Blowing agent
Blowing agent is the substance that makes the object material into a hole, it can be divided into chemical blowing
agent and physical blowing agent and surfactant three categories. Chemical blowing agents are compounds that, when
heated and decomposed, release gases such as carbon dioxide and nitrogen and form fine pores in the polymer composi
-tion. Physical blowing agent is the foam pores are formed through the change of the physical form of a certain subs
-tance, that is, through the expansion of compressed gas, volatilization of liquid or dissolution of solid; Foaming
agents have high surface activity, can effectively reduce the surface tension of the liquid, and on the surface of
the liquid film double electron layer arranged to surround the air, forming bubbles, and then a single bubble compo
-sed of foam.
Use: Blowing agent AC is a blowing agent with large volume and wide use. It is used in PVC, polyethylene, polypropylene,
polystyrene, polyamide, ABS and rubber and other synthetic materials. Widely used in slippers, soles, insole, plastic
wallpaper, ceiling, floor leather, artificial leather, insulation, sound insulation materials such as foam. Foaming agent
AC has the characteristics of stable performance, non-flammable, non-pollution, non-toxic and tasteless, no corrosion to
the mold, no staining to the products, decomposition temperature can be adjusted, does not affect the curing and forming
speed. This product can be normal pressure foaming, pressure foaming, even foaming, fine pore structure is ideal.
