EVA material introduction and application

图片
  EVA material introduction and application EVA material  is an ordinary material for machines. It is a relatively common low-to-medium material in daily life. The finished product made of it has good flexibility, shock resistance, non-slip, and strong resistance to pressure. For example, our common EVA slippers, cotton Shoes, EVA mobile phone protective cover, EVA IPAD protective cover, etc. The polymerization method uses high-pressure bulk polymerization (plastics), solution polymerization (PVC processing aids), emulsion polymerization (adhesives), and suspension polymerization. Once the ethylene (VA) content is higher than 30%, emulsion polymerization is used, and the vinyl acetate content is low. Use high-pressure bulk polymerization. EVA sole refers to a sole made of EVA material. EVA soles have high resilience and tension resistance, high toughness, good shock resistance, cushioning properties, excellent heat insulation, heat preservation and cold protection and low temp...

Why are toolbox linings mostly EVA insert?

  Why are toolbox inserts mostly EVA insert? Most of the inserts in the toolboxes we see daily are mainly  EVA inserts , because it is mainly used for filling and has strong impact resistance and strong protection. The thickness of the protective pad is 17cm, and the thickness (finished product) after hot pressing is 14-16mm. The inner lining of the toolbox is also called  Eva Foam Tool Inserts , which is used to protect the tools in the toolbox. Its material is mainly EVA. Its purpose is to prevent the tool from scratching and rusting, and can play the role of corrosion resistance, aging resistance, impact resistance, moisture resistance, beauty, and lightness. The EVA lining material of the toolbox can be divided into: low density EVA, high density EVA, environmentally friendly and non-toxic. The normal density range of black, white and color is 25P to 50P. In the production process of EVA manufacturers, the thickness of EVA lining ranges from 10mm to 80mm. The positive...

What is the requirement for EVA insert to be formed once?

  EVA insert packing  is a kind of insert material used in product packaging, usually made of EVA material. The scope of application of EVA insert is very wide, which can prevent the packaged product from being damaged during transportation. EVA lining is a product that is very easy to process, and it has good fire-proof and shock-proof effects. EVA is easy to process and shape, and is usually formed at one time. There are many requirements for one-time molding of EVA lining. LJL EVA products manufacturers will introduce a few more common requirements. 1. In the production and processing process, the size of the product should be the same as the size of the product, and the EV lining should be produced and processed according to the size and shape of the product. 2. When processing EVA materials, the one-time forming material should be a single piece and cannot be spliced together. 3. In the process of processing and production, the thickness and depth must be ensured to prote...

The characteristics of EVA products are very good

  After the  EVA product  is foamed, the EVA product has good heat insulation performance. Because EVA products have good thermal insulation properties, it also means that they will have very good thermal insulation properties. In short, it can resist both severe cold and high temperature. EVA products have good processing properties. When it is processed, it can be laminated or cut. Because it is very easy to process, there are a variety of EVA products on the market. In addition, the product is very good in water resistance. Putting this material in the water will not have any effect on the product, just take the product out and use it. EVA products are relatively less harmful to the environment. With the rise of social patterns, people's awareness of environmental protection and the rise of EVA products in the packaging industry play a very critical role. EVA products and materials will be everywhere in people's lives in the future. 1. The elasticity of EVA products is...

What is EVA molding material?

  EVA molding material  is composed of ethylene-vinyl acetate copolymer, and it is made by copolymerization of ethylene and vinyl acetate, and its polymerization method is high-pressure bulk polymerization, which has very good performance and can be used in many industries. , Play a role in usage. Characteristics and uses of EVA: EVA particles can be produced into various types of EVA sheets, and then the sheets are processed in various ways. For example, punching can be used as packaging lining, and hot pressing can be made into shoe soles. Biodegradable: Will not harm the environment when discarded or burned. EVA materials can be used in electronics, hardware, and toy industries. Similar in price to PVX: EVA is more expensive than toxic PVC, but cheaper than phthalate-free PVC. Does not contain phthalates: suitable for children's toys and will not produce plasticizer release hazards. High transparency, softness and toughness. The scope of application is very wide, super low ...

Uses of EVA materials

  EVA material is a new type of environmentally friendly material, a product of foam, and it is also called eva sponge. EVA foam can also follow up customer requirements to produce the required colors, which are divided into A material, B material, C material, low-odor environmentally friendly materials and non-environmentally friendly materials. EVA foaming process: at the decomposition temperature of the foaming agent, a large amount of gas is released to form a foam core. After the pressure is released suddenly, the release of the foam core causes the expansion of EVA and other materials to form a foamed material. EVA foam foam material grade: C-level, B-level, A-level, 3A-level, CR material, high-elastic EVA material, rubber EVA material, etc. It is often used as the lining of tool boxes and packaging boxes, and is also commonly used in environmentally friendly toy craft products. The advantages of EVA foam: EVA rubber and plastic products are new environmentally friendly plast...
