First of all, the main materials of EVA are EVA and pigment (masterbatch). Through the foaming molding of EVA plastic particles, the ethylene-vinyl acetate copolymer itself is non-toxic, even food-grade and edible. Because many domestic enterprises are not formal now, the main ingredients of EVA floor mats produced with recycled materials have changed, not only EVA, but also many other plastics, including PVC, so this taste is very bad for children! ! ! Although eva material is environmentally friendly and nontoxic, mats and slippers made of eva are toxic.

Because foaming products such as floor mats and slippers need foaming agent when eva is used for foaming, and the substances contained in eva combine with those in foaming agent to generate formamide, which is a low toxic compound.

EVA has a wide range of applications, and its market consumption is increasing every year in China, especially in the shoemaking industry, which is applied to the soles of middle and high-grade travel shoes, hiking shoes, slippers, sandals and interior materials. It is also widely used in new energy fields, such as photovoltaic materials and solar cell adhesives.
