Eva molding is a common raw material for household products in life. But people may not know about EVA material; many people think it is a kind of colored sponge foam. All the disadvantages of foam sponges in EVA have been improved; for example, EVA material compared to the traditional foam sponge flame retardant has been dramatically improved. So what is the composition of EVA material?


The E refers to Ethylene, and VA refers to Vinyl Acetate, the whole process for Ethylene Vinyl Acetate, as Eva foam suppliers generally call it EVA or E/VAC. These names refer to the same substance, where the content of VA is generally between 5% to 40%. We introduce vinyl acetate monomer in the molecular chain, so reduce the high crystallinity, improve the toughness, impact resistance, filler compatibility, and heat-sealing performance.


So EVA is a product of continuous improvement of the formula; today, EVA has many applications. The performance required in different areas varies slightly; we can adjust the final performance of EVA products by adjusting the proportion of various ingredients. If you are interested in EVA moulding, please contact us. We will contact you in time.
