What is EVA material for shoe soles

EVA is an ethylene vinyl acetate copolymer that has good flexibility, elasticity, and corrosion resistance. Due to its high foaming rate, low density, and good cushioning performance, it is widely used as a sole material. In the sole manufacturing industry, EVA is a common lightweight and environmentally friendly material. It can be made into foam through foaming agent to obtain a light and soft sole. Due to its good elasticity and durability, the EVA sole can effectively alleviate foot pressure and impact, providing better comfort and support. In addition, EVA soles also have good processing and adhesive properties. It can be well combined with other materials such as rubber and plastic to create various styles and functions of shoe soles. Therefore, EVA has been widely used in the sole manufacturing industry. In addition to the sole manufacturing industry, EVA is also widely used in other fields. For example, it can be used to manufacture packaging materials, waterproof materials, sound insulation materials, etc. Due to its excellent processing performance and corrosion resistance, EVA can also be used to manufacture pipelines, containers, etc. In short, EVA is a widely used lightweight and environmentally friendly material. In the sole manufacturing industry, it is highly favored for its excellent performance and wide range of applications. Meanwhile, as people's attention to environmental protection and health continues to increase, EVA, as an environmentally friendly and non-toxic material, will also be more widely used.

What materials are usually used for sports shoes

1. Rubber: Used for various sports shoe soles, it has good wear resistance, good elongation, stable shrinkage, good hardness, and good flexibility, but it is heavy and prone to frost; 2. Polymer polyurethane synthetic material: commonly used as a midsole for basketball and tennis shoes, and can also be directly used as a sole for casual shoes. It has good elasticity, oxidation resistance, corrosion resistance, environmental friendliness, and is not easily wrinkled. However, it has strong water absorption, is not resistant to water, and the sole is prone to decay; 3. Ethylene acetate copolymer, polymer material: commonly used as midsole for jogging, jogging, casual shoes, and foot training shoes. Lightweight, elastic, flexible, not easily wrinkled, with excellent coloring properties, suitable for various climates, but easy to absorb water, not easy to corrode, unfavorable for environmental protection, and easy to get dirty; 4. Secondary high-pressure molding product: It is the main material used for the midsole of running shoes, tennis shoes, and basketball shoes, and can also be used for the outsole of casual shoes. Lightweight, elastic, with a fine appearance and good softness, but not easily corroded, which is not conducive to environmental protection. It is prone to wrinkles and shrinkage at high temperatures; 5. TPR: Made by hot melt injection molding of TPR pellets, it is easy to shape and inexpensive, but the material is heavy, has poor wear, poor flexibility, poor bending ability, and shock absorption ability.

What are the advantages of TPE foam board

TPE (Thermoplastic Elastomer) foam board has the following advantages: 1. Good softness: TPE foam board has good elasticity and softness, which can adapt to various complex surface shapes, providing better cushioning and protection effects. 2. Lightweight: TPE foam board is lighter than traditional foam materials, which can effectively reduce the overall weight of the product and reduce the burden of handling and transportation. 3. Wear resistance: TPE foam board has high wear resistance, which can effectively resist friction and wear, and extend the service life of the product. 4. Weather resistance: TPE foam board has good weather resistance and can be used in various harsh indoor and outdoor environments, not easily affected by natural factors. 5. Environmental friendliness: TPE foam board does not contain harmful substances and meets environmental requirements. During the production process, harmful gases and wastewater are not emitted, and there is no pollution to the environment. In summary, TPE foam board has advantages such as softness, lightness, wear resistance, weather resistance, and environmental friendliness, and is suitable for packaging, protection, and sound insulation applications in various fields.

Do you know how many types of soles shoes can have?

Simply put, the soles of shoes can be divided into: Cloth sole, leather sole, natural rubber sole, and chemically synthesized rubber sole. 1、 Cloth bottom The origin of cloth soles is relatively long. With the development of ancient agricultural technology, cotton fiber spinning and weaving began to be widely used, and thousand layer cloth soles made of layer by layer cotton cloth began to be popular. 2、 Skin base Shoes with genuine leather soles are generally high-end leather shoes with breathable and sweat wicking characteristics, so they are not prone to athlete's foot. However, due to the need for a large amount of high-quality natural leather, which is costly and not waterproof, it can be used in fewer scenarios. Leather soles are mostly used in the production of formal shoes, and currently top luxury brands such as Silvano Lattanzi, Berluti, and John Lobb still retain the craftsmanship of making leather soles. 3、 Natural rubber sole The ingredients of natural rubber sole come from the raw rubber on the rubber tree, and latex is the quenched essence of the raw rubber. The advantage of natural rubber is that it is very soft and elastic, and can be used in various scenes, such as indoor sports shoes. Natural rubber has strong balance, wear resistance, and grip. Due to the scarcity of natural collection, casual shoes with natural rubber soles are extremely rare. TOD'S Doudou sole, which is used for anti slip, is made of rubber, and MEPHISTO's rubber sole, which is said to be 100% natural rubber and will rebound when touched. 4、 Chemically synthesized rubber Chemically synthesized rubber is produced by artificial synthesis methods, characterized by its low cost. Different types of rubber can be synthesized using different raw materials to create functions that are suitable for different usage scenarios. Wear resistant rubber used in tennis shoe soles, environmentally friendly rubber made from recycled natural rubber, air rubber with certain shock absorption function in rubber, and hard rubber used in multifunctional shoes and basketball shoes.
