How is the sponge made?

Sponge foaming has the following five steps:

Nucleation reaction: Simply put, the silicone oil evenly dissolves the components together, and it acts as an intermediary to form a kind of nucleus! (It is the formed cell. (The time is about 3 to 5 yarns)
Milky white reaction: It is a process of increasing the resistance under the catalysis of various small materials. (The time is about 6-12 seconds)
Foaming reaction: The heat and gas generated by the reaction of TDI and water after the consistency of the material increases continuously, which causes the material to foam and increase its volume! (Time is 70 seconds to 120 seconds)
Gel reaction: When the temperature of the foam body reaches a certain level, the two main ingredients will gradually open to gel under the catalysis of T9. This process is called ~ (about 30 yarns ~ 70 seconds)
Maturation reaction: After gelation (exhaust steam), the sponge starts the real post-maturation reaction stage (approximately 12-24 hours)
