The principle of the foam rubber inflatable suit is to inject gas into the plastic material through physical or chemical foaming technology to form a foam material with a microporous structure. Specifically, the working principle of the foam rubber inflatable suit can be divided into the following aspects:
Physical foaming method: This method is to inject gas into the plastic paste melt under high pressure, and then reduce the pressure to release the gas to form countless small holes. The physical foaming method is low in cost and does not leave any residue in the foamed plastic, nor does it have a negative impact on the performance of the plastic.
Chemical foaming method: Gas is generated through chemical reactions to expand and foam the plastic. This method is usually carried out under heating conditions, and the chemical foaming agent decomposes and releases gas, thereby forming bubbles in the plastic.
Mechanical foaming method: Gas is mixed into the material using mechanical stirring, and then a foam plastic with bubbles is formed through a shaping process.
