Can EVA foam be replaced with EPE pearl cotton sponge?


EPE pearl cotton is an earthquake-resistant packaging material such as computer hardware. Foam sponge was used in the past, but now more pearl cotton is used. Its seismic effect is better it is easy to fix.



EVA foam is a kind of foam. Foam is a material that has been foamed by plastic particles to form foam. The foam is divided into PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, PORON, CR, EVA, bridging PE, SBR, EPDM, etc. EVA is one of the foam products, it is also called EVA sponge. EVA can be foamed according to individual requirements, the hardness can also be adjusted according to requirements. Foam has a series of characteristics such as elasticity, light weight, fast pressure-sensitive fixation, convenient use, free bending, ultra-thin volume, reliable performance.


The main characteristics of eva foam products are high precision, the uniformity of the entire roll of materials is highly accurate, it can be cut with confidence after coating, without delamination, has a high degree of compatibility with adhesives, will produce non-sticky The main specifications are 41" (1040mm) 42" (1070mm), which are suitable for hot melt adhesive acrylic oil coating.

Commonly used sponges are made of wood cellulose fibers foamed plastic polymers. In addition, there are also natural sponges made of sponge animals. Most natural sponges are used for body cleaning painting. In addition, there are three types of synthetic sponges made of other materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (high-absorbent material without obvious pores) polyester.


1. A relatively common midsole material, usually called a foam, has a certain cushioning effect, but this material is very slippery, so it is generally mixed with hard rubber. EVA is a common material is mostly used Electronic appliances, plastics other products.


2. Daily necessities: foam shoe materials, functional shed films, packaging films, hot melt adhesives, wires, cables toys.


EVA self-adhesive method:


1. Easy to use: No need to punch holes, just gently take out the single EVA formed on each large piece of EVA, the release paper at the bottom will automatically separate the foot pad, then press to the desired product position.


2. Strong adhesion: The pressure-sensitive adhesive technology (3Mpad) with long-lasting performance can fix the EVA in place help prevent sliding falling off. Domestic double-sided adhesives are mostly used: hot melt adhesive, oil glue, embroidery glue water glue; imported double-sided adhesives: 3M, NITTO (Nitto), TESA (Tessa), SONY (Sony), Hi-Bon (Hitachi).
