Advantages of EVA products

December 14, 2022

EVA products have unique advantages. Speaking of EVA products, we all know that this sheet is a new environmentally friendly plastic foam material, EVA material manufacturers to introduce EVA sheet with light, soft, non-fading, non-leakage characteristics of children will not cause any harm.
EVA products foam production process mainly covers granulation, blending and foaming three steps. EVA granulator will EVA natural resin crushed into small enough particles, and then by the EVA foam manufacturer in accordance with a certain ratio of blending with other additives particles, different formulations of material foaming can generate different properties of EVA foam. Foam material manufacturers and then sold to EVA foam products manufacturers to produce application products, such as shoe materials. In the production process of foam sprouted from the trimmings can also be recycled and processed to produce recycled EVA foam. Recycling of recycled EVA foam is not only beneficial to the background protection, but also help enterprises to control and reduce production capital. Now the domestic mastery of recycling technology of recycled EVA foam few enterprises, especially the production of stable quality of recycled materials few enterprises. A certain amount of EVA, deionized water, PVA and emulsifier into a four-mouth flask with electric stirring, reflux condenser, thermometer, stirring, mixing and dissolving, then add VAc, enolic acid and catalyst for poly reaction, water to control the reaction temperature. When its reaction is finished, then ingest the cross-linking agent to react again, and at the end, incorporate the filler and plasticizer to stir for half an hour.
