Introduction
In today’s era where mobile devices are everywhere, mobile power has become a must-have for people to travel. A good mobile power supply not only needs a strong power reserve, but also needs a sturdy, practical and portable shell to protect it. The portable multifunctional EVA mobile power zipper bag came into being. It has been favored by many consumers for its unique design and excellent performance. Today, let’s take a deep look at the EVA material used in this product and its significant differences from ordinary materials.
I. Understanding EVA materials
(I) Definition of EVA materials
EVA, the full name of which is ethylene-vinyl acetate copolymer, is a high molecular polymer copolymerized by ethylene and vinyl acetate. Its general vinyl acetate (VA) content is between 5%-40%. Compared with polyethylene (PE), EVA has introduced vinyl acetate monomers into the molecular chain, thereby reducing the high crystallinity and improving toughness, impact resistance, filler compatibility and heat sealing properties.
(II) Characteristics of EVA materials
Good flexibility and elasticity: EVA material has excellent flexibility and can maintain its softness even in low temperature environments without becoming brittle. This flexibility enables it to withstand a certain degree of bending and extrusion, providing good buffering protection for the mobile power supply. At the same time, its elasticity is also very good, and it can quickly return to its original state and will not be deformed by external forces, ensuring the integrity of the appearance and internal structure of the mobile power supply.
Excellent impact resistance: EVA material has extremely strong impact resistance and can effectively resist external impact and impact. In daily use, the mobile power supply may accidentally fall or be hit, and the high impact resistance of EVA material can minimize the damage caused by these accidents to the mobile power supply, protect the internal electronic components from damage, and extend the service life of the mobile power supply.
Strong corrosion resistance: EVA has good corrosion resistance to various chemicals such as acids, alkalis, salts, etc., which allows it to maintain good performance under various environmental conditions. Whether it is a humid environment or exposed to some corrosive substances, EVA material will not be easily corroded, thereby ensuring the safety and reliability of the mobile power supply.
Good waterproof and moisture-proof performance: EVA material has a closed cell structure and does not absorb water, so it has good waterproof and moisture-proof performance. This is very important for mobile power supplies because it can prevent moisture from entering the mobile power supply and causing short circuits or other electrical faults. Even if it is used on rainy days or in humid environments, it can be used with confidence without worrying about moisture damaging the mobile power supply.
Easy to process and shape: EVA material has no fixed joints, and hot pressing, cutting, and laminating are relatively easy to process. This means that it can be easily processed into various shapes and sizes to meet the mobile power zipper bags of different design requirements. Whether it is a complex appearance or a delicate internal structure, EVA material can be achieved through appropriate processing technology, providing a lot of space for the diversified design of products.
Environmentally friendly and non-toxic: EVA material is a new type of environmentally friendly plastic foam material, which is antibacterial, non-toxic and tasteless, and has no pollution. It complies with relevant standard toy regulations, does not contain phthalates, is suitable for children’s toys, and does not produce the risk of plasticizer release. Therefore, mobile power zipper bags made of EVA material are safe and harmless to the human body and the environment, and consumers can use them with confidence.
2. Differences between EVA materials and ordinary materials
(I) Differences from polyethylene (PE) materials
Crystallinity and transparency: PE material is a crystalline polymer with high crystallinity, so its transparency is relatively low. However, due to the introduction of vinyl acetate monomer, the crystallinity of EVA material is reduced and the transparency is significantly improved. This means that the mobile power zipper bag made of EVA material can have higher transparency, allowing users to see the mobile power inside more clearly, increasing the beauty and visibility of the product.
Flexibility and impact resistance: Although PE material also has certain flexibility and impact resistance, compared with EVA material, EVA performs better in these two aspects. The flexibility of EVA material enables it to bend and deform better when subjected to external force without breaking or damage; its high impact resistance can more effectively resist external impact and provide more reliable protection for the mobile power.
Low temperature resistance: In low temperature environment, PE material will become more brittle and hard, and its performance will be affected to a certain extent. EVA material has super low temperature resistance, and can maintain good flexibility and elasticity even in an extreme low temperature environment of -70℃. This is a very important advantage for mobile power supplies that need to be used in cold areas or low temperature environments, ensuring the normal use of mobile power supplies under various temperature conditions.
(II) Differences from polyvinyl chloride (PVC) materials
Environmental performance: PVC materials may add some chemicals such as plasticizers and stabilizers during the production process. These substances may release harmful substances in some cases, causing certain harm to the environment and human health. EVA material is an environmentally friendly material that does not contain harmful substances such as heavy metals and phthalates. It is biodegradable and will not cause harm to the environment when discarded or burned.
Touch and flexibility: EVA material has a softer touch and stronger tensile toughness than PVC. It feels sticky but has no glue on the surface, giving people a comfortable feeling. In contrast, PVC material has a relatively hard touch and is not as flexible as EVA material. Therefore, when making mobile power zipper bags, EVA material can provide a better user experience and comfortable grip.
Corrosion resistance: EVA materials have stronger corrosion resistance to various chemicals and can better resist the erosion of acids, alkalis, salts and other substances. When PVC materials are exposed to certain chemicals for a long time, they may age, discolor or degrade in performance. Therefore, EVA materials have more advantages in corrosion resistance.
(III) Differences from ordinary foam materials
Density and weight: Ordinary foam materials such as sponges have relatively low density and light weight. The density of EVA materials is between 0.91 and 0.93, which is relatively heavier. This makes the mobile power zipper bag made of EVA material have a certain sense of weight in the market, giving people a more solid and durable feeling.
Resilience: EVA materials have good resilience and can quickly return to their original shape after being squeezed, without collapse or deformation. Ordinary foam materials may gradually lose elasticity after long-term use or repeated squeezing, resulting in shape changes, affecting their protective performance and appearance.
Waterproof performance: Ordinary foam materials such as sponges have a certain degree of water absorption and are easy to absorb moisture, which leads to problems such as dampness and mold. EVA materials have a closed cell structure, do not absorb water, and have excellent waterproof performance. They can effectively prevent moisture from entering the mobile power supply and ensure the safe use of the mobile power supply.
(IV) Differences from leather materials
Breathability: Leather materials have good breathability, but EVA materials have relatively weak breathability. However, EVA materials can be punched or compounded with other breathable materials through special processes to improve their breathability and meet certain usage requirements.
Durability and wear resistance: EVA materials have good durability and wear resistance and can withstand long-term use and friction. In contrast, leather materials may experience wear and cracking during long-term use and require more care and maintenance.
Price and cost: The price of EVA materials is relatively low and the cost is low, which makes the mobile power zipper bag made of EVA materials have a certain price advantage in the market and can meet the needs of more consumers. The price of leather materials is usually high, which leads to a corresponding increase in the cost of mobile power zipper bags made of leather, and the price is relatively high.
