eva foam suppliers

  EVA Foam insert  is a kind of lining material used in product packaging, usually made of eva material. The scope of application of eva lining is very wide, which can effectively prevent the packaged product from being damaged during transportation. The 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, usually one-time molding, and there are many requirements for one-time molding of eva lining. 1. In the process of production and processing, the size of the product should be the same as the size of the product, and the eva lining should be produced and processed according to the size and shape of the product. 2. In the process of processing and production, the material formed at one time 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 protect the product, and the workmanship should be accu...

The  packing box eva inner lining , in terms of material, there are packing box eva inner lining, sponge inner lining, EPE pearl cotton inner lining, paper inner lining, etc. Their performance is distinguished: 1. EVA lining, in terms of performance, there are environmentally friendly and non-environmentally friendly eva, as well as anti-static eva and fireproof eva. There are many names for eva lining, such as eva tray, eva lining, eva box and so on. In terms of hardness, there are many 38 degrees, 50 degrees, 60 degrees, 70 degrees, etc. In terms of color, there are always available, but the color is different. Some colors need to be customized, such as white, black, color, etc., white and Black is a very common color. In terms of performance, there are environmentally friendly and non-environmentally friendly eva, as well as anti-static eva and fireproof eva. 2. Sponge lining, in terms of performance, it can be divided into environmental protection sponge lining, anti-stati...

  The hardness of   EVA   is divided into: foam tube and EVA material EVA foam tube is also called NBR foam tube, its hardness is divided into A+ dense A dense B+B dense and C dense. Generally, B density is used more, EVA materials have 38-70 degrees, which is relatively common before, and there are less than 38 degrees. Generally use C-type hardness tester to measure, choose a relatively flat area, the thickness is above 6MM, and the measurement force is 1KG. A weight of 1KG can be used on the top of the hardness tester. Expand Content and performance: The performance of EVA has a great relationship with the content of vinyl acetate (va). When the content of VA increases, its resilience, flexibility, adhesion, transparency, solubility, and stress crack resistance And impact will increase. When the content of VA decreases, the rigidity, wear resistance and electrical insulation of EVA will increase. Generally speaking, when the VA content is in the range of 10%-20%, it is...
