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...
