EVA Plastic

EVA is a copolymer of ethylene and vinyl acetate. Its Chinese chemical name is ethylene-vinyl acetate copolymer (ethylene-vinyl acetate copolymer), and its English chemical name is Ethylene Vinyl Acetate Copolymer. EVA has a wide range of applications, and its annual market consumption in my country is increasing, especially in the shoemaking industry. 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, solar cell adhesives, etc.

What are the characteristics of EVA polymer?

High flexibility and transparency
Ethylene vinyl acetate (EVA) stands out for its excellent flexibility and soft touch. This property makes it easy to shape and not easy to deform, making it an ideal material for cushioning and padding. It is worth mentioning that EVA can remain flexible even at low temperatures, which further enhances its versatility.

Lightweight
Ethylene vinyl acetate is well known for its lightweight properties and is widely used in the production of protective clothing and footwear. This feature not only improves the comfort of the user, but also maintains its durability and flexibility.

Non-toxic
EVA is a non-toxic material, ensuring its safe use in various environments such as childcare, the medical industry, and food-related applications. The non-toxic nature enhances its versatility and broadens its application range.

Highly waterproof
EVA’s high water resistance allows it to withstand wind and rain, making it suitable for applications such as diving suits or raincoats exposed to water. This property ensures that EVA materials remain reliable and durable in all weather conditions.

Low melting temperature
One of the advantages of ethylene vinyl acetate is its low melting point. This property makes it versatile in the manufacture of textile products, allowing for easy bonding and helping to produce a wide range of products.

Excellent durability and resistance
Ethylene vinyl acetate is extremely resistant to abrasion, making it durable in a wide range of applications. It is also resistant to a wide range of chemicals, making it a solid choice for industrial environments where there is frequent contact with a variety of substances.

Noise reduction and low thermal conductivity
EVA’s noise reduction properties and its low thermal conductivity make it extremely valuable in applications where sound absorption or heat insulation is required. This makes it a very versatile material for a wide range of applications, including the production of products that help create a quieter or heat-insulating environment.

Recyclable
Ethylene vinyl acetate is recyclable, helping to reduce its impact on the environment. This property is particularly important in today’s society, where we are increasingly focusing on sustainability, and therefore, EVA is an environmentally friendly choice.

Application Areas ‌

EVA plastic (ethylene-vinyl acetate copolymer) has a wide range of applications. It is a general-purpose polymer with a molecular formula of (C2H4)x.(C4H6O2)y. It is flammable and has no irritating odor when burned.

A. The main application areas of EVA plastic include:

‌Shoemaking industry‌: EVA is widely used in the shoemaking industry, mainly used for the soles and interior materials of mid-to-high-end tourist shoes, mountaineering shoes, slippers, and sandals.

‌B. New energy field‌: In the new energy field, EVA is used for photovoltaic materials and solar cell adhesives, etc., especially in the photovoltaic industry, EVA is used for solar cell encapsulation film, and the annual consumption increases by 15%.

‌C. Wires and cables‌: EVA with a low vinyl acetate content is mainly used to manufacture films, wires and cables, etc.

‌D. Daily necessities‌: EVA resin plays an important role in many daily necessities fields due to its flexibility, resistance to environmental stress cracking and excellent weather resistance. It is often used as a manufacturing material for insulating leather bags for power wires, and is also widely used in household appliance accessories and V-sealing materials.

EVA recycled materials

A. Recycled plastic particles: Recycled EVA can be turned into recycled plastic particles through professional recycling treatment. These particles can be reused in the production of plastic products, such as soles, toys, cable materials, etc. This not only saves raw material costs, but also is environmentally friendly.

B. Blending modification: EVA recycled materials can also be blended and modified with other materials to improve the performance of the material. For example, mixing EVA recycled materials with certain additives such as plasticizers and stabilizers can improve the processing and use performance of plastics.

Environmental protection and economic benefits of EVA recycled materials

Recycling EVA can not only reduce the pollution of plastic waste to the environment, but also realize the effective use of resources. Through recycling and reuse, we can reduce the demand for new raw materials, thereby reducing the exploitation and consumption of natural resources. At the same time, the production cost of EVA recycled materials is relatively low, which can bring economic benefits to enterprises.
