  Good morning, everyone, today Fubo EVA foam manufacturer Xiaobian I work overtime, things are not much. I will update the relevant information about foam EVA lining.

Because there are too many kinds of foam, from the price of a few cents to several hundred, there are a variety of different processes, do not work density materials. How to choose EVA foam lining, the following simple points we can make a preliminary judgment:

First, will the taste be very pungent? First of all, you can smell the taste, A material EVA lining foam material has no odor at all, C-grade material is very pungent. EVA lining made of EVA foam material often sold on the market is basically A material, AB material, B material, these materials also have tasteless and low taste, and the price is different. So step one, smell.

Second, the appearance of the foam EVA sheet can see the fineness and flatness of the foam, to see if there is an obvious sand pit. It also depends on whether the seam of the data is smooth, whether the seam is obviously prominent, whether the thickness of the data is uniform, whether there is obvious color difference and so on. C material generally has A lot of fine holes, B material also has fine holes, but not much, A material basically has no fine holes.

Three: processing molding process, if it is deeply processed parts, check whether the appearance of the entire product has burrs, whether the edges are smooth, and whether the joints can be bonded. Whether there is degumming phenomenon after laminating.

Four: Pinch, that is, pinch EVA foam lining, see the feel. Pinch the elasticity is not good, or a pinch is bad, certainly not suitable. The foam material feels more comfortable and a little elastic, which means that it is OK.
