated to make it vaporized and foamed, or the inert gas can be dissolved in the plastic melt or paste under pressure, and then the gas can be released under reduced pressure, so as to form the air hole in the plastic, and then the hollow ball is added to the plastic to form the foaming body and foamed, etc
Chemical foaming method of EPE foam cloth products: chemical foaming method is to use chemical method to produce gas to make plastic foam, or to heat the chemical foaming agent added into plastic to decompose and release gas to foam, or to use the gas released by chemical reaction between plastic components to foam
The cost of the physical foaming agent used in the physical foaming method is relatively low, and the foaming agent has no residue after foaming, which has little influence on the properties of the foamed plastics. The injection process of the foamed plastics using the chemical foaming agent is basically the same as the general injection process, which is completed in the injection molding machine
