 The mechanism of MST® 100 pure zinc oxide Made in China as a foaming accelerator:

MST® 100 pure zinc oxide Made in China plays a role in helping foaming in EVA, which is helpful for the adhesion and foaming of EVA. The decomposition temperature of pure AC foaming agent is between 180-220. This decomposition temperature is relatively high for some products, so it is necessary to add a foaming agent. MST® 100 pure zinc oxide Made in China is a commonly used foam promoter.

1) The peripheral electron arrangement of the zinc ion of 100 pure zinc oxide Made in China has an empty orbital, and the molecular structure of the AC blowing agent has a lone pair of electrons for nitrogen and oxygen. The cloud concentration flows to both sides, and the degree of overlap in the middle is reduced, causing the -NC- bond to be easily broken, which makes the AC activation and decomposition.

2) The cyanic acid formed by the decomposition of AC blowing agent is easy to form a viscous and firm metal complex on the surface of the mold, which shortens the mold removal cycle, while 100 pure zinc oxide Made in China can reduce scaling and prolong the mold removal cycle.

The application of MST® 100 pure zinc oxide in EVA products:

EVA products generally use 100 pure zinc oxide Made in China with a zinc content of 99.7%, and some medical uses nano-zinc oxide. EVA products include: eva floor mats-foam floor mats for children, as well as yoga mats, moisture-proof mats, etc.;  eva insulated pipe covers-used to prevent water pipes from bursting in winter; other products include refrigerator ducts and gas Pipes, civil construction plates, containers and daily necessities, etc., can also be used to make packaging films, gaskets, medical equipment, and can also be used as hot melt adhesives, cable insulation layers, etc.
