What material does EVA belong to?
In recent years, environmentally friendly materials and high-performance synthetic materials have attracted much attention, among which EVA (ethylene-vinyl acetate copolymer) is widely used in many fields due to its unique properties. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce in detail the material characteristics, application scenarios and market trends of EVA.
1. Basic characteristics of EVA material
EVA is a thermoplastic resin copolymerized by ethylene (Ethylene) and vinyl acetate (Vinyl Acetate). Its properties depend on the content of vinyl acetate (VA). The following are the main characteristics of EVA:
| Features | Description |
|---|---|
| Flexibility | The higher the VA content, the softer and more elastic the material is. |
| chemical resistance | Good resistance to acids, alkalis and solvents. |
| Transparency | The transparency of EVA with high VA content is close to that of PVC. |
| Environmental protection | Recyclable and some models biodegradable. |
2. Application fields of EVA
EVA is widely used in the following fields due to its excellent performance:
| field | Specific applications |
|---|---|
| shoe material | Midsoles for sneakers, slippers, and more, provide cushioning and comfort. |
| packaging | Lining for food packaging and electronic products, shockproof and moisture-proof. |
| photovoltaic | Solar cell encapsulation film with good weather resistance and light transmittance. |
| toys | Spliced floor mats and children's toys, safe and non-toxic. |
3. The relationship between recent hot topics and EVA
In the past 10 days, EVA materials have appeared frequently in the following hot topics:
| hot topics | Association with EVA |
|---|---|
