What kind of material is EVA product and what kind of material is EVA?

EVA material is the common name we define, the full English name is ethylene-vinyl acetate copolymer, its chemical name is ethylene-vinyl acetate copolymer, is an extremely common material, is a more common type of midsole material in daily life, the finished product made of it has good flexibility, shockproof, anti-slip, strong pressure resistance, such as our common EVA slippers, cotton shoes, EVA mobile phone case, EVA iPad protective case, etc.

Use 1: EVA material can be used to make household appliances and daily necessities such as conduits, gas pipes, civil construction boards, containers, etc. for household refrigerators.

Use 2: EVA material can be used to make packaging films, gaskets, medical equipment, hot melt adhesives, cable insulation, etc.

Application 3: EVA materials are widely used in wireless book binding, digital product shell structural parts, furniture edge banding, automobile and household appliance assembly, shoemaking, carpet coating and metal anti-corrosion coating.

Area 1: Because EVA material has strong flexibility, chemical resistance and good elasticity, it is widely used in the sole and interior materials of various footwear.

Field 2: EVA material has the inclusiveness and cross-linkability that other materials do not have, and it is because of its performance that it is suitable for use in halogen-free flame retardant cables, semiconductor shielded cables and two-step silane cross-linked cables, and is also widely used in industrial and manufacturing products because of this performance.

This question should be asked in the chemical category, hehe. EVA is actually a plastic composed of ethylene (E) and vinyl acetate (VA). The ratio of these two chemistries can be adjusted to suit different applications, and the higher the vinyl acetate (VA) content, the higher the transparency, softness and toughness.

EVA material is an extremely common material, is a more common kind of midsole material in daily life, the finished product made of it has good softness, shockproof, anti-slip, strong pressure resistance, such as our common EVA slippers, cotton shoes, EVA mobile phone case, EVA iPad case, etc.

Polymerization method: high-pressure bulk polymerization (for plastics), solution polymerization (PVC processing aid), emulsion polymerization (adhesive), and suspension polymerization. Emulsion polymerization is used for vinyl acetate (VA) content higher than 30%, and high-pressure bulk polymerization is used for vinyl acetate content low.

EVA soles refer to soles made using EVA material. EVA sole has high resilience and tension resistance, high toughness, good shockproof, cushioning performance, heat insulation, heat insulation, cold protection and low temperature performance, can withstand severe cold and exposure, closed bubble holes, good sound insulation effect, closed bubble cell structure, non-absorbent, moisture-proof, good water resistance, resistant to seawater, grease, acid, alkali and other chemicals, antibacterial, non-toxic, tasteless, non-polluting.

Answer 1: Foam shoe materials are the most important application fields of EVA resin in China. Because EVA resin blended foam products have softness, good elasticity, chemical resistance and other properties, they are widely used in the soles and interior materials of medium and high-end tourist shoes, hiking shoes, slippers and sandals. It is often used for cosplay prop making and model making.

2. The main purpose is to produce functional shed film, adding a certain amount of EVA resin to make the shed film, which not only has a high light transmittance, but also has a great improvement in anti-fog drop performance, which can generally exceed 4 months.

Take a plastic.

It is formed by the copolymerization of ethylene and acetic acid, and due to the introduction of vinyl acetate monomer in the molecular chain, the high crystallinity is reduced, and the toughness, impact resistance, packing solubility and heat sealing performance are improved.

It is widely used in foam shoe materials, functional shed films, packaging molds, hot melt adhesives, wires and cables and toys, especially in the footwear industry, and is used in the soles and interior materials of medium and high-end tourist shoes, hiking shoes, slippers and sandals.

Classification: 1. EVA with vinyl acetate content below 5%, its main products are films, wires and cables, LDPE modifiers, adhesives, etc.;

2. EVA products with vinyl acetate content of 5% and 10% are elastic films, etc.;

3. EVA with vinyl acetate content of 20-28% is mainly used for hot-melt adhesives and coating products.

For us laymen, we should be confused when it comes to EVA, and we don't know what it is and what it is used for. In fact, it is very common around us, as long as you pay attention to it, you will see its figure, but when we see its finished product, we don't know what material EVA is, it is inevitable that we will feel that our knowledge is shallow, today I will take you to seriously understand what EVA is and its use and function, I hope you can gain something.

1. What kind of material is EVA?

EVA is a material that is rubber-elastic at room temperature and can melt and flow at high temperatures. EVA material is made of ethylene and acetic acid copolymerization, EVA application field is still quite extensive, and China's annual market consumption is also increasing, especially in the shoe industry, is used in high-end tourist shoes, hiking shoes, slippers, sandals soles and interior materials.

EVA is characterized by good softness, rubber-like elasticity, good flexibility at -50, transparency and surface gloss, good chemical stability, good anti-aging and ozone resistance, and non-toxicity. It has good mixability, colorability and molding processability with fillers. EVA is widely used in foam shoe materials, functional shed films, packaging molds, hot melt adhesives, wires and cables, toys and other fields.

Second, the main role of EVA.

1. EVA materials generally have very good flexibility and strong chemical corrosion resistance, in addition, EVA materials also have strong elasticity, so EVA materials can make a variety of footwear products, which can make us feel more comfortable in the process of using EVA products, and the service life will be increased.

2. EVA material has a good inclusiveness and cross-linkable type, which is not available in other materials, so it can be used in the industrial field and can also be used in some production supplies.
