EVA products can be divided into foam, high foam, rubber, EPE, EVA, PU and other foam products according to their materials;

According to the process flow, it can be subdivided into: grinding, cold/hot pressing, stamping, screen printing, injection molding and other products

Sports equipment: grip grinding products, EVA sponge hot pressed and cold pressed shaping products, and various material stamping products. Such as various fishing gear products, foam balls, handles, toy rockets, toy knives and guns, EVA silk screen puzzles, wheels, foot mats, packaging boxes, etc.

EVA products are widely used in industries such as electronics, sports equipment, automotive industry, toys, craft gifts, packaging, etc.

Stationery gifts: EVA pencil case, EVA letters, EVA building blocks, EVA books, EVA puzzles, EVA smiley face, EVA seal, sponge Mitsubishi, sponge cylinder, pearl cotton cylinder;

Among EVA products, colored EVA foam is the most widely used. So, how does colored EVA foam foam foam foam foam? The process is as follows:

The colored EVA foam pipe is made of EVA as the substrate, with an appropriate amount of foaming agent added and heated and pressurized to form foam. When the temperature reaches the decomposition temperature of the foaming agent, the foaming agent decomposes, releasing gas and foaming.

In addition, EVA has a certain degree of crystallinity, and its flowability is poor before the temperature reaches the crystallization and melting temperature. However, after reaching the melting temperature, the viscosity of the melt sharply decreases, and the flowability quickly increases, making it difficult to maintain the gas produced during the foaming process.

However, in order to improve the factor that is not conducive to foam forming, it is necessary to retain the gas in the base material. The ideal pore structure of the gas must be achieved by adding a crosslinking agent to crosslink the EVA molecular chains, adjust the viscosity and viscoelasticity of the melt, meet the requirements of foaming, and improve the physical and mechanical properties of the foam. The use of organic peroxide crosslinking agents can meet the above requirements, and generally, diisopropylbenzene peroxide is more ideal.
