Frequently Asked Questions

What are the applications of Ethylene Vinyl Acetate EVA?

EVA is a copolymer of ethylene and acetic acid. The Chinese chemical name: Ethylene Vinyl Acetate Copolymer, and the English chemical name: Ethylene Vinyl Acetate Copolymer. EVA has a wide range of applications, especially in the shoe industry, where it is used in the soles and interior materials of mid-to-high-end tourist shoes, hiking shoes, slippers, and sandals. It is also widely used in the field of new energy, such as photovoltaic materials and solar cell adhesives.1. The main products of EVA with vinyl acetate content below 5% are films, wires and cables, LDPE modifiers, adhesives, etc.; 2.EVA products with vinyl acetate content between 5% and 10% are elastic films, etc.; 3. EVA with 20-28% vinyl acetate is mainly used for hot melt adhesives and coating products; EVA is made by copolymerization of LLDPE (linear low density polyethylene) and acetic acid (VA).

Comment on the water repellency of Ethylene Vinyl Acetate

According to the water resistance of EVA emulsion polymer, it can be divided into two categories: general purpose and waterproof. EVA polymer of general product grade has good rigidity, high bonding strength, but poor water resistance; Waterproof product brand EVA polymer has good flexibility, good water resistance, but low bonding strength. According to the application performance of EVA, copolymer composition and the third monomer type of copolymerization, EVA emulsions can be divided into two categories: adhesive and spinning. Adhesive type EVA is mostly used as a general purpose adhesive, and textile type adhesive is mostly used as a textile fiber adhesive, but there is no absolute boundary between the two.

What are the precautions for operation ?

Pleasec provide closed operation and good natural ventilation conditions. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that the operator wear a self-priming filter dust mask, chemical safety glasses, protective work clothes, and rubber gloves. Keep away from fire and heat. No smoking in the workplace. Use explosion-proof ventilation systems and equipment. Avoid producing dust. Avoid contact with oxidants and alkalis. When handling, light loading and unloading should be done to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. Empty containers may have harmful residues.
